Transcript of Public Health
When coal is burned, mercury is released into the environment (CDC, 2012).
Most common exposure: eating fish or shellfish contaminated with mercury (EPA,2012).
Exposure can: affect nervous system, harm the brain, heart,kidneys,lungs,and immune system (EPA,2012).
Ban on Mercury Exports will begin January 1, 2013
(EPA,2012). What is Lead? Prevention and intervention “ Any chemical or mixture that may be harmful to the environment and to human health if inhaled, swallowed, or absorbed through the skin.”
-U.S. Environmental Protection Agency Mercury Lead Parabens DDT Fun fact! Dental fillings contain mercury! (Poison.org,
2012) Naturally occurring element found in small amounts in the earth’s crust (EPA,2012).
Found in: air,soil,water,and homes.
Exposure: Burning fossil fuels,mining,and manufacturing.
Used in: paints, ceramics,pipes,plumbing materials,gasoline,batteries,
and cosmetics (EPA,2012).
Can travel long distances, stick to soil particles, can seep into groundwater.
Can affect almost every organ and system in body!
Children are most susceptible. What Are Parabens?! Man-made chemical
Most widely used preservative in cosmetics (FDA,2012).
-Also found in foods and pharmaceuticals.
Used in cosmetics to protect against microbial growth
-Maintain product integrity
Can be found in makeup,moisturizers,hair care products, shaving products, and many others!
Disrupt hormone function (endocrine system) (safecosmetics.org, 2012).
Cause human breast tumor??
Health effects from low level exposure are unknown (CDC, 2012).
Currently FDA states there are NO risks for using products containing Parabens. What is DDT? Before 1972 when it was banned, was a commonly used pesticide (EPA,2011)
Quick success and broad use led to the development of resistance by many insect pest species.
Still is persistent in the environment from residues of historical use, can take 15 years to break down
Atmospheric contamination of Great Lakes
Found in soil and water,get absorbed by plants and fish which we eat.
Known to cause damage to liver ,reproductive and nervous system, liver cancer.
In September 2006, the World Health Organization (WHO) declared its support for the indoor use of DDT in African countries where malaria is a major health problem (EPA,2012). Today classified as a probable human carcinogen. Linda Siam
Derek Holland Etiology of Mercury Coal-burning power plants are the largest human caused source of mercury emissions to the air in the U.S.
Gold mining Etiology of Lead, Parabens, DDT/Pesticides Leaded gasoline main source in the past
Main source of Lead:Metals-processing facilities especially lead smelters Source of Parabens:Packaged food Sources of Pesticides: Foods that have been sprayed with pesticides, direct contact with surfaces (such as plants,soils,or structures) where pesticides have been used. (EPA,2012) (CDC,2012) LEAD : •In 1978, the federal government banned consumer uses of lead-containing paint, but some states banned it even earlier •The Healthy Homes Program (HHP) seeks to create safe and healthy housing for vulnerable occupants by addressing environmental health and safety hazards in low-income homes(penn)
• The Lead Hazard Control Program (LHCP)conducts lead poisoning outreach and education. .
Materials like pipes and fixtures that contain lead can corrode •According to CDC The most important step parents, doctors, and others can take is to prevent lead exposure before it occurs Mercury: EPA works with the U.S. Food and Drug Administration (FDA) and with states and tribes to issue advice to women who may become pregnant, pregnant women, nursing mothers and parents of young children about how often they should eat certain types of commercially-caught fish and shellfish
Treatment for mercury usually consists of medicines called chelators to remove mercury from the blood DDT: After 1972, the use of DDT was no longer permitted in the United States.
The Food and Drug Administration (FDA) analyzes a wide variety of imported food items (coffee, tropical fruits, etc.) as well as domestic products to insure that pesticide residues are below FDA tolerances. Incidence/Prevalence Lead and DDT have both been banned
in the United States since the 1970's
but still show up at toxic levels in
certain circumstances including:
foods (fruits vegetables,grains, meats)
household products (aresol sprays, cleaners), and toys.
Old homes, businesses and factories waste .
(Source epa.gov 2012) Incidence And Prevelance Mercury
Mercury is found in Coal-burning power plants. Therefore homes surrounding these are where poisoning is most likley, I.e. lower income families living\ working in these plants.
DDT QUESTIONS PARABENS : Still research being done
