Limnological Factors Affecting Pesticide Residues in Surface Waters
Samples of water, mud, periphyton and fish were taken from the Iowa River above and below the Coralville Flood Control Reservoir near Iowa City, Iowa, Lake MacBride and the Cedar River. All samples were analyzed for the major chlorinated hydrocarbons. These include DDT and its metabolites, BHC and its isomers, heptachlor and its metabolites, aldrin and its metabolite dieldrin. Concentrations of pesticides in fish were far higher than those observed in the periphyton. A variety of factors were found to influence pesticide residue levels. Pesticide determinations for waters, muds, and periphyton and fish are summarized. (Author)
