Final Report to Congress (EPA 1998), looked specifically at emissions from utility companies and cited Hg as a major contaminant,Įspecially in emissions from coal-fired power plants. The second report, the Study of Hazardous Air Pollutant Emissions from Electric Utility Steam Generating Units. The first of these reports, the Mercury Study Report to Congress (EPA 1997a,b,c), assessed the source and amount of Hg emissions in the United States, the detrimental effects of Hg on humans and wildlife, and the feasibility of control technologies. Environmental Protection Agency (EPA) issued two reports on Hg and its effects on public health to the U.S. The fetus is more sensitive to those effects than the adult (EPA 1997a). In humans, MeHg is known to be neurotoxic. Humans and wildlife are exposed to MeHg primarily through the consumption of contaminated fish, 1 particularly large predatory fish species such as tuna, swordfish, shark, and whale. Hg that enters our oceans, lakes, and rivers is converted to methylmercury (MeHg) by aquatic biota and bioaccumulates in aquatic food webs including fish and shellfish. M ERCURY (Hg) is a persistent substance that comes from natural and anthropogenic sources.
