Organochlorine pesticide residues in chicken fat: a survey.

One hundred and five chicken fat samples were collected between April, 1980 and February, 1982 from seven geographical locations in Kenya (15 samples/area). The samples were subjected to standard extraction and clean up procedures to recover organochlorine pesticides and were subsequently analysed using gas-liquid-chromatography. alpha-, beta-, and gamma-hexachlorocyclohexane/benzene hexachloride (HCH/BHC; Lindane), aldrin, dieldrin, heptachlor epoxide, [1,1-dichloro-2, 2-bis(p-chlorophenyl) ethylene] (p,p'-DDE), [2-(o-chlorophenyl)-2-(p-chlorophenyl)-1, 1-dichloroethane] (o,p'-DDD/TDE), p,p'-DDD, [2-(o-chlorophenyl)-2-(p-chlorophenyl)-1,1, 1-trichloroethane] (o,p'-DDT), and p,p'-DDT were detected in the samples in varying concentrations. A few samples had lindane, dieldrin, and total DDT residue levels above the respective practical residue limit (PRL) values, but for all pesticides, the mean residue values were below the PRL.
