Abstract
The concentration and ecological magnification of selected organochlorine pesticides in aquatic organisms of the Lake Decatur watershed in central Illinois were determined in this study. A review of the use of persistent organochlorine pesticides in the United States and the study area is provided. Samples of Pisces, Decapoda, Insecta, Gastropoda, Annelida, Zooplankton and some amphibians and reptiles were tested for the presence of aldrin, dieldrin, DDT, DDE, heptachlor, heptachlor epoxide, and hexachlorobenzene. Concentration and ecological magnification data are presented for individual samples and samples grouped by taxa. The mean ecological magnification of individual pesticides did not vary substantially between taxa.
