Mercury

Mercury has long been identified as an environmental hazard and of great concern to public health. Mercury is toxic to vital organs and is deadly when entered into the bloodstream in quantities greater than trace amounts. Recently, mercury has been observed in oceanic fish that are caught in the wild and sold at markets and in fish caught at reservoirs.

"Mercury has been found in largemouth bass (Micropterus salmoides) from five South Carolina reservoirs. According to investigators, "mercury concentrations in largemouth bass (Micropterus salmoides) bass were compared among five reservoirs in South Carolina. Three of these reservoirs (Lake Russell, Lake Thurmond, and Lake Marion) are accessible to the public and two (L-Lake and Par Pond) are located on the U.S. Department of Energy's Savanna River Site (SRS), which is closed to public access." (NewsRx, 2006)

The implication is the U.S. DoE has potentially released excess mercury, which has drained into these lakes and reservoirs. Most industrial sites are major environmental hazards as the release chemicals into the environment. The DoE is similar to private industrial operations such that chemicals are also released into the environment that causes considerable damage to the eco system and creates major health hazards for the population at-large.

However, "no mercury concentrations in excess of the U.S. Food and Drug Administration action level (1.0mg/kg) were found in any bass from the public-accessible reservoirs. However, the majority of fish from these reservoirs had mercury concentrations that fall into or exceed the U.S. Environmental Protection Agency consumption category of 'no more than one per week'.

1.3 billion. Health and medical groups cited widely accepted scientific research describing mercury as a 'potent neurotoxicant' that can cause developmental and learning difficulties, reduce IQ, and impair motor function, vision and hearing." (ANJ, 2005)
Asbestos

Asbestos has been in the news as a public health threat for over a half century. The issue with asbestos is not in the material itself, but in the release of fibers from asbestos into the air and into human lungs. Implications are greatest with regard to asbestos contamination within the school setting and with construction/mining workers.

"Corn is convinced that the question of risk-whether there is more risk in removing asbestos materials or leaving them in place-should have been seen as a scientifically settled issue. The EPA exaggerated risks and avoided uncertainties, while Congress did not take time to understand the science and passed a law that encouraged schools to proceed with high-risk asbestos abatement. Yet if the point is a high degree of confusion and controversy, Corn's apparent disappointment in a confused policy outcome seems inconsistent." (Kovarik, 2007)

"Asbestos is an occupational and environmental hazard of catastrophic proportions. Asbestos has been responsible for over 200,000 deaths in the United States, and it will cause millions more deaths worldwide. The profound tragedy of the asbestos epidemic is that all illnesses and deaths related to asbestos are entirely preventable." (LaDou, Landrigan, Bailar, Foa, 2001)

"The toll of illness and death among asbestos workers in mining, construction, and heavy industry is well-known." (LaDou, Landrigan, Bailar, Foa, 2001)

Lead

Lead is another well-known threat and is of greatest danger to children and to those within industrial environments where lead is known or is commonly used. "Lead poses a serious environmental health risk to young children, causing such irreversible health effects as mental retardation, stunted growth, and hearing and visual impairment. Studies suggest that various sectors of the public, including children's caregivers, are not sufficiently concerned about…
