Da Nang Case Study
In 2007, Congress collected $130 million dollars to assist health issues related to Agent Orange, thus including direct care as well as research [21].
Since Agent Orange's effects range greatly from person to person based on age, exposure rate, and concentration, it is not as simple to classify as a
virus or bacteria. Therefore, a cure–all for Agent Orange is not possible, treatment for the symptoms is the only way to cure those affected. Although
"cleaning" where there is a greater concentration of dioxin in the environment can stop future cases of dioxin poisoning. So to protect people before
Agent Orange can affect them, it must be "cleaned" by different organizations to promote the health of Vietnamese citizens.
Due to all the believed health effects, the veterans of the war from the United States, New Zealand, and Australia made a case against the companies

Agent Orange : Medical Ethics
Motivation: Throughout the past Forty years the Vietnam war and it's after effects have shaped and changed so many individuals and their lives. I
will expose a deeper look at what actually occurred during the war and most importantly what actually caused the millions and millions of lives; both
Vietnamese, Japanese, and American. Problem statement: With war comes after effects and throughout the past Forty years many American Veterans
from Vietnam have had health complications and issues due to the widespread use of Agent Orange during the duration of the war, especially at base
camps. These ailments, cancers, and diseases can be traced back to a series of Chemical Defoliates or herbicides that have left traces of Dioxin with
whoever or wherever it once was used or sprayed. Conclusions: For all of these Veterans affected by this chemical unknowingly deserve restitution and
better yet compensation for their medical issues and bills. Agent Orange: Medical Ethics Agent Orange was widely used throughout the entire Vietnam
war by Anti–Communist forces. In 1962, 85% of the food sources in Vietnam were targeted to be sprayed with Agent Orange from the air.
Helicopters and planes were used in order to do aerial drops consistently and easily. On top of the use of Agent Orange on the forests of Vietnam,
United States military bases used this herbicide daily if not weekly in order to keep the lands on the bases clean and low amounts to no vegetation on

Polychlorinated Biphenyls: Nature and Management
PCB: Nature and Management Introduction The history of PCB's (known as the Polychlorinated Biphenyls) dates back to the early 1930's. There is
no record of the chemical existing in nature prior to this. This chemical substance is a type of oil that is chlorinated. It is hardly reactive with other
substances. It is not even prone to rapid combustion and serves as an electrical insulator. The chemical also maintains its structural integrity when
subjected to high temperature and pressure. This led the scientific community to consider PCB's as the perfect replacement for dielectric liquids and
as a form of insulation within capacitors and major transformers (Forsberg, 2007). The property of PCB enabled it to be an immediate candidate for
use in hydraulics, light (fluorescent) ballasts and heat transfer mediums. Its usage was further expanded to include tasks such as making pigments,
plasticizers and industrial grade wax. Discussion Identification It is important for a Food safety professional to be able to detect the effects of PCB's
on humans, animals and the environment. This provides them with important cures in how to contain and eventually eradicate the exposure to the
PCB's. In human beings the first sign of PCB exposure and poison is chloracne and rashes on the skin. The PCB is fat soluble so it will dissolve in
the dermis and any other layer than contains fat. The detection of PCB in a human source is important because it shows that there is a pre–dominant

Retinol Hypothesis
The relationship between polychlorinated biphenyls and thyroid hormones and retinol was studied focusing on two groups of female polar bears
(females with cubs of the year and females without cubs) and within a group of males. PCB is an industrial organochlorine chemical by–product which
has toxic effects. Since PCB is volatile it is deposited in the polar regions. PCB negatively impacts brain development due to their impact on the thyroid
system. It also causes menstrual dysfunction, anovulation, and miscarriage. The polar bear feeds on the seals which contain OCs in their fatty tissues so
the PCB congeners can greatly accumulate in their body. There are two main types ofThyroid hormone : T4 and T3. Retinol is vitamin A which is also
affected by PCB. Retinol is a fat–soluble vitamin needed for ... Show more content on Helpwriting.net ...
PCB also affects the thyroid enzymes. In this study, the global null hypothesis was there is no relationship between PCB and Thyroid hormones and
Retinol in female and male bears. The alternative hypothesis was that there is a relationship present between PCB and Thyroid hormones and Retinol
in female and male bears. The treatment group in the study was that the expecting polar bear mothers fasted for at least three months and the control
group in the study was the mothers who were not pregnant and the males. Because intercourse, reproduction, and sustenance of the polar bears affect
the level of thyroid hormone and retinol, there are likelihoods of the effects of PCBs and other OCs on thyroid hormones and retinol status may vary.
The bears were all from the Svalbard population. In order to prevent confounding results occurring from seasonal variation, the study took place in

Economies Of Scale And Scope
Economies of Scope:
Economies of scale and scope help producers lower their cost by producing the next unit of output at lower costs this trend continues until production
reaches a level of diseconomies of scale where production is no longer running as efficient as it should. This tends to increase the barriers to entry for
new competitors as when they enter the market they will experience a higher cost of production. Why? Solely because they have smaller economies
of scale and cannot afford to sell the product at the same price as other much larger firms. Generally, economies of scale and scope positively affect
General Electric. Since General Electric is one of the biggest conglomerates in the world it has the opportunity to offer products and services through
the same organization. These products might be highly unalike but due to the wide range of businesses covered by GE the prospect is there. For
example, GE, in order to continue a healthy relationship with valued customers, has allowed the multimillion dollar purchase of its jet engines to be
financed over long periods of time. The catch is that these finance opportunities are usually done via a leasing arrangement from GE Finance. In recent

Dioxins are environmental pollutants. They belong to the "dirty dozen" – a group of dangerous chemicals known as persistent organic pollutants
(POPs). Dioxins are of concern because of their highly toxic potential. Experiments have shown they affect a number of organs and systems. Once
dioxins enter the body, they last a long time because of their chemical stability and their ability to be absorbed by fat tissue, where they are then stored
in the body. Their half–life in the body is estimated to be 7 to 11 years. In the environment, dioxins tend to accumulate in the food chain. The higher
an animal is in the food chain, the higher the concentration of dioxins. Dioxin is mainly a result from natural processes, like volcanic eruptions or

The EPA considers a 200 miles stretch of the historic Hudson to be one the largest Superfund sites in our nation. What was GE's environmental stance
during the latter part of the 20th century? In three words Dismal, Denial, and Diswoned! Mr. Jack Welch's, reigned as Chairman and CEO of GE
during the years of 1981–2001, taking over from his predecessor Reginald H. Jones. Regarding the case of GE's dumping of PCB's into the Hudson,
a rather frosty Welch negotiated with the state of New York, settling to pay a mere $3 million dollars for the damage caused to the Hudson River.
According to Cray (2001), "GE executives probably hoped the deal would bury the issue forever, and that everyone concerned about the PCBs
(polychlorinated biphenyls) lying on the bottom of the river would let nature take its course." (Multinational Monitor, 2001) During that time Jack
Welch's stance on the accusations resulted in historical comments filled with denial, Jack said, during a 60 Minutes interview, "The word 'dump' is
used! We didn't dump! We had a permit from the U.S. government and the State of New York to do exactly what we did. Do you think I'd come to
work in a company that would do that or condone that? I wouldn't do it, Lesley! This is nuts!" (60 MINUTES, October 29, 2000) GE would go on to

Environmental Impact and Sustainability Issues related to PBDEs
In chapter fourteen of our textbook, Environment: The Science Behind The Stories, it is made clear that the United States does not use the
precautionary principle approach when it comes to evaluating how toxic a substance is (Withgott & Laposata, 2014, p. 382). This lack of precaution
has proven to be dangerous when it comes to chemicals, especially when using polybrominated diphenyl ethers (PBDEs). PBDEs are chemically
engineered flame retardants used during the manufacturing process of clothing, bedding, and many other household goods. These flame retardants work
by eliminating the fire's oxygen supply, resulting in less damage to the item and a decrease in the chance of a larger fire (Hester & Harrison, 2013, p.
45). While PBDEs may have been necessary during a time when there were fewer fire regulations, it is clear that the negative effects of these flame
retardants outweigh the benefits in today's times.
According to the journal of Environmental Science & Technology (2016), the toxicity of PBDEs was first discovered in Sweden, when a study
exposed an unsafe and increasing level of flame retardants in the breast milk of women. This study showed that PBDEs were potentially toxic and
highly bioaccumulative, meaning that they accumulate in the body instead of being broken down. PBDEs were identified as mutagens, as well as
possible carcinogens. Because of these findings, PBDEs were banned in some countries and

Dead Orca Research Paper
In 2002, a deceased female orca was discovered on Dungeness Spit in Washington. The dead orca contained 1000 parts per million (ppm) PCBs, an

Environmental Effects Of Organic Pollution And Its Effects...
Organic pollutants normally originate from numerous human activities which include manufacturing, managing storing, and disposal of chemicals.
Industrial places are a contributor of the contaminations that besiege our environment and this does not stop there as the oil refineries on their own in
some countries cause unquantifiable damages to their land and water bodies. Agricultural activities which involve use of pesticides and insecticide also
contribute, not to talk of households generally.
THE CHEMICAL INDUSTRY
This is another instance within the feel, commonly due to the fact their waste is known to pollute waste streams. In real sense, the waste discharge
from chemical industry at the moment are adequately managed and treated earlier than being launched into the environment. There were no facilities to
effect this treatment in the past and so there is a considerable level of damages which has already struck the water bodies due to this waste disposal by
industries. Even though efforts have commenced to beat to the barest minimum this sort of pollutants, its impact continues have not totally vanished.
HOUSEHOLD CHEMICALS
There are release of substances which are products of chemical organics that not only affects the environment but takes decades for it to decompose. We
use most of these products in our environment and though not many know the harms it because they are largely disastrous to the environment. There
are massive campaigns against the use of polythene bags as well as pet bottles because of the harms which their accumulation causes to the water
bodies and animals in the sea. Chemical substances which contaminate the environment would not out rightly present themselves as contaminants
because some are useful environ to man. This leads to the detergent we use in our laundry, the constituent of this detergents are not only beneficial but

In both past and present, the traces of Agent Orange have drastically affected the ecosystems of Vietnam. The causes for the effects of Agent Orange
are due to its main, and most dangerous component: Dioxin. Many of the separate Agent compounds contained dioxin, but Agent Orange contained
Tetrachlorodibenzo–p–Dioxin (TCDD,) one of the most potent forms of Dioxin. TCDD is responsible for many of the sub–lethal effects on wildlife in
Agent Orange spray zones, causing tumors and birth defects, along with a variety of cancers to animals who ingest it [HowStuffWorks Science].
Almost every living animal has small amounts of Dioxin located in their body fat, but the mutagenic effects of Dioxin occur when it enters an
ecosystem in large amounts. The body can process small amounts of dioxin, but in vast quantities, like the millions of gallons of Agent Orange
dropped on the forests of Vietnam, it is a very powerful poison. After the Dioxin soaked up into the plants and ground of the Vietnam forest it worked
its way up the food chain, as herbivores ate the Dioxin–infused grass, then become Dioxin–laced themselves, eventually everything became infected
with the Dioxin and slowly died out, eventually, all the plants and animals were gone, leaving a barren wasteland. That is how the forests of Vietnam
eventually withered away, and some did not return [HowStuffWorks Science]. This is very clearly a violation of environmental justice,

What Is Monsanto Ethical?
Monsanto is the largest seed production company in the world. Based in St. Louis, Missouri, the corporation has bought out several smaller

The Battle Of The Vietnam War

on soldier's bodies even after the war. Soldiers exposed to Agent Orange revealed similar symptoms, including; "reproduction and development
effects, depression of the immune system, severe skin conditions such as chloracne, and cancers" (Palmer, Pg.174). Soldier ray quotes "I started

Ocean Pollution
As I look out at the beautiful ocean, the silky sand and gorgeous seashells lay underneath my feet. The blue waves crashing down onto the shore.
The ocean is truly a beautiful sight to see. However, we are slowly ruining this beautiful thing because of the way we treat this planet, the ocean is
extremely polluted and marine life is paying for it. A few of the ways mankind is damaging marine life is by heavy oil pollution, and exposing
marine life to dangerous chemicals. One way our oceans are polluted is because big companies like Princesses Cruises are caught "accidentally"
dumping oil into the sea. In 2013 the Caribbean Princess Cruise Ship was caught illegally spilling 4,227 gallons of oily water off the coast of England
and records say they have been doing this since 2005 (Department of Justice) In an oil spill the majority of the oil tends to float and clump at the
surface. Which harms wildlife because mammals who hunt fish need the surface clear in order to catch their prey. In addition to that, if the oil
were to enters the water column the fish and other creatures will be greatly affected. The oil will cause reproductive damage in adult fish and will
decrease their growth drastically. Also, if the fish eggs and larvae come in contact with oil could cause death or lower their survival rate greatly.
On top of that, the most damage to wildlife is done when the oil washes on the shores because of the damaging effects it has to birds that live on or
by the shore. With birds the oil will destroy the water repealing and insulating ability that there feathers have. This leaves them to be fully exposed
to the harsh substance causing them to die of hypothermia. The oil has such a harmful effect that National Geographic said "99 percent of
rehabilitated birds will die anyway as a result of oil exposure"(National Geographic). Furthermore, the majority of the oil has been in the ocean since
2005. Usually with accidents like oil spills the government tries to clean them up as fast as possible by using dispersants and other cleaning methods.
However with the oil sitting in the ocean for years there is no telling how many birds and animals were harmed. With the government not being aware

Why Is Agent Orange Wrong

Hazardous Chemical– Agent Orange
In 1965 the United States of America became involved in the Vietnamese war attributable to the support America showed France in reclaiming Vietnam
after it became independent in 1945. The US stopped involvement in the Vietnam War in 1973. During the involvement of theUnited States, many
herbicides were used to defoliate the dense forests within Vietnam in order to upsurge their battle plan. One of the tactics of the United States was to
use what they referred to as "The Rainbow Herbicides" (Institute of Medicine, 2011). The most notorious of these chemicals was called "Agent
Orange". Agent Orange was the most popular chemical used of all the herbicides, and also the most toxic. Not only did Agent Orange cause extreme

The United States failed to perform toxicology examinations in order to determine what environmental hazards would occur by using Agent Orange.
As a result, millions have suffered from teratogens, which cause birth defects, mutagens, which damaged genetic material among many Vietnamese,
and carcinogens, which caused cell damage and cancer among both American veterans and Vietnamese. Regardless of the issue that the United States
military failed to conduct previous examination of Agent Orange, the moral issue is that United States failed to perform environmental justice, which
states that there must be equal treatment of all people involved in hazardous chemicals regardless of origin, race, or gender. Another principle the
United States failed to address is the precautionary principle, which states that when a chemical hazard is possible all precautions must take action in
order to reduce risks. Environmental justice and the precautionary principle both address a strong moral compass, and what it means to possess moral
curtesy. Equal treatment of Vietnamese and US veterans has still not been

City – 200 miles that comprise the nations largest Superfund site. Pure PCBs are oozing out of the bedrock to this day, constantly recontaminating the
river and over 300,000 pounds remain concentrated in bottom sediments of the river today. The spread of PCBs throughout the Hudson River and the
food chain, which it supports, has created one of the most extensive hazardous waste problems in the nation. Polychlorinated biphenyl's (PCBs) are a
group of synthetic oil–like chemicals (therefore insoluble in water) of the organochlorine family. Until their toxic nature was recognized and their use
was banned in the 1970s, they were widely used as insulation in electrical equipment, particularly transformers. Reputable chemists have since
concluded, "it was probably a mistake ever to make or use PCBs." These are serious poisons, which have been shown to cause damage to the
reproductive, neurological and immune systems of wildlife and humans and are known to cause cancer. Exposure has also been linked to behavioral

Many companies produced PCBs in the 1930's and 1940's and because the chemical does not decompose, PCBs are still present in soil and rivers,
subsequently ending up in fish and other wildlife. According to the Environmental Protection Agency (EPA), PCBs build up in the environment, and
larger concentrations are found higher in the food chain. Eating contaminated fish is the most likely way for PCBs to get into the human body. In
1997, the EPA banned the production of PCB's and they were classified as a probable human carcinogen.
DREDGING
Dredging is the removal of soil or material from the bottom of a river, lake or ocean harbor. (Encarta Online 8 Apr 2001). There are two distinctive
types of dredging; navigation and construction dredging, and environmental dredging. Navigation and construction dredging are used to remove
sediment that has accumulated to a level where the water depth is insufficient to support safe navigation (Huskie 2). Navigation dredging tends to use
large open clamshell dredges. Environmental dredging utilizes hydraulic dredges that act as a vacuum to remove contaminated sediments such as
PCBs, ("Environmental" Clearwater.org). A representation of these dredges is on the following page courtesy of Keene Engineering ("Environmental"

Heavy pollution can be found all across China, though it is more concentrated in the east than anywhere else. But where does all of this pollution
come from? Many people would assume that it is generated only urban or industrial areas(This is also true for air pollution); however, farmers play a
big role in polluting the water. With a fast–growing population and economy farmers are required to produce more crops every year. This has led them
into using organochlorine pesticides which was heavily used in the 1950s to the 1970s to control agricultural and get rid of mosquitoes. According to
Farmers continue to use harmful chemicals such as polychlorinated biphenyls which is used for lubrication on farming equipment such as tractors, air
compressors, pumps, and other agricultural machinery however it was later found to be harmful to the environment and cause cancer to animals

The Battle Of The Vietnam War
me may say the war in Vietnam was fought over the topic of pride; others say it was a useless war that served no purpose. Regardless of the meaning
behind it, we cannot forget the soldiers that lived through it and the hardships they faced afterwards. A soldiers hardships are felt through their body,
mind, and soul. The Vietnamese war has impacted all veterans with physical scars, emotional breakdowns, or spiritual growth; these are the three
mementos that are usually brought back from war and have everlasting effects on their everyday lives. The most common injury resulting from war, is
physical injury. Flesh wounds, amputations, diseases; these can be categorized as physical injuries. A vital contributor to these injuries is a chemical
called Agent Orange. "Agent Orange is derived from an herbi– cide called dioxin, which was used in Vietnam extensively in the areas that had
foliage." (Ybarra, Pg.126) This chemical was created with the intention of repelling insects from soldiers at war; however, it had long–standing effects
on soldier's bodies even after the war. Soldiers exposed to Agent Orange revealed similar symptoms, including; "reproduction and development
effects, depression of the immune system, severe skin conditions such as chloracne, and cancers" (Palmer, Pg.174). Soldier ray quotes "I started

The Effects Of E Waste On The Environment
E–waste is a significant issue in environmental health. Both scientists and policy makers recognize the adverse impact e–waste imposes on the
environment, and they must work together to undermine the impact. In Guiyu, which is the world's largest e–waste processing village, workers break
electronics apart, burn them, or dump them in acid baths to extract their valuable components, such as copper and gold. However, these primitive
methods, especially when done in an open space, result in air and soil pollution, as well as endangering various life forms due to the emission of toxic
chemicals into the environment. To remedy the issue, a global agreement regulating movements and disposal of hazardous wastes between countries
must be reached, for which initiatives like the Basel Convention and Basel Ban are established.
Ever since the invention of electricity in the 1800s, scientists and engineers have been developing backbone technologies for various electronic
devices today. The rapidly advancing technology of electronics raises a major concern that does not only address what devices and appliances to

The town did not have a mayor, not even a city council. The purpose of the landfill was to bury the large amount of contaminated the soil with toxic
Polychlorinated biphenyl (PCB), a class of chemicals so toxic that Congress banned production later. The whole story began in 1973 when Ward PCB
Transformers Company dumped more than 30,000 gallons of PCB–contaminated oil on the side of state roads in 14 North Carolina counties. The
trucker, who was responsible for taking the oil to a facility to be recycled, disposed of it discreetly and illegally. The person in charge of the

In both past and present, the traces of Agent Orange have drastically affected the ecosystems of Vietnam. The causes for the effects of Agent Orange
are due to its main, and most dangerous component: Dioxin. Many of the separate Agent compounds contained dioxin, but Agent Orange contained
Tetrachlorodibenzo–p–Dioxin (TCDD,) one of the most potent forms of Dioxin. TCDD is responsible for many of the sub–lethal effects on wildlife in
Agent Orange spray zones, causing tumors and birth defects, along with a variety of cancers to animals who ingest it [HowStuffWorks Science].
Almost every living animal has small amounts of Dioxin located in their body fat, but the mutagenic effects of Dioxin occur when it enters an
ecosystem in large amounts. The body can process small amounts of dioxin, but in vast quantities, like the millions of gallons of Agent Orange
dropped on the forests of Vietnam, it is a very powerful poison. After the Dioxin soaked up into the plants and ground of the Vietnam forest it worked
its way up the food chain, as herbivores ate the Dioxin–infused grass, then become Dioxin–laced themselves, eventually everything became infected
with the Dioxin and slowly died out, eventually, all the plants and animals were gone, leaving a barren wasteland. That is how the forests of Vietnam
eventually withered away, and some did not return [HowStuffWorks Science]. This is very clearly a violation of environmental justice,

A Brief Note On Pcbs And Its Effects On Human Health
Introduction
Water pollution can be potentially harmful to the environment, aquatic ecosystems, food production, and can significantly impact human health.
Polychlorinated biphenyls (PCBs) are manufactured organic compounds containing over 209 types of chlorinated chemicals (Wisconsin Department
of Health Services, 2014). Since PCBs are organic compounds, they can be degraded in the environment. PCBs can be broken down by sunlight or
biodegrade by microorganisms. However, the degrading process depends on the concentration of the PCBs. The more concentrated the compound is,
slower the process will be (National Ocean Service, 2014). PCBs were first utilized for commercial and industrial applications such as electrical
insulators, transformers, and appliances. The accumulation of PCBs increased when wastes containing PCBs from manufacturing plants were being
placed at landfills (National Ocean Service, 2014). Since the 1970s, manufacturing of PCBs have been banned from Western countries and the United
States. In recent decades, reports of PCBs have been surfacing worldwide in soil and aquatic environments (Zheng et al., 2015).
PCBs can be found all over the world especially near bodies of water. Large amounts of research concluded that pregnant females exposed to moderate
to high levels of PCBs during pregnancy can lead to problems during postnatal health. Some of these problems include lower birth weight and smaller

Da Nang Case Study

  • 1. Da Nang Case Study In 2007, Congress collected $130 million dollars to assist health issues related to Agent Orange, thus including direct care as well as research [21]. Since Agent Orange's effects range greatly from person to person based on age, exposure rate, and concentration, it is not as simple to classify as a virus or bacteria. Therefore, a cure–all for Agent Orange is not possible, treatment for the symptoms is the only way to cure those affected. Although "cleaning" where there is a greater concentration of dioxin in the environment can stop future cases of dioxin poisoning. So to protect people before Agent Orange can affect them, it must be "cleaned" by different organizations to promote the health of Vietnamese citizens. Due to all the believed health effects, the veterans of the war from the United States, New Zealand, and Australia made a case against the companies responsible for producing Agent Orange, finally reaching ...

Da Nang is an attractive city, due to the French colonial powers centered in the city during their colonial rule over Indochina, there is a fascinating cultural crash. French style bakeries are selling French desserts as well as French style cafes; French architecture influences many of the buildings. The unique history of the city has led to Da Nang to becoming a popular tourist attraction. The need for a clean and proper airport resulted from the in the influx of visitors. The problem lies with the fact that the Da Nang Airport was historically owned and operated by the United States military [25]. Thus it became a hotbed of Agent Orange contamination after the war [25]. Many of the barrels of Agent Orange were left in the area after the war instead of removing them and returning them to the United States, so some of the barrels leaked into the environment [25]. They would seep into areas like water supplies and the soil, contaminated the ... Get more on HelpWriting.net ...
  • 2. Agent Orange : Medical Ethics Motivation: Throughout the past Forty years the Vietnam war and it's after effects have shaped and changed so many individuals and their lives. I will expose a deeper look at what actually occurred during the war and most importantly what actually caused the millions and millions of lives; both Vietnamese, Japanese, and American. Problem statement: With war comes after effects and throughout the past Forty years many American Veterans from Vietnam have had health complications and issues due to the widespread use of Agent Orange during the duration of the war, especially at base camps. These ailments, cancers, and diseases can be traced back to a series of Chemical Defoliates or herbicides that have left traces of Dioxin with whoever or wherever it once was used or sprayed. Conclusions: For all of these Veterans affected by this chemical unknowingly deserve restitution and better yet compensation for their medical issues and bills. Agent Orange: Medical Ethics Agent Orange was widely used throughout the entire Vietnam war by Anti–Communist forces. In 1962, 85% of the food sources in Vietnam were targeted to be sprayed with Agent Orange from the air. Helicopters and planes were used in order to do aerial drops consistently and easily. On top of the use of Agent Orange on the forests of Vietnam, United States military bases used this herbicide daily if not weekly in order to keep the lands on the bases clean and low amounts to no vegetation on the bases.

  • 3. Polychlorinated Biphenyls: Nature and Management PCB: Nature and Management Introduction The history of PCB's (known as the Polychlorinated Biphenyls) dates back to the early 1930's. There is no record of the chemical existing in nature prior to this. This chemical substance is a type of oil that is chlorinated. It is hardly reactive with other substances. It is not even prone to rapid combustion and serves as an electrical insulator. The chemical also maintains its structural integrity when subjected to high temperature and pressure. This led the scientific community to consider PCB's as the perfect replacement for dielectric liquids and as a form of insulation within capacitors and major transformers (Forsberg, 2007). The property of PCB enabled it to be an immediate candidate for use in hydraulics, light (fluorescent) ballasts and heat transfer mediums. Its usage was further expanded to include tasks such as making pigments, plasticizers and industrial grade wax. Discussion Identification It is important for a Food safety professional to be able to detect the effects of PCB's on humans, animals and the environment. This provides them with important cures in how to contain and eventually eradicate the exposure to the PCB's. In human beings the first sign of PCB exposure and poison is chloracne and rashes on the skin. The PCB is fat soluble so it will dissolve in the dermis and any other layer than contains fat. The detection of PCB in a human source is important because it shows that there is a pre–dominant ... Get more on HelpWriting.net ...
  • 4. Retinol Hypothesis The relationship between polychlorinated biphenyls and thyroid hormones and retinol was studied focusing on two groups of female polar bears (females with cubs of the year and females without cubs) and within a group of males. PCB is an industrial organochlorine chemical by–product which has toxic effects. Since PCB is volatile it is deposited in the polar regions. PCB negatively impacts brain development due to their impact on the thyroid system. It also causes menstrual dysfunction, anovulation, and miscarriage. The polar bear feeds on the seals which contain OCs in their fatty tissues so the PCB congeners can greatly accumulate in their body. There are two main types ofThyroid hormone : T4 and T3. Retinol is vitamin A which is also affected by PCB. Retinol is a fat–soluble vitamin needed for ... Show more content on Helpwriting.net ... PCB also affects the thyroid enzymes. In this study, the global null hypothesis was there is no relationship between PCB and Thyroid hormones and Retinol in female and male bears. The alternative hypothesis was that there is a relationship present between PCB and Thyroid hormones and Retinol in female and male bears. The treatment group in the study was that the expecting polar bear mothers fasted for at least three months and the control group in the study was the mothers who were not pregnant and the males. Because intercourse, reproduction, and sustenance of the polar bears affect the level of thyroid hormone and retinol, there are likelihoods of the effects of PCBs and other OCs on thyroid hormones and retinol status may vary. The bears were all from the Svalbard population. In order to prevent confounding results occurring from seasonal variation, the study took place in spring between the months of March and April. The animals were live–captured and tranquilized by injection and the health of the polar bears was assessed and their age was determine using a vestigial premolar ... Get more on HelpWriting.net ...
  • 5. Polychlorinated Biphenyls Research Paper The substance that I decided to discuss is polychlorinated biphenyls(PCBs). The reason I chose this substance is because I never heard of it and I wanted to gain further knowledge on it. In 1865 the first PCBs similar chemical was found by a product of coal tar. PCBs is a man made chlorinated hydrocarbons and was produced in the United States for almost 50 years. It was finally banned in 1979. According to our textbook Warren County, a dominate black area had 32,000 cubic yards that was contaminated with extreme amount of toxic from polychlorinated biphenyls in 1982. PCBs were used as coolants and lubricants in electrical equipment like capacitors and transformers. PCBs prevent electrical equipment from burning as fast and are supposedly ...

  • 6. Economies Of Scale And Scope Economies of Scope: Economies of scale and scope help producers lower their cost by producing the next unit of output at lower costs this trend continues until production reaches a level of diseconomies of scale where production is no longer running as efficient as it should. This tends to increase the barriers to entry for new competitors as when they enter the market they will experience a higher cost of production. Why? Solely because they have smaller economies of scale and cannot afford to sell the product at the same price as other much larger firms. Generally, economies of scale and scope positively affect General Electric. Since General Electric is one of the biggest conglomerates in the world it has the opportunity to offer products and services through the same organization. These products might be highly unalike but due to the wide range of businesses covered by GE the prospect is there. For example, GE, in order to continue a healthy relationship with valued customers, has allowed the multimillion dollar purchase of its jet engines to be financed over long periods of time. The catch is that these finance opportunities are usually done via a leasing arrangement from GE Finance. In recent year GE has pursued a service strategy when it comes to selling aircraft engines. They sell what they call "power by the hour" this enables the private firm to indirectly rent the engine turbines, in return the firm would award GE with maintenance contracts on the engines.

( Hartig 1998) Emphasize that the contamination of any water or soil asset from critical measures of chemicals, particularly oil and poisonous metals, regardless of whether the asset is an aquifer, a waterway, a lowland, a wild rice bed or a lake, despite what is said in the purposeful publicity battles that are slyly created from the blameworthy mining, vitality or oil organizations whose defective innovation can be capable. Oil based commodities and overwhelming metals are both equipped for gliding on, blending with or sinking underneath the water therefore streaming a long way past the mouth of the stream, connecting to the shoreline or potentially sinking into the slop at the base. Point of View: The water, soil and air in the range where mechanical spills happen can be required to stay contaminated always, similarly as the dangerous metals found in coal powder tailings lakes and coal–let go plants can decimate groups as their lethal ooze and smoke harm the downstream and downwind condition. There are few places on earth that are not downwind or downstream from some dangerous industry. Rustic, non–horticultural, northern Minnesota is relatively sheltered, yet it may not be for long.

  • 8. Thesis Statement On Dioxin Dioxin is a general name for a large group of hundreds of chemical compounds with similar structure. These compounds are made up of carbon, oxygen, hydrogen and chlorine atoms. It deposits in the fatty tissue and can be a long–time danger for human and animals. My Thesis Statement is that Dioxin is one of the rogue chemical, which can have bad impacts both human– and animals health, which also can cause at worst the death. What are the inference from Dioxin? The particle model of the toxic chemical named Dioxin.

Doctors still agree: The use of the breast–feeding excels the dangers by far. Dioxins are environmental pollutants. They belong to the "dirty dozen" – a group of dangerous chemicals known as persistent organic pollutants (POPs). Dioxins are of concern because of their highly toxic potential. Experiments have shown they affect a number of organs and systems. Once dioxins enter the body, they last a long time because of their chemical stability and their ability to be absorbed by fat tissue, where they are then stored in the body. Their half–life in the body is estimated to be 7 to 11 years. In the environment, dioxins tend to accumulate in the food chain. The higher an animal is in the food chain, the higher the concentration of dioxins. Dioxin is mainly a result from natural processes, like volcanic eruptions or forest fires, etc. Dioxins are found throughout the world in the environment. The highest levels of these compounds are found in some soils, sediments and food, especially dairy products, meat, fish and shellfish. Very low levels are found in plants, water and air. High level of dioxin can be result of skin lesions, such as chloracne and patchy darkening of the skin and altered liver functions.

The EPA considers a 200 miles stretch of the historic Hudson to be one the largest Superfund sites in our nation. What was GE's environmental stance during the latter part of the 20th century? In three words Dismal, Denial, and Diswoned! Mr. Jack Welch's, reigned as Chairman and CEO of GE during the years of 1981–2001, taking over from his predecessor Reginald H. Jones. Regarding the case of GE's dumping of PCB's into the Hudson, a rather frosty Welch negotiated with the state of New York, settling to pay a mere $3 million dollars for the damage caused to the Hudson River. According to Cray (2001), "GE executives probably hoped the deal would bury the issue forever, and that everyone concerned about the PCBs (polychlorinated biphenyls) lying on the bottom of the river would let nature take its course." (Multinational Monitor, 2001) During that time Jack Welch's stance on the accusations resulted in historical comments filled with denial, Jack said, during a 60 Minutes interview, "The word 'dump' is used! We didn't dump! We had a permit from the U.S. government and the State of New York to do exactly what we did. Do you think I'd come to work in a company that would do that or condone that? I wouldn't do it, Lesley! This is nuts!"

  • 10. Environmental Impact And Sustainability Issues Related For... Environmental Impact and Sustainability Issues related to PBDEs In chapter fourteen of our textbook, Environment: The Science Behind The Stories, it is made clear that the United States does not use the precautionary principle approach when it comes to evaluating how toxic a substance is (Withgott & Laposata, 2014, p. 382). This lack of precaution has proven to be dangerous when it comes to chemicals, especially when using polybrominated diphenyl ethers (PBDEs). PBDEs are chemically engineered flame retardants used during the manufacturing process of clothing, bedding, and many other household goods. These flame retardants work by eliminating the fire's oxygen supply, resulting in less damage to the item and a decrease in the chance of a larger fire (Hester & Harrison, 2013, p. 45). While PBDEs may have been necessary during a time when there were fewer fire regulations, it is clear that the negative effects of these flame retardants outweigh the benefits in today's times. According to the journal of Environmental Science & Technology (2016), the toxicity of PBDEs was first discovered in Sweden, when a study exposed an unsafe and increasing level of flame retardants in the breast milk of women. This study showed that PBDEs were potentially toxic and highly bioaccumulative, meaning that they accumulate in the body instead of being broken down. PBDEs were identified as mutagens, as well as possible carcinogens. Because of these findings, PBDEs were banned in some countries and ... Get more on HelpWriting.net ...
  • 11. Dead Orca Research Paper In 2002, a deceased female orca was discovered on Dungeness Spit in Washington. The dead orca contained 1000 parts per million (ppm) PCBs, an estimated six times more than the average Pacific Northwest orca (1). PCBs, or polychlorinated biphenyls, are a type of manufactured chemical. Their use was predominantly within electrical equipment, acting as coolants or lubricants, along with being used in paints, cement, or other common material (2). Such chemicals are a large issue in the PNW, despite being banned decades ago. Today, killer whales are in danger of becoming extinct due topollution of substances like PCBs. Due to biomagnification, chemicals like those mentioned only magnify in populations higher on the food chain. How does this effect the orca population? Pollution at these levels are creating various health issues in the large mammals and decreasing their numbers rapidly. Equally worrisome is the fact that humans consume the same contaminated food as orcas (e.g., salmon). ... Show more content on Helpwriting.net ... Generally containing about 150 ppm, killer whales are known to have numerous issues due to these high levels of contaminants (3). Seals have been known to have immune complications when carrying less than 10 ppm PCBs (3). Hence, orcas are heavily effected, facing a shorter life expectancy, birth defects, chromosomal issues, and cancer (4). Unfortunately, salmon is one of the top contributors to the pollution in orcas, and a food source for the majority of humans. In consequence, people are at risk for the same negative effects of biomagnification as orcas. For this reason, there is often a recommended limit on seafood consumption.

  • 12. Environmental Effects Of Organic Pollution And Its Effects... Organic pollutants normally originate from numerous human activities which include manufacturing, managing storing, and disposal of chemicals. Industrial places are a contributor of the contaminations that besiege our environment and this does not stop there as the oil refineries on their own in some countries cause unquantifiable damages to their land and water bodies. Agricultural activities which involve use of pesticides and insecticide also contribute, not to talk of households generally. THE CHEMICAL INDUSTRY This is another instance within the feel, commonly due to the fact their waste is known to pollute waste streams. In real sense, the waste discharge from chemical industry at the moment are adequately managed and treated earlier than being launched into the environment. There were no facilities to effect this treatment in the past and so there is a considerable level of damages which has already struck the water bodies due to this waste disposal by industries. Even though efforts have commenced to beat to the barest minimum this sort of pollutants, its impact continues have not totally vanished. HOUSEHOLD CHEMICALS There are release of substances which are products of chemical organics that not only affects the environment but takes decades for it to decompose. We use most of these products in our environment and though not many know the harms it because they are largely disastrous to the environment. There are massive campaigns against the use of polythene bags as well as pet bottles because of the harms which their accumulation causes to the water bodies and animals in the sea. Chemical substances which contaminate the environment would not out rightly present themselves as contaminants because some are useful environ to man. This leads to the detergent we use in our laundry, the constituent of this detergents are not only beneficial but they are also in turn return devastating characteristics to land.

In both past and present, the traces of Agent Orange have drastically affected the ecosystems of Vietnam. The causes for the effects of Agent Orange are due to its main, and most dangerous component: Dioxin. Many of the separate Agent compounds contained dioxin, but Agent Orange contained Tetrachlorodibenzo–p–Dioxin (TCDD,) one of the most potent forms of Dioxin. TCDD is responsible for many of the sub–lethal effects on wildlife in Agent Orange spray zones, causing tumors and birth defects, along with a variety of cancers to animals who ingest it [HowStuffWorks Science]. Almost every living animal has small amounts of Dioxin located in their body fat, but the mutagenic effects of Dioxin occur when it enters an ecosystem in large amounts. The body can process small amounts of dioxin, but in vast quantities, like the millions of gallons of Agent Orange dropped on the forests of Vietnam, it is a very powerful poison. After the Dioxin soaked up into the plants and ground of the Vietnam forest it worked its way up the food chain, as herbivores ate the Dioxin–infused grass, then become Dioxin–laced themselves, eventually everything became infected with the Dioxin and slowly died out, eventually, all the plants and animals were gone, leaving a barren wasteland. That is how the forests of Vietnam eventually withered away, and some did not return [HowStuffWorks Science]. This is very clearly a violation of environmental justice, ...

Based in St. Louis, Missouri, the corporation has bought out several smaller companies of the same kind and introduced large scale production of genetically modified seeds for soybeans, corn, canola, and cotton. Monsanto created a chemical that could be fused with common seeds to make farmer's jobs easier. Traditional farming takes lots of manpower and hard labor. Farmers must hire people to go through fields and remove weeds and unwanted plants. Weed killers cannot be used on regular crops because the chemicals in them would harm healthy plants like corn and soybeans, either killing them, or at the least, making them unsafe for consumption.

Experiments have shown they affect a number of organs and systems. Once dioxins enter the body, they last a long time because of their chemical stability and their ability to be absorbed by fat tissue, where they are then stored in the body. Their half–life in the body is estimated to be 7 to 11 years. In the environment, dioxins tend to accumulate in the food chain.

The ocean is truly a beautiful sight to see. However, we are slowly ruining this beautiful thing because of the way we treat this planet, the ocean is extremely polluted and marine life is paying for it. A few of the ways mankind is damaging marine life is by heavy oil pollution, and exposing marine life to dangerous chemicals. One way our oceans are polluted is because big companies like Princesses Cruises are caught "accidentally" dumping oil into the sea. In 2013 the Caribbean Princess Cruise Ship was caught illegally spilling 4,227 gallons of oily water off the coast of England and records say they have been doing this since 2005 (Department of Justice) In an oil spill the majority of the oil tends to float and clump at the surface. Which harms wildlife because mammals who hunt fish need the surface clear in order to catch their prey. In addition to that, if the oil were to enters the water column the fish and other creatures will be greatly affected. The oil will cause reproductive damage in adult fish and will decrease their growth drastically. Also, if the fish eggs and larvae come in contact with oil could cause death or lower their survival rate greatly. On top of that, the most damage to wildlife is done when the oil washes on the shores because of the damaging effects it has to birds that live on or by the shore. With birds the oil will destroy the water repealing and insulating ability that there feathers have. This leaves them to be fully exposed to the harsh substance causing them to die of hypothermia. The oil has such a harmful effect that National Geographic said "99 percent of rehabilitated birds will die anyway as a result of oil exposure"(National Geographic). Furthermore, the majority of the oil has been in the ocean since 2005. Usually with accidents like oil spills the government tries to clean them up as fast as possible by using dispersants and other cleaning methods.

The purpose of the landfill was to bury the large amount of contaminated the soil with toxic Polychlorinated biphenyl (PCB), a class of chemicals so toxic that Congress banned production later. The whole story began in 1973 when Ward PCB Transformers Company dumped more than 30,000 gallons of PCB–contaminated oil on the side of state roads in 14 North Carolina counties. The trucker, who was responsible for taking the oil to a facility to be recycled, disposed of it discreetly and illegally. The person in charge of the company and the trucker was sent to jail for a short time for their negligence on the matter. Contaminants left in the truck and factory was detoxified. However, the area around the factory as well as the lakes and rivers close to the road had been polluted. As a result, more than 60,000 tons of oils were polluted with toxic PCB. Right after the pollution happened, the State of Carolina decided to erect large warming signs telling people to have cautions on the PCBs. From public's point of view, the PCBs had become a serious threat to health and soil condition. Consequently, State of Carolina found it really hard to deal with the polluted soil. A legal, long, and regulatory preparation had to be made. Finally, the state decided to landfill all the soil in the Warren County. As we can imagine people in the county would not ...

  • 35. Agent Orange : A Herbicide / Defoliant Used By The U.s.... Agent Orange was a herbicide/defoliant used by the U.S. military during the Vietnam War as part of the Herbicidal Warfare Program. Agent Orange was given its nickname due the the barrels it was stored in, marked with a single orange stripe, other herbicides used in southeast asia were given similar nicknames such as Agents Blue, Green, Pink and Purple. Despite the large veritable rainbow of different defoliants, Agent Orange was primarily used during Operation: Ranch Hand [HowStuffWorks Science]. During Operation: Ranch Hand, 19 million gallons of Agent Orange and other chemicals were sprayed over 4.5 million acres of land in Vietnam [History.com]. The reasons for the mass distribution of the chemical were to "Deny them food and... Show more content on Helpwriting.net ... In both past and present, the traces of Agent Orange have drastically affected the ecosystems of Vietnam. The causes for the effects of Agent Orange are due to its main, and most dangerous component: Dioxin. Many of the separate Agent compounds contained dioxin, but Agent Orange contained Tetrachlorodibenzo–p–Dioxin (TCDD,) one of the most potent forms of Dioxin. TCDD is responsible for many of the sub–lethal effects on wildlife in Agent Orange spray zones, causing tumors and birth defects, along with a variety of cancers to animals who ingest it [HowStuffWorks Science]. Almost every living animal has small amounts of Dioxin located in their body fat, but the mutagenic effects of Dioxin occur when it enters an ecosystem in large amounts. The body can process small amounts of dioxin, but in vast quantities, like the millions of gallons of Agent Orange dropped on the forests of Vietnam, it is a very powerful poison. After the Dioxin soaked up into the plants and ground of the Vietnam forest it worked its way up the food chain, as herbivores ate the Dioxin–infused grass, then become Dioxin–laced themselves, eventually everything became infected with the Dioxin and slowly died out, eventually, all the plants and animals were gone, leaving a barren wasteland. That is how the forests of Vietnam eventually withered away, and some did not return [HowStuffWorks Science]. This is very clearly a violation of environmental justice, ...

  • 36. Toxic Dioxins In Australia The Parramatta River is located in Sydney, New South Wales, Australia. According to the Parramatta River Catchment Group (2016), it has around 19km in length, 220km of waterways in its catchment and 257 km2 of catchment area. His estuary covers 12km2, is influenced by tidal movements, is in a constant state of flux, the freshwater from the river's tributaries change the chemical composition of the water on a daily basis and it takes 3 to 4 months to completes water exchange. The pollution of Sydney Harbour, its tributaries and catchment began when the Europeans arrived at the region, in 1788. However, was just in the XIX century, when the urbanization and industrialization processes took place of the Sydney area that most of the water contamination ... Show more content on Helpwriting.net ... 1.2.Intervention Strategies The main intervention proposes, as mentioned by Montoya(2015) to reduce the concentration of dioxins in the Parramatta River is the 2002 Environmental Impact Statement which has proposed to remediate the Unioon Carbide/Lednez site and parts of Homebush Bay, reducing the dioxins levels. But to remediate the whole Sydney Harbour, the actual strategy being adopted is to wait until the dioxin settles in the bottom of the Sydney Bay and it gets covered by sediments The dioxins are dispersed into a big area of Sydney Harbour. The main responsible processes for the spread of dioxins were the aerial deposition of dioxins that were produced as a by–product of combustion of pesticide production. Other mechanisms are the transportation of dioxins that were contained in soil sediments by the stormwater, and the dispersion of dioxins when wind–driven waves resuspended them and the spring tidal currents transported them to other locations. 1.1.Persistence Factors Dioxins are stable chemicals compounds, and persists in living beings. They can persist in the tissue of animals, and persist over the food ... Get more on HelpWriting.net ...

Polychlorinated biphenyls was used in many different things such as coolants, lubricants for transformers, and other electrical equipment. The production of polychlorinated biphenyls is stopped all together in the united states in the year of 1977 by the United States Environmental Protection Agency (EPA). The EPA did this due to the buildup of polychlorinated biphenyls found in the environment. Since Polychlorinated biphenyls have built up in our environment this means that they must have an affect on the environment. According to the EPA once polychlorinated biphenyls enter the environment it contaminates our drinking water, our food, ... Get more on HelpWriting.net ...
  • 38. A Brief Note On Pcbs And Its Effects On Human Health Introduction Water pollution can be potentially harmful to the environment, aquatic ecosystems, food production, and can significantly impact human health. Polychlorinated biphenyls (PCBs) are manufactured organic compounds containing over 209 types of chlorinated chemicals (Wisconsin Department of Health Services, 2014). Since PCBs are organic compounds, they can be degraded in the environment. PCBs can be broken down by sunlight or biodegrade by microorganisms. However, the degrading process depends on the concentration of the PCBs. The more concentrated the compound is, slower the process will be (National Ocean Service, 2014). PCBs were first utilized for commercial and industrial applications such as electrical insulators, transformers, and appliances. The accumulation of PCBs increased when wastes containing PCBs from manufacturing plants were being placed at landfills (National Ocean Service, 2014). Since the 1970s, manufacturing of PCBs have been banned from Western countries and the United States. In recent decades, reports of PCBs have been surfacing worldwide in soil and aquatic environments (Zheng et al., 2015). PCBs can be found all over the world especially near bodies of water. Large amounts of research concluded that pregnant females exposed to moderate to high levels of PCBs during pregnancy can lead to problems during postnatal health. Some of these problems include lower birth weight and smaller head circumference (Fein et al., 1984), and potentially ... Get more on HelpWriting.net ...

Many people are afraid of chemicals and their effects on them and the environment. This is understandable because the truth of the matter is that chemicals can do some horrible things to humans, animals and the whole ecosystem. Some would say that chemicals should be done away with for these reasons. But this certainly is not true and most likely impossible. Chemicals can also have some very positive effects on our lives. Some uneducated people would argue that there should not be restrictions on chemicals. This is just as crazy as saying that chemicals should be done away with. If chemicals are regulated and people abide ... Show more content on Helpwriting.net ... Some people would say that because PCB's and Dioxins cause cancer that they should be done away with. However they do not realize that this would mean giving up their electricity in their homes and their transportation. This is because every home uses a transformer to convert its electricity to a usable voltage. And without capacitors to keep the amperage and voltage in phase cars would not run properly. (1) Speaking of cars, who does not use one pretty regular? Cars, buses, trucks, planes, construction equipment, all run on combustion engines. A combustion engine must be fueled by some type of fossil fuel. When a fossil fuel is burned it releases many chemicals some which are likely pathogens such as, Carbon Monoxide, Nitrogen Dioxide, Sulfur Dioxide, PM–10, Benzene, Formaldehyde, Polyeyche Hydrocarbons. The direct benefits of these chemicals may be hard to see however they are a necessary if we intend to keep on using our cars (Environmed Research Inc. 2).

  • 40. Military Nerve Agents Nerve Agents are defined is a class of chemicals put together depending on their similar mechanism of action. Nerve agents interrupt vital nerve communication in various organs. The severity of reaction depends on the range of toxicity and dosage released. The most well known military nerve agents are tabun, sarin, soman, GF, and VX. All of these are manmade compounds. The first military nerve agent GA (ethyl–N–dimethyl–phosphoroamidocynate) was discovered in Germany. After this discovery it was weaponized along with GB (sarine) and GD (soman) together creating the "G–series". England then found approximately 4 years later the V–series including VX.
