DETERMINATION AND COMPARISON OF THE ORGANOCHLORINE PESTICIDE RESIDUE LEVELS AMONG BENNI FISH OF SHADEGAN, MAHSHAHR AND SUSANGERD CITIES, KHOZESTAN PROVINCE IN IRAN

Concentrations of hexachlorocyclohexane isomers (β,γ,δ hch), dichlorodiphenyl trichloro ethane (pp, opddt) and its metabolites ( ppdde, ppddd), aldrin, dieldrin, heptachlor , heptachlor epoxide, endosulfan isomers (α, β) and metoxychlor were determined in benni fish collected from shadegan, mahshahr and susangerd cities at khozestan province in iran. all the collected fish were contaminated by 14 investigated organochlorine pesticides. the highest and lowest mean concentrations of organochlorine pesticides belonged to β- hch (65.36 μg/kg) and op ddt (0.13 μg/kg) and were found in mahshahr and shadegan benni fish respectively.
