Organochlorine pesticides (OCPs) are persistent organic pollutants. It can provide fundamental data to help researchers comprehensively understand the influence of contaminants inalake aquatic environment, investigate contamination levels and distribution characteristics of OCPs. The results showed that hexachlorocyclohexanes (HCHs), dichlorodiphenyltrichloroethanes (DDTs) and its metabolites were the main OCPs in surface water and sediments, respectively. Accumulation of OCPs in wild fishes was observed.DDTs and HCHs in the lake were mainly historical residues. OCPs’ concentrations in
sediments were stable, while those in surface water varied during the sampling period. Concentrations of contaminants in surface water were higher in wet season than in dry season. The contaminant levels in the inlet area were higher than in the effluent area. Dietary intake of fishes and water was the main exposure sources of DDTs and HCHs, but the contamination level was low, and it did not lead to significant health risks.
