Gas chromatographic analysis of water and bottom mud sediment samples collected monthly during a one-year period from sites on the Maumee, Portage, Sandusky, Huron, and Grand River systems indicated only very infrequent and sporatic occurrence of minute concentrations of pesticide residues. Samples were analyzed for organochlorine and organophosphate insecticides and for triazine and chlorophenoxy acid herbicides. Concentrations of residues in the few positive analyses were generally less than 10 parts per billion for detected insecticides and less than 50 ppb for triazine herbicide. Diazinon, dieldrin, and the DDT family of compounds were the most common insecticides detected. Atrazine was the most often detected herbicide. (Modified author abstract)
