摘要:The study investigated the extent of contamination of with p,p- DDT, p,p-DDE, hexachlorocyclohexane isomers, lindane ((γ-HCH) and δ-HCH, dieldrin, aldrin, endrin, endrin aldehyde, endrin ketone, alpha-endosulfan, endosulfan sulfate, chlordane, heptachlor and methoxychlor in tissues of grasscutter ( Thryonomys swinderianus ), obtained from the Gomoa East district of Ghana. The organochlorine pesticide residues in the samples were soxhlet extracted using a mixture of hexane and acetone. The extracts were cleaned up using florisil and analysed using a gas chromatograph equipped with an electron detector (GCECD). The results indicated that all the analyzed samples were contaminated with the studied organochlorine pesticides. Aldrin and heptachlor were the principal contaminants in all the samples. The muscle had the highest pollutant load followed by the liver and then the kidney. The levels of organochlorine pesticide residues detected in all the tissues were below the accepted Maximum Residue Limits (MRL), as adopted by the WHO/FAO Codex Alimentarius Commission (2005).
