Abstract: Fish and sediment samples were used as a case study to determine the levels of organochlorine pesticide residues in the Ashaiman Reservoir, Ghana. The fish species collected from the Reservoir included
Sarotherodon melanotheron,
Tilapia guineensis,
Tilapia zilli and
Clarias gariepinus. The samples were extracted using solid phase extraction and analyzed using a Gas Chromatography (GC) equipped with Electron Capture Detector (ECD). A total of 15 organochlorines (OCs) namely; β-HCH, δ-HCH, lindane, heptachlor, aldrin, dieldrin, endrin, α-endosulphan, β-endosulphan, endosulphan sulphate, methoxychlor, γ-chlordane, p,p′-DDE, p,p′-DDD and p,p′-DDT were analyzed. In both fish and sediment samples, all the organochlorine pesticides investigated exhibited non-detectable levels at a detection limit of 0.005 mg/kg. The levels of pesticide residues analyzed in the fish samples were below maximum residue limits specified by the European Union and Australia and thus not of appreciable health concern to consumers.
