Organochlorine residues in freshwater fishes in Nigeria

Abstract
Several organochlorine pesticide residues in fish from various freshwater ecosystems in Bendel State of Nigeria were investigated. The fish species analysed were selected among those commonly used for human consumption. Among the compounds identified and quantified were the DDT group, HCB and lindane (γ‐BHC). The results indicate an appreciable accumulation in fish of P,P´‐DDT, P,P´‐DDE and γ‐BHC. The other pesticide residues detected had considerably lower levels.
