dc.description.abstractThis thesis reviews the history of the development and use of pesticides, and of residue analytical techniques. References are provided on the distribution, persistence and toxicity of pesticides. The optimal conditions for gas chromatographic analysis of five organochlorines and one carbamate with a Varian Model 3700 Gas Chromatograph were established. The recoveries of five organochlorines in water using the EPA method of extraction and clean-up were determined. Disti1led-and-deionized water was analyzed for pesticide residues. A lake sampling device to be operated from a boat was designed and is described. Description Is also given of sampling techniques designed for lake environments. A pilot sample from the IAR Lake was analyzed for pesticide residues prior to analysis of real lake water samples. Possible sources of error are discussed. The analytical results are compared with documented data on residue levels for both polluted and unpolluted waters, and with permissible levels of residues in potable and surface waters. Suggestions for further work are made; and, finally, a statement is made on pesticide pollution of the 1AR Lake.en_US
