Great Smog Of London And The Scientific Implications In...
The Great Smog of London and the Scientific Implications in Today's World
Turn of the century London, the emergence of the middle class has forced the cultural bias to shift in favor of more homes, more people, and a lot of
energy consumption. Science's solution to the energy crisis is a seemingly perfect one: distribute and utilize a more available fuel. Coal burned
slower than wood and therefore kept people and homes warm more resourcefully. For a while it seemed like a miracle solution. The industrialization
of the previous age had been using coal as well, and when the air became polluted with the factory and energy refuse, the smog was swept away in a
matter of hours (Kilen, C.) That went on until early winter of 1952. That fall had been an unusually cold one, and the coal had been burning day and
night. The factories had been chugging on, and the black smoke kept rolling. The process by which factories burn coal is as follows: the coal is
blown into the furnace where it burns while still airborne. The heat is used to warm water, which then produces steam, which spines a turbine. The
factories that burn coal now use methods to slightly lessen the pollution, such as wet limestone to absorb the sulfur (How Coal Works, Union of
Concerned Scientists, p.4). This particular winter, though, the pollutants would not be swept away as they had been in the past. This is due to the fact
that on this particularly cold December, an inversion occurred over the city of London. An

Groundwater Lab Analysis
Groundwater samples will be analyzed using the methods presented at the top of Table 1. EPA approved instrumentation methods will be used in the
standard analysis of VOCs (Method 8260), total metals (Method 7470 for Mercury and Method 6010 for all other PP metals), and SVOCs (Method
8270) which are published by EPA and routinely performed by most commercial laboratories. These methods with associated instruments, and method
detection limits (MDL), and sample hold times are briefly summarized as follows: 8260: Analysis of volatile organic compounds by gas
chromatography and mass spectrometry (GC–MS); MDL for VOCs generally less than 1 ppb – see method [8]; Hold time = 14 days. 6010: Inductively

One particularly sensitive method for analysis of pure solvent (applicable to wells containing DNAPL) involves combustion of the chlorinated
hydrocarbon sample with CuO, precipitation of AgCl and formation of CH3Cl for analysis on IRMS [10]. Isotopic ratios are expressed in the delta
notation, Оґ, which represents the per mil variation of the isotopic ratio standard. For carbon, the 13C/12C ratio is established by the Pee Dee
Belemnite international standard and 37Cl/35Cl ratio is compared to the Standard Mean Ocean Chloride (SMOC) standard by the following equation:
Оґ13C or Оґ37Cl = (Rsample/Rstandard – 1) * 1000. Comparison of the deltas for both compounds as part of a multi–isotopic approach will provide
greater confidence in the determination of the plume source by providing a more fine–tuned view of chlorinated solvent signatures compared to single
isotope analysis, particularly under consideration that Оґ37Cl values are typically within a much smaller range than that of Оґ13C.
Laboratory Quality Control
The laboratory will utilize a variety of quality control sample types as shown in Table 3. Matrix spikes and matrix spikes duplicates will be performed
on field samples that are provided with sufficient volume (generally three times original sample volume). All other blanks, duplicates and control
samples will originate in the laboratory and be performed to ensure accuracy of the analytical method, equipment and procedures. These

The Importance Of Drinking Water In Bangladesh
Introduction
Safe drinking–water is essential for healthy life, and United Nations (UN) General Assembly declared safe and clean drinking–water as a human right
essential to the full enjoyment of life [1]. Moreover, the importance of water, sanitation and hygiene for health and development has been reflected in
the outcomes of a series of international policy forums [1]. These have also included health and water–oriented conferences, but most importantly in the
Millennium Development Goals (MDG) adopted by the General Assembly of the UN in 2000. The UN General Assembly declared the period from
2005 to 2015 as the International Decade for Action, "Water for Life" [1]. Access to safe drinking–water is important as a health and development
issue at national, regional and local levels. Bangladesh, a developing country from South Asian (SA) region also takes several steps for ensuring
sanitation and safe drinking water facilities among the people. As a result, Bangladesh has made great progress in this sector. The government also
claimed that it has achieved the MDG indicator of ensuring safe drinking water for 85% people of the country. According to different demographic
and health surveys, the percentage of using improved sources of drinking water is about 98% (reported in the latest two surveys Multiple Indicator
Cluster Surveys (MICS) 2012–13 and Bangladesh Demographic and Health Survey (BDHS) 2014) [2,3]. But, this achievement statistics are
overlooking the shortcomings.

Volatile Aromatic Organic Compounds
1. Introduction The release of volatile aromatic organic compounds into the environment is a serious problem as they distribute between the different
phases in natural systems. Sediments can be considered as a sink for volatile aromatic organic compounds because of their hydrophobic nature and the
resulting affinity to the sediment 's organic matter. Organic matter consists of soft carbon, where portioning is the main sorption process and hard
carbon, where pore filling mechanisms dominate (Zhao et al., 2002; Chai et al., 2006). Consequently, sorption/desorption processes are the most
important factors that determine the fate of volatile aromatic organic compounds in the environment. The extensive production and release of aromatic
organic compounds has led to a widespread contamination of soils and sediments with these pollutants throughout the world, threatening drinking water
resources, especially petroleum hydrocarbons as constituents of gasoline such as Benzene, 1,2 dichlorobenzene, Toluene and m–xylene. It was
proposed that sorption of the sorbate molecules may cause deformation of flexible sorbent solids, such as natural organic matter and organo–clays
resulting in an entrapment of sorbed molecules during desorption (Weber et al., 2002; Lu and Pignatello, 2004). Several researchers have tried to
associate the maximum sorption capacities of organic compounds with the sorbed amounts in the slow and very slow desorbing domains (Van Heuvel
et al., 2005; Van Heuvel and

A Research Study On Bpa
1). INTRODUCTION/ SPECIFIC AIMS, BACKGROUND AND SIGNIFICANCE.
Alexander Dianin was a Russian chemist who first compounded Bisphenol A, during the year 1891. Bisphenol A is commonly referred to as BPA.
Dianin was carrying out studies on phenol compounds and synthesized BPA by condensing acetone with two equivalent parts ofphenol. The "A" in
BPA denotes acetone in its composition. (1)
At first, the development of BPA was solely an academic exercise. Dianin was the chair of theChemistry Department / Imperial Medial Academy in
St. Petersburg, Russia. (2) Modern organic chemistry was in its beginning phases and the potential benefits from combining organic compounds were
being envisioned. Reports of BPA synthesis was first published in Eastern European chemistry journals and eventually appeared in Western journals.
For decades, BPA was referred to only as: "Dianin's Compound." (3) By today's organic chemistry standards, BPA is a relatively simple molecule and
is easy to produce industrially. However, in 1891, BPA's synthesis was a remarkable discovery. BPA's laboratory synthesis demonstrated that the
simplest member of the ketone group, acetone, could be combined with two molecules of phenol. The result was a previously nonexistent artificial
compound. (4) Contrary to inorganic chemistry, this was not single elements reacting to form a relatively small compound; organic chemistry had the
potential of combining many more compounds with seemingly unlimited potential of

Groundwater Groundwater Pollution
Groundwater Pollution with Chlorinated Ethenes Groundwater is water that is located underground between soil particles and in holes, or pores, in the
bedrock ("Groundwater," 2011). Because earth has 80 times more groundwater than all the freshwater stored in lakes and streams combined
("Groundwater," 2011), its health has a large influence on the environment. Groundwater also has a large impact on humans; groundwater accounts for
about 20% of water used in the US and almost half of water used in households, including drinking water ("Groundwater," 2011).
Chlorinated ethenes, also referred to as organochlorides, CVOCs, and chloroethenes, are common groundwater contaminants throughout the world
(Zinder & Gossett, 1995; Dugat–Bony, et al., 2012; Rouzeau–Szynalski, Maillard, & Holliger, 2010; Ni et al., & Rijnaarts, 2014). They are often found
in various environmental media near industrial facilities (DobrzyВґnska, PoВґsniak, SzewczyВґnska, & Buszewski, 2010). Chloroethenes tend to be
persistent in the contaminated groundwater; they remain present indefinitely and are usually not degraded through natural means by any indigenous
population (Zaan, et al., 2009; Tas, 2010).
Chloroethenes tetrachloroethene (PCE) and trichloroethene (TCE) are the most common type of groundwater pollutant in urban and industrial areas
and pose a threat to human health (Lee & Lee, 2016). Both PCE and TCE concentrations are regulated by the 1986 amendments to the Safe Drinking
Water Actdue to

Z6 House Case Study
All rooms in Z6 house receive plenty of light since the building envelope is 73% (area) glazing. A big window can let in plenty of outdoor air and
sunshine to stop the growth of bacteria. In Z6 house, skylights will bring light into the two bathrooms in the upstairs. The southwest, southeast, and
northeast exterior have operable windows and doors, while the northwest facade has a translucent insulated panel for daylight transmission in a
direction without desirable views. Scientists discovered daylight through glass could stop the growth of bacteria. There is a research highlighted that
how day lighting can significantly increase human health and performance.
We spend almost 90 per cent of times in our homes, which mean we inhale huge amount of indoor air, so it is very easy to see how indoor air
quality impact our health. According to the research carried out by Steven E. Ternoey which titled "Day light Every Building", there are many
benefits that human can gain from day light especially in the indoor. From the research, we know that there were noticeably less disciplinary
problems and absenteeism in day lit classrooms. Students show positive attitude and easier to focus in the class. In day lit areas, retail sales
increases of 8 to 12% were recorded. Human health appears to be measurably benefited by relatively small indoor doses of diffuse daylight. Our body
need vitamin D and absorbing of sunlight helps in the making of vitamin D in our body. If we do not get enough day

Title: Volatile Organic Compound detection using Graphene: Determining the Fruit Ripeness
1Introduction
Fruits are commercially vital and nutritionally crucial food constituent. Forming an element of a balanced diet, fruits supply essential growth governing
factors required for good health and play a critical role in human nutrition. Distributed widely in nature, their economic values are influenced by–
comparatively short ripening period and short post–harvest life. The assessment and maintenance of the quality of fruits and vegetables are very

difficult task. The timely detection of fruit ripeness is very important as it is related to the profitability and also competitiveness of the producers as
well as processors. During harvesting and handling it is common that fruits are subject to damage because it is not possible always to

These contaminations of the areas were discovered in 1981. The public wells draws water from Olean creek, and they were constructed in the 1970s
to relieve the situation of water shortage for a surface water treatment plant. However, excessive leaves of trichloroethylene (TCE) were discovered in
public wells in late 1980, and so the use of the wells was discontinued. Some suspected contaminations have been identified. After a supplemental RI/FS
study to investigated thirteen properties for the presence of contamination at four of the properties as the main sources of VOC and TCE contamination

Site history
There have three public water supply wells were constructed in the late 1970s to provide water for the city of Olean, New York. In 1981, these wells
were found to contain trichloroethylene (TCE) and other chlorinated organic solvents at concentrations exceeding federal maximum contaminant levers
(MCLs). As a result, these wells were closed. Then the site was included on the National Interim priorities list on the first NPL on September 9, 1983.
Between 1981 and 1985, some separate federal–, state– and PRP–led investigations were conducted to find the sources of the contamination to the
ground water and evaluate the nature and extent of groundwater contamination at the site.
On September 24, 1985, the first operable unit ROD for the site issued by the EPA was documented. These including: 1) installation of

Volatile Organic Compounds
Overview
The Edwards Air Force Base located in Antelope Valley in Southern California was built to test new aircraft and help integrate them into the U.S. Air
Force. The site became a flight test center after World War II. As an air base, many chemicals and fuel are stored here and throughout its history there
have been spills and improper disposals. This became an environmental hazard when the contaminants began to seep into the ground. The EPA, the Air
Force, and two state agencies signed a Federal Facility Agreement in 1990 to address this issue.
Activities That Led to Pollution
The activities that led to the pollution were the storage of fuel, Volatile Organic Compounds, metals, and other chemicals. Years of flight testing and

VOCs can easily become vapors or gasses making it very toxic to any in the area who inhale it. Perchlorate, which came from the many years of
rocket fuel resting, 1, 4–dioxane, and various metals are non–volatile contaminants found in some areas. N–Nitrosodimethylamine (NDMA) is a semi
volatile organic compound suspected of being a carcinogen and is a known hepatotoxin. Some of the less harmful contaminants include landfills that
may contain unexploded artillery, weapons or other munitions related materials. Perfluorinated Compounds (PFCs), an unregulated group of chemicals,
has also been found and is being investigated at different sites on the base.
Harmful Effects
Trichloroethene has been associated with hepatotoxicity. Exposure also produces decreased appetite, gastrointestinal irritation, headaches, skin
irritation. Chronic exposure produces ataxia (loss of full control of bodily movements.), decreased appetite, headache, short–term memory loss, sleep
disturbances, and vertigo.
Tetrachloroethene is a group 2A carcinogen. This means that it is likely a probable carcinogen. It is also a Central Nervous System depressant and due
to its fat solubility it can enter through the skin and cause irritation. Acute exposure to tetrachloroethylene can cause incoordination drowsiness,
dizziness, and headaches. Large doses, however, can cause unconsciousness and death. Chronic exposure can cause changes in reaction time, memory,
attention and vision, and

Design The Earth Sciences Building At The University Of...
In 2009, Perkins + Will was commissioned to design the Earth Sciences Building (ESB) at the University of British Columbia. ESB is designed to
develop the growing relations between the Department of Earth, Ocean and Atmosphere, the Department of Statistics, the Pacific Institute for the
Mathematical Sciences, the Dean of Science and the Pacific Museum of the Earth, providing important chances for shared learning and partnership.
Placed along Main Mall, the primary north–south pedestrian route on campus, the building provides opportunity to add visual interest to the
pedestrian experience by displaying the research inside the building; to achieve this, the ground floor is considered the main public space, and is
glazed on all sides to maximize visibility into the building. Situated across the street is the Beaty Biodiversity Museum, which along with the ESB
creates a 'museum precinct' in this area of the campus. Also, to promote the project goal of 'science on display', a double–height research lab area
operates as a backdrop to integrate exhibits from the Pacific Museum of the Earth. The building contains faculty and staff offices for each department,
research laboratories, three lecture theatres, and a cafГ©. A five–storey atrium divides the north and south wings of the building, providing an
organized structure for the departments while simultaneously creating an east–west pedestrian route directly through the building. Unlike the concrete

Environmental Effects Of Air Pollution
Chemical compounds used in cleaning products and industrial production are being used every day. Some of these chemicals are naturally occurring
but others are synthetic and can cause harm to the environment and human population, by being released into the atmosphere. The ever–changing
atmosphere, especially in Pittsburgh, is filled with different compounds. Many of the compounds found in air are naturally occurring but some of these
compounds such as Titanium tetrachloride, Vinyl Chloride, and Benzene are emitted from factories and some household items and cause health and
environmental effects. Possible solutions to reduce and possibly eliminate exposure are then be explored.
To provide context on the degree of severity of the air pollution in the city of Pittsburgh now, the past must be evaluated. Since the days of the coal
plants, the city of Pittsburgh has had air pollution. The air of Pittsburgh in the nineteenth and twentieth century was enveloped with heavy pollution to
the point where visibility was hindered (Davidson, 1979, p.1035). According to Davidson (1979) back in the day, "coal from the Pittsburgh seam
[contained] 31–41% volatile compounds" (p.1036). This statistic means that 31–41% of the compounds in the coal seam would readily release into the
air with the extraction of the coal. The class of compounds inside of the coal is called volatile organic compounds, or VOC's for short (Schweinfurth,
2016). VOC's are compounds that interact with organic

Tiny House Movement
Buying a home is one of the biggest milestones a person can accomplish, and in the American society, bigger is usually better. With larger homes, there
is a certain sense of prestige and wealth that comes along with them. Unfortunately, what home buyers do not tend to know, is just how bad that home
is to not only their health, but to the environment and their wallets as well. That is why, over these past few years, there has been a significant shift to
what is known as the Tiny House Movement. However, before we embark on the tale that is the Tiny House Movement, we first must understand the
traditional home. As of 2015, the average home in America was about 2,600 square feet, and would cost generally anywhere between one–third to a
half of any given pay. At those numbers, it takes on average fifteen years to pay off the home which leaves about 76% of Americans living paycheck
to paycheck just keep a roof over their heads (The Tiny Life).
While it easy to only focus on the cost of the home, it is incredibly important to consider just want that house is doing to the environment. If we take a

The Combustion Of Household Fuels
The Combustion of Household Fuels
Introduction
Fire, from humans' first interactions with it, has been terrifying, delighting, and mysterious all at once. Yet it is impossible to imagine a day passing
without any interactions with the phenomenon. From burning wood in the fireplace, to preparing tea on a stove operating with natural gas, to using
charcoal for a backyard barbecue, different objects are chosen as the source of combustion depending on the task that they need to accomplish.
Furthermore, with parents, teachers, and firefighters incessantly warning students not to place certain substances close to nearby ignition sources, one
cannot help but wonder how the chemical characteristics of these substances play a role in determining ... Show more content on Helpwriting.net ...
Further experiments would then need to be performed to gain a complete understanding of the benefits and consequences of combusting certain fuels.
Background Information
The combustion of the hydrocarbons and organic molecules found in fuels is a chemical reaction that primarily involves the oxidation of carbon and
hydrogen in various compounds to release heat and produce water and carbon dioxide. When the environment lacks sufficient oxygen, rendering
oxygen as the limiting reagent in the reaction, incomplete combustion would occur. This involves the production of other chemicals such as carbon
monoxide and solid carbon in addition to water and carbon dioxide. The general chemical equations for the incomplete and complete combustion of
hydrocarbons are as follows:
Complete: CxHy + O2(g) в†’ H2O(l) + CO2(g)
Incomplete: CxHy + O2(g) в†’ H2O(l) + CO2(g) + CO(g) + C(s)
Of course, the composition of each fuel varies, yet the main organic molecule they contain can be used to formulate the basic chemical reaction that is
undergone when each substance is combusted. In the case with fondue fuel, methanol is the main substance that is responsible for combustion and can
be represented with the following equation (NIST 2015):
2 CH3OH(l) + 3 O2(g) в†’ 2 CO2(g) + 4 H2O(l),where is –725.7 kJ/mol

The ozone should always stay in tact to protects the earth from UV radiation, which is harmful to humans (skin cancer) and also the earth (global
warming). If allowed to build up indoors, VOCs often contribute to lightheadedness, headaches, allergies and more importantly has also scientifically
proven harmful to asthma sufferers. As a matter of fact, according to Professor Roy Harrison, professor of environmental health at Birmingham
University, there is a body of research on VOCs in the indoor environment which links them with those kinds of symptoms– headaches and not feeling
so good (news.bbc.co.uk). After proven to have negative effects on the ozone layer as well as humans, the production of CFCs was shut down and in
fact it's banned in the US. Some scientists were not convinced by the act of banning CFCs in spite of all these evidences. "Given the large economic
impact of a ban – it was estimated that industries relying on CFC production generated $8 billion in business and employed 200,000 people in 1974 –
several scientists in the field advocated waiting a few years for science to make more progress on the issue before making any policy decisions."

In the history, the first conception of materials appeared in 1865. It was a book named "Prehistoric Times" (by John Lubbock). And also, he mentioned
three–age system in material history. They are The Stone Age, The Bronze Age and The Iron Age respectively. The reason why archaeologists called
these durations those name is the people who live in that period used different kinds of materials to make different generation of tools. According to
John's book, The Stone Age is divided into Beginning Of The Stone Age and End Of The Stone Age.[14] (Source– ?) The oldest evidence of stone tool

What is a Volatile Organic Compound?
Research Questions
What are VOCs? Describe their uses and hazards. Include the properties that make these compounds hazardous. Include an image of one such
compond. VOC's stand for "Volatile Organic Compounds" and are carbon–based chemicals. These compounds include hydrocarbons, partially oxidized
hydrocarbons, and organic compounds. They are emitted as gases from specifc solids and liquids. VOC's are used in a number of household and
industry products, for examplle; fuels (propane/gasoline), paint thinners, pesticides, cleaning supplies, correction fluids, permanent markers, etc. We
are exposed to VOC emissions in our every day life and this can be very harmful to the environment and our health. One main property of VOC's is
that they have low boiling and melting points. VOC's evaporate rapidly at room temperature allowing the molecule to break apart very easily. This
property makes the compound very hazardous. The gases these compounds emit gets released into the air we breathe and contribute to many health
effects depending on the quantity present in the atmosphere. Some health effects include; eye, nose, and throat infections, headaches, nausea, and
damages to the liver and kidney. Some VOC emissions also act as a greenhouse gas and contributes to global warming.

Environmental Effects Of Plastic Pollution
Plastic pollution is all over this world. People purchase plastic almost everyday, even if someone does not realize they are purchasing this synthetic
product, most of the time the item's packaging is made of plastic. Even cleaning products and clothes contain plastic. When plastic was man–made the
only thought was the benefits it can create, the deficits were not thought of. Humans and animals are being physically harmed by hazardous chemicals
inside plastic and sadly, fifty percent of plastic is hazardous. The environment as well is being affected with pollution because of the amount of
resources that are taken and used. Many authors have researched the effects of the plastic we use daily. ZHigui He's article "Pollution characteristics
and health risk assessment of volatile organic compounds emitted from different plastic solid waste recycling workshops" researches the various
volatile compounds found in different recycling shops that lead to health risks. Charles Talsness' article is explaining the health risks of the
components found in plastic on humans and animals. Along with the article written by Chelsea Rochman, assistant professor, that classifies plastic
waste as hazardous as well and W.C. Li's article focuses on the effects of the plastic waste in the marine environment. All the while, Robert LeBlanc

Organic Compound
Inorganic and organic compounds are both necessary for the human body. The definition of an inorganic compound is a compound that does not
contain hydrocarbon groups. An inorganic compound is composed of several other elements, such as salts, metals, and other elemental compounds, but
can contain hydrogen or carbon. If they have both, carbon and hydrogen molecules, they are organic. Organic compounds are defined as compounds
containing hydrocarbon groups. Organic compounds will include things like the nucleic acids, found in DNA, lipids and fatty acids found in the cells
of living organisms, proteins and enzymes that are necessary for cellular processes to take place, and more. There are numerous effects to the body if
there are disturbances ... Show more content on Helpwriting.net ...
Hypervolemia, hypovolemia, overhydration, and dehydration are four examples of disturbances in water balance. Hypervolemia is an upsurge of
too much blood plasma, causing an elevated volume of blood. Hypovolemia is a decrease in the volume of blood in your body, which can be due
to blood loss or loss of body fluids. Overhydration is an excess of water in the body, while dehydration is a deficiency of water in the body.
Electrolytes are important minerals stored in very small amounts in the body, which include: sodium, calcium, magnesium, and potassium. An
electrolyte disturbance can be caused by severe fluid loss through sweating and by certain health conditions, such as kidney problems, diabetes,
malnutrition, hormone disorders, and heart disease. Some consequences of an electrolyte disturbance are dizziness, nausea, fatigue, or muscle
twitching or spasms that continue. The carbohydrates in foods are long chains of simple sugar molecules and must be broken down. If an enzyme
needed to process a certain sugar is missing, the sugar can accumulate in the body, causing glycogen storage diseases. Glycogen storage diseases are
caused by lack of an enzyme needed to change glucose into glycogen and break down glycogen into

A Native Conformation Of Protein And Aggregation Of Proteins
A native conformation of protein is only marginally stable than unfolded states, and most of proteins are prone to aggregate in liquid state to form
non–native supra structures. The loss of unique globular structures and aggregation of proteins are problematic in biopharmaceutical formulations due
to the reduction of therapeutic potency and the possibility of inducing undesired immune responses[1]. For several decades, it has been pursued to
develop formulation methods of preserving the protein stability. One of effective way to improve protein stability is mixing cosolvents in protein–water
system[2, 3]. The present of excipient molecules such as salts, carbohydrates, amino acids, and surfactants change the equilibrium of protein
denaturation and aggregation[4–10]. A great interest has been raised in understanding of the effects of excipients on proteins in an effort to find ideal
formulation recipes[11].
One of fundamental concept in addressing the impact of excipients on proteins is their preferential interactions in the system[12–16]. The interactions
of additives can be attractive or repellent to proteins, resulting the concentration of cosolvents in the local domain near proteins differs from that in the
bulk solution. Such a discrete population of cosolvents influences the thermodynamic properties of the protein inducing a significant change in
conformational or colloidal stability. A key parameter to quantify the preferential behavior of excipients is the

The Gas And Natural Gas
With reserves in 31 states, the US has a supply of natural gas large enough to provide the country with energy for decades ("Gas Drilling: The Story
So Far"). Access to these vast deposits is helping to significantly decrease the United States' reliance on foreign energy, as we have recently become the
largest natural gas producer worldwide ("Hydraulic Fracturing Natural Gas and Oil Development"). In addition to abundance, natural gas has several
other benefits as well. Natural gas emits only half as much carbon dioxide when burned than coal does, and currently the cost per unit is only one
third that of oil, giving it some clear advantages over other widely used fossil fuels (Harvey, Hal). As stated by chairman of BP Capital T. Boone...

Many of the additives on this list are known toxins, carcinogens, and volatile organic compounds that are recognized for their ability to cause harm in
the human body (Lustgarten, Abraham). Colborn and her co–authors went a step further to evaluate every chemical on the list in terms of health
effects, and the results were alarming. Although the effects were detrimental across the board, Colborn found 71 chemicals that were associated with
causing harm in 10 or more areas, including the central nervous system, cardiovascular system, and reproductive systems. What is even more
concerning is that companies find a way to justify their use of harmful substances by claiming that they make up only a small fraction of the injected
fluid; less than one percent. However, experts like Colborn believe that even a seemingly small percentage translates to tens of thousands of gallons of
these chemicals being pumped underground, and their research shows that even very low doses of the compounds can cause significant damage
(Lustgarten, Abraham). One of the most prominent concerns regarding the toxicity of chemical additives lies in the threat of groundwater
contamination. Although a 2004 EPA study concluded that fracking poses no threat to drinking water, the rising

The problem itself is not one that can be fixed in a few nights, what has been done to the spheres is almost irreversible with a few exceptions. The
severity of this problem isn't one that can completely alter the way we live but at the same time every action has an equal opposite reaction. Due to
the frequency of the emissions the spheres can be greatly impacted. Many people have been affected by these emissions and most of the illnesses
given to these people are very damaging or terminal. On average every 3–7 years a building is repainted and depending on the size of the building
many VOCs are released. As well as the frequent times the inside of the buildings are repainted and just creating artwork. Also VOC emissions are two

I found that the VOC free paint though more expensive still worked as regular paint would. Another downfall to buying the VOC free paint was
there wasn't as many color options because VOC free paint is not as popular as regular paint so this made my project more challenging in finding the
right colors and being able to mix them. Whereas if it was just regular acrylic paint I would be able to buy just the regular colors without having to mix
as much as the VOC free paint. So all–in–all the VOC free paint did its job not polluting the environment but it was more expensive than regular
acrylic paint. And acrylic paint by itself is already expensive, so I would not recommend buying VOC acrylic paint to just use and instead use an air

My Passion For Organic Chemistry
When I was six, I distinctly remember that my grandfather was diagnosed having an early stage colorectal cancer. He went through a major surgery
and recovered with prescription drugs and herbal therapies, which appeared to have a positive additive effect. I was inspired by the ability of the
pharmaceuticals in relieving my grandfather's pain, giving him a future, and allowing me to share more memories with him. My passion in studying
organic chemistry arises from me realizing there is immense potential embedded in the chemistry principles to develop tools for the treatment of human
diseases. Through my undergraduate studies and research, I became determined in pursuing a graduate carrier, in which I aim to grow into an expert in
chemical reactivities and an independent scientist who can invent chemistry and contribute to the development of pharmaceuticals.
In my sophomore year, I was intensely drawn to organic chemistry in Professor Thomas Maimone's class. The elegant and logical framework of
chemical transformations absorbed me. I learned the fundamental roles of organic chemistry in drug discovery and became increasingly interested in
solving challenging synthetic problems. I enjoyed the thrill of composing creative pathways to generate complexity, but also found that my knowledge
of organic transformations made me limited. Therefore, I fostered my chemical intuition on how and why reactions occur through select graduate–level
organic chemistry coursework.

Plant Kinship In Plants
"Plants are boring." That has been the belief of mankind for generations. Animals are obviously highly complex creatures with complex organ
systems, and even more intricate organs like the brain. The animal brain is able to sense surroundings, detect eminent danger, form relationships with
other animals, and recognize families. However, even without a brain, plants are capable of all this and more. For example, Parasitic plants such as
the Dionaea muscipula are able to sense and trap their prey, the Mimosa pudica has the ability to sense touch and wilt, and plants like the Cuscuta
Pentagona can sense volatile organic compounds (VOCs) from tomato plants to form a parasitic relationship (Biedrzycki M et al. 2010). Furthermore,
some positive ways that plants exhibit communication includes kinship. As children, humans are taught to share their toys and food with their siblings.
Plants it seems, have the same concept to ensure optimal growth and survival, as they act selflessly towards their relatives, share resources, and exhibit
less competition and more cooperation with their kin. Plants are able to recognize fellow kin through responses to VOCs from relatives, and perform
acts of altruism to kin by resource partitioning amongst siblings through root allocation (Karban R et al. 2013). The current research on plant kinship
and areas of future research will be discussed, as well the controversies surrounding this subject. Despite the debate on plant kinship,

Organic Chemistry Assignment : Organic Chemical Compounds
Organic Chemistry Assignment
By: Shirelle Cogan
1a) Organic compounds: C3H4, C8H10, CH3CH2CH2CH3, Benzene Inorganic compounds: H2CO2 (aq), CO2
Why? We know that organic compounds always contain carbon bonds with hydrogen, but not all molecules containing carbon are organic. They can be
carbon hydrogen bonds, carbides and carbonates.
b) C6H10= alkene, Name: 1,2–hexdiene
C3H4= alkene, Name= 1,3–propdiene
CH3CH2CH2CH3= alkane, Name= Butane
Benzene= aromatic substance, Formula= C6H6
C) I would expect 1,2–hexdiene and 1,2–propdiene to be the most reactive elements due to the fact that they include double bonds. These are more
reactive than single bonds because single bonds only have one electron being "shared" rather than two. The more electrons being fought over, the more
"aggressive" the bond is meaning is unstable and very reactive. Butane would not be very reactive due to the fact that it is made op of only single bonds
meaning that there is not as much fighting/ aggression between two atoms therefore causing it to be more stable. Additionally, in benzene (a
cycloalkene), because the double bonds are continuous throughout the ring, they are evenly distributed throughout the molecule creating a stronger
bond and lower reactivity.

Reducing Voc Emissions Are Twofold : Environmental...
1INTRODUCTION
During loading of oil tankers, Volatile Organic Compounds (VOC) are emitted to the atmosphere together with the inert gas from the upstream pipe
lines and the cargo tanks where vapour balancing doesn't exist. The cargo tank atmosphere initially contains nitrogen, CO2, other non methane
compounds, and possibly VOC from previous cargo, but during loading hydrocarbon gases (methane–pentane and heavier components) are released
from the cargo. VOC is generated by the flashing of the cargo in the piping system from the source to the cargo tanks, and from theevaporation of VOC
from the oil surface inside the cargo oil tanks. The reasons for reducing VOC emissions are twofold: environmental protection and cost reduction by
minimizing product losses.
2LEGISLATION, REGULATIONS AND MANDATORY GUIDELINES
IMO has published technical information on system and operation guidelines to assist in the development of VOC Management Plans in MEPC.1
/Circ.680 (27 July 2009) – resolution MEPC.185(59), that came in to effect on 1 July 2010. The purpose of the VOC management plan is to ensure

What are Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD)?
Biochemical oxygen demand (BOD); is the measure of the amount of oxygen consumed by aquatic life. Furthermore, is the measure that is used to
determine the level of organic pollution in a water body or is the amount of oxygen consumed by bacteria in the decomposition (oxidation) of organic
material. As the high levels of the (BOD), the higher levels of the water pollution and less (DO) levels.
The chemical oxygen demand (COD); is the measure of the all chemicals that found in the water body that can be oxidized or is the measure of the
oxygen equivalent of the organic substance found in the water body that is disposed to oxidation. The COD can be related empirically to BOD,
organic carbon, or organic matter. In COD test a chemical used instead of the bacteria to oxidase the organic substance and is used more for industrial
wastewater as the BOD is used for municipal wastewater. BOD and COD are two of three methods used to determine carbon present in the water

Emission-Excitation Matrices
INTRODUCTION
Emission–Excitation Matrices (EEMs) are three–dimensional fluorescence data that provide information about the composition of fluorescent chemical
mixtures. They constitute optical landscapes that extend over the dimensions of excitation and emission wavelengths {О»ex–О»em}, and where
fluorophores appear in the form of peaks. In the field of marine and freshwater biogeochemistry, EEMs have been used for the study of dissolved
organic matter (DOM), being a comprehensive analytical technique with which to characterise a highly complex mixture of organic compounds
(Hudson2006, Fellman2010, Nebbioso2013). Indeed, EEMs have served to advance scientific knowledge about the ecology and biogeochemistry of
DOM in aquatic systems [1,2]. Most importantly, they have contributed to evidence that some fractions of DOM are highly reactive organic molecules
that are involved in numerous ecosystem processes, such as bacterial uptake [3–5], metal binding [6,7][1,2][1,2], photoreactivity [8–10] and light
attenuation [11]. Overall these findings suggest the major involvement of DOM in the global carbon cycle [12,13].
Despite the great potential for EEMs to increase knowledge about DOM behaviour in the environment, their interpretation and statistical treatment
remain a challenge [14]. The spectral shapes of EEMs are complex mixtures of multiple and overlapping independent fluorescence phenomena, caused
by the wide range of organic molecules contained in DOM. As only about 25% of

Introduction The use of chemicals in a school environment cause several issues in not only our health, but our watersheds as well. The chemicals
in use in our school are those that cause damage to our health, they cause this damage with ingredients that are not completely user friendly. A
watershed is a drainage basin, which is a natural depression in the earth's surface, usually containing water, and a divider that separates different
areas. Here in Colorado we have two main watersheds, but we also have several streams considered watersheds. We are in the Cache La Poudre
watershed. A watershed is the transport of different water and it is what is used to drain water into other basins, or oceans or any bigger water
masses. It has stream valleys that bring water to other bodies of water, in which evaporate and return to the top. This is a constant stream in which
is basically recycling water, so we want to keep the water healthy and ready for us to use. In a certain quote, we understand the dangers of what we
do to our watersheds with urbanization,"flooding becomes more prevalent as the area of impervious surfaces increase." (Perlman, 2016). This quote is
saying that the more surface area that was given, such as parking lots, the more runoff comes from our flooding periods. This could be a danger in our
school environment, because we use several chemicals as cleaners. I found greener cleaning supplies from not only our current distributor, but one of

Above n=17 they are solids at room temperature. Although alkanes with higher values of n are found in diesel fuel, fuel oil, petroleum jelly, motor
oils. The fossil fuel resource from which we obtain the alkanes is much valuable to burn it all as a motor fuel. Alkanes derivatives are used in hundreds
of products such as plastics, paints, drugs, cosmetics, detergent, etc. (R, N. n.d.).
Alkenes are an unsaturated chemical compound containing at least one carbon–to–carbon double bond. The simple alkenes have only one double
bond and no other functional groups. For example, (C=C). The boiling points of each alkene are very similar to that of the alkane with the same
number of carbon atoms. In this case, the alkenes have a boiling point which is a small number of degrees lower than the alkane. Each alkene has 2
fewer electrons than the alkane with the same number of carbons. (Clark, J. 2003).
Hydrocarbons that contain carbon–carbon triple bonds. The triple bond adds two elements of unsaturation. For example, (Cп‚єC). They are insoluble in
water. In addition, their boiling points show the usual increase with increasing carbon number. The unsaturated nature of alkynes means that most of
their reactions will be similar to those of alkenes.
The difference between these groups is in the bond types between carbons. Alkanes form only single bonds, alkenes form double bonds, and in
alkynes, there is one triple bond. The structural formulas for each of
