According to the document, 16 businesses were formally complained against for supplying jewelry containing high levels of lead and cadmium in violation of California's Metal-Containing Jewelry Law. Testing found over 340 jewelry items exceeding legal limits for these toxic metals by up to 1,000 times. Majority of the jewelry tested was inexpensive items from stores nationwide. The law restricts lead and cadmium levels in jewelry and outlines penalties for noncompliance, with the goal of protecting public health from toxic metal exposure.
This document summarizes the toxicity of beryllium and cadmium. Beryllium is highly toxic when inhaled and can cause progressive pulmonary fibrosis and lung cancer. It is classified as a known human carcinogen. Cadmium is also toxic when inhaled or ingested, and can cause acute respiratory issues like cadmium fume fever in welders as well as chronic pulmonary fibrosis and kidney damage from long term exposure. Both beryllium and cadmium are classified as human carcinogens.
This presentation discusses several harmful elements from the periodic table, including their uses, effects on humans, and effects on the environment. It provides detailed information about beryllium, mercury, cobalt, lead, radon, nickel, and uranium - describing their common uses, how they impact human health, and how they can damage the environment. The document aims to educate readers about the dangers these elements can pose.
Glass is an amorphous solid that is often transparent and has many practical uses like window panes and tableware. It is neither a true liquid nor crystal solid on a microscopic scale, existing in an intermediate "amorphous" state. Glass is produced through melting raw materials like silica sand, soda ash, and limestone at high temperatures, then rapidly cooling the mixture to prevent crystallization. The continuous glass melting process is best for high volume products like containers while the batch process allows for more customization. Glass has a wide variety of applications from housing and electronics to medical and renewable energy.
Cadmium is a soft, bluish-white metal that is toxic and carcinogenic. It occurs naturally in zinc ores and is produced as a byproduct of zinc smelting. Cadmium is used in batteries, pigments, plastics, and other applications. Long-term exposure can cause kidney and lung damage and cancer in humans. The main sources of human exposure are burning fossil fuels, waste incineration, and contaminated food and water from industrial pollution.
Cadmium is a soft metal that is a byproduct of zinc production. It can cause health issues when inhaled or ingested, as the body absorbs it and stores it in organs like the liver and kidneys. Dental amalgam fillings contain cadmium, which can stain teeth and impact periodontal health over time. Cadmium poisoning was responsible for the Itai-itai disease that affected women working in battery factories in Japan, causing bone and kidney problems. Mild cases are treated with supplements, while more severe cases require hospitalization, supplements, and potentially chelation therapy or dialysis.
Lead is a highly toxic metal that can cause lead poisoning when ingested or inhaled. Young children are most at risk because lead exposure can impair brain development. Common sources of lead include old lead-based paint, contaminated dust, some toys, and water pipes. Symptoms of lead poisoning range from abdominal pain to behavioral issues. Treatment involves removing the lead source and possibly chelation therapy to remove lead from the body. Preventing lead exposure is important, especially for children.

Alan Turing was born on June 23, 1912 in London, England. He became interested in math and science at a young age and enrolled at Cambridge University. In 1936, he published a seminal paper on computable numbers that introduced the concept of a Turing machine, laying the foundations for computer science. Turing machines are abstract devices that can be in a finite number of states and use a tape divided into squares to manipulate symbols according to a table of instructions. This allows them to compute any computable sequence or number. Turing provided examples of simple machines that compute repetitive sequences like 010101 to illustrate how they work.

Copper cyanide is a white to cream colored powder that is insoluble in water and reacts violently with magnesium. It is poisonous and can cause a number of health effects through ingestion, inhalation, eye and skin contact. First aid measures include flushing eyes and skin with water and seeking immediate medical attention for ingestion or inhalation. It is used in electroplating, mining and other industries but has also caused several accidents through mine collapses releasing cyanide or illegal cyanide trails poisoning the environment. Material safety data sheets are important for logisticians handling hazardous chemicals to safely transport, store and handle them while avoiding exposure.

The document discusses various methods for assaying gold, including fire assaying, ICP spectrometry, X-ray fluorescence, touchstone testing, and density measurement. Fire assaying is the most widely used and accurate method, involving melting a sample with lead and silver, separating out the noble metals in a cupel, and dissolving away silver to determine the gold content. The method works well for alloys with 30-99.9% gold but requires modifications if nickel, palladium, or platinum are present. Other techniques provide alternatives but with reduced accuracy compared to fire assaying.

It then discusses where lead is commonly found in the environment, such as in soil, water, paint, gasoline, and certain consumer products. The document outlines the various ways people can be exposed to lead and the health effects of lead poisoning, which can impact the brain, kidneys, and blood. It provides details on signs and symptoms of lead exposure and concludes by discussing the medical effects of lead on children and adults.
Mercury toxicity can occur from exposure to mercury in various forms. Elemental mercury is a liquid metal that vaporizes at room temperature into an odorless gas. Inorganic mercury combines with other elements to form salts, while organic mercury combines with carbon. Dental amalgam used in fillings contains mercury. Exposure risks include inhalation of vapors during placement or removal of fillings. Mercury is a potent neurotoxin that can cross the blood-brain barrier and cause neurological and developmental effects. Symptoms of toxicity depend on the level and route of exposure, ranging from rashes to kidney damage.
Mercury toxicity is discussed, including the various forms of mercury, how it enters the environment, and health effects. Mercury is a heavy metal that exists in elemental, inorganic, and organic forms. Elemental mercury is a liquid that vaporizes easily and is toxic. Dental amalgam used in fillings contains mercury, and small amounts can vaporize during placement or removal. Exposure to mercury can cause neurological, kidney, respiratory, and developmental effects. Guidelines are provided for safe handling and disposal of dental mercury.

Testing for Cadmium
and Lead
According to the California
Department of Toxic Substances
Control (DTSC) and the Center for
Environmental Health (CEH), a
formal complaint was filed against
16 businesses that have allegedly
been supplying retailers, and
consumers, jewelry containing
high levels of lead and cadmium.
This resulted in the violation of
California’s Metal-Containing
Jewelry Law, where the analysis,
conducted by the DTSC
Environmental Chemistry Lab
found over 340 jewelry items
exceeding the legal limit of
metals cadmium and lead by as
much as 1,000 times the legal
limits in California.
Majority of these tests were
conducted on inexpensive jewelry
obtain from costume, retail,
discount, and dollar stores
nationwide. Some toxic jewelry,
that’s been tested, had labels
claiming to be “lead free.”
Many consumers are unaware of
these harmful metals due to
venders and distributors using
misleading statements, false
advertisement claims, and
engaging in fraudulent business
practices in violation of the state’s
Proposition 65 Law.

4. TOXIC METALS IN JEWELRY TESTING FOR CADMIUM AND LEAD | 4
ELEMENTS IN THEIR PURE STATE
Cadmium
Cadmium is a soft bluish-white metal that
resembles zinc in various ways. The metal
and its compounds are toxic and should be
handled with care. Cadmium is used in
fusible alloys that melt at low temperature.
Lead
Lead is a soft, malleable and heavy post-
transition metal. Metallic lead has a bluish-
white color after being freshly cut, but it
soon tarnishes to a dull grayish color when
exposed to air. Lead has a shiny chrome-
silver luster when it is melted into a liquid. It
is also the heaviest non-radioactive element.
The ATSDR 2013
Substance Priority List

Cadmium ranks number 7out of 275
hazardous substances in the environment.

Lead ranks number 2 out of 275 hazardous
substances in the environment.

Cadmium
Cadmium is an inorganic bluish-
white element that naturally occurs
within the earth’s crust. It is usually
foundas a mineral combinedwith
other elements suchas oxygen,
chlorine, orsulfur. Most cadmium
used in the United States is
extracted duringthe productionof
other metals like zinc,lead, and
copperwhere concentrationsand
toxicity tend to be higher. Cadmium
does notcorrodeeasily andhas
many uses, includingbatteries,
pigments, metal coatings,and
plastics.
How Is It Used InJewelry?
In children’s jewelry, cadmium is
used to make the coating of
jewelry shiny and to add weight
and mass to each piece.
Lead
Lead is a naturally occurringbluish-
gray metal foundin small amountsin
the earth's crust.Lead canbe found
in all parts ofour environment.Much
ofit comesfrom humanactivities
includingburningfossil fuels,
mining, and manufacturing.Lead
has many different uses.It is used in
the productionofbatteries,
ammunition, metal products(solder
and pipes),and devices to shield X-
rays. Becauseof health concerns,
lead fromgasoline, paints and
ceramic products,caulking,andpipe
solder has been dramatically
reducedin recent years.
How Is It Used InJewelry
Lead has oftenbeen used in jewelry,
to make the article heavier, brighten
colors,and to stabilize orsoften
plastic.
What is Cadmium and Lead?
5. Toxic Chemicals Found in
Jewelry Can Cause Health
Problems
Cadmium and Lead appears onthe
Proposition 65 list of chemicals
known to cause cancerand
reproductiveharm.
Exposure
Inhalationofcrushedparticles
Ingestionfrom placing cadmium
tainted productsinmouth.
Neither Cadmium norlead can
absorb throughtheskin
Cadmium
Cadmium is a heavy metal of
considerable toxicity as it
concentratesin the kidney, liver and
various otherorgans andis
considered more toxic than either
lead ormercury.
Ten to fifty percentof inhaled
cadmium dustis absorbed,
depending onparticle size.
Absorptionthroughskin contactis
negligible. Aboutfive to ten percent
ofingested Cdis absorbed,also
depending onparticle size.

Lead
Lead is a toxic
metal, which
doesn't break down
in the environment
and accumulatesin
ourbody. High
levels oflead have
been foundin
jewelry, especially
inexpensive
children’s jewelry.
Impacts
Behavioral Problems
Learning Disabilities
Jointand muscle weakness
Anemia
OrganFailure
Headaches
Irritation of the Digestive
Tract
Hyperactivity
Death
Childrenare More Susceptible to
these HealthEffects!
Children are more susceptible to
adverse health effectsbecause their
bodies are growingquickly and their
brains are still developing.
Lead containingjewelry poses a
particular concernbecausechildren
often place jewelryin their mouths,
whichcanresult in lead absorption at
dangerouslevels or very serious
health effectsif the jewelry is
accidentally swallowed.
FUN FACTS
5%-10%
Cadmium is absorbed from ingestion of
particles depending on its size.
143,000
Lead exposure is estimated to account
for 143,000 deaths per year with the
highest burden in developing regions.
600,000
Childhood lead exposure is estimated
to contribute to about 600,000 new
cases of children developing
intellectual disabilities every year.
0.005ppm
The EPA has determined that lifetime
exposure to 0.005 ppm cadmium is not
expected to cause any adverseeffects.
