Atmospheric deposition of toxic pollutants to the Great Lakes as measured by the integrated atmospheric deposition network

Article Abstract:

A study of air pollution data over the Great Lakes region as collected by the Integrated Atmospheric Deposition Network showed atmospheric loading of pollutants to the Great Lakes consisted of seven organochlorine pesticides, four polychlorinated biphenyl species, four polycyclic aromatic hydrocarbons and four trace metals. Loading rates of the different compounds were not determined since atmospheric loading was equal to air-water equilibrium.

Temporal trends in gas-phase concentrations of chlorinated pesticides measured at the shores of the Great Lakes

Article Abstract:

Regulatory controls on pesticides proved effective in reducing the concentration or organochlorine pesticides in the environment as evidenced by the temporal trends in gas-phase concentrations of chlorinated pesticides at the shores of the Great Lakes. The atmospheric half-lives of the hexachlorocyclohexanes was found to range from 2.2 yr for gamma-HCH at Lake Michigan to 7.3 yr for gamma-HCH at Lake Ontario.

Temporal trends of semivolatile organic contaminants in Great Lakes precipitation

Article Abstract:

Researchers from Canada and the U.S. sampled precipitation samples around the Great Lakes Integrated Atmospheric Deposition Network to determine the concentrations of organochlorine from 1991 to 1997.
