Abstract

Mercury (Hg) occurs both naturally and from anthropogenic sources throughout the environment. The primary natural source of Hg is degassing of the earth's crust involving mainly elemental mercury vapor. In Wisconsin this contributes 66% of the total mercury (Sheffy 1987). Mercury is also used for numerous industrial applications some of which insult the environment with their by- products. Several of these anthropogenic sources include: pulp and paper, the chlorine industry, fossil fuels, mining, painting, sewage treatment, and agriculture (Brosset 1983; Airey 1982; Lindvquist 1981); these are accountable for approximately 34% of Wisconsin's total Hg (Sheffy 1987). Once within the environment, mercury is transported by the atmosphere and deposited in the form of both wet and dry precipitation into lakes and streams (Glass 1986).
