Résumé

Specimens of three species of birds were collected from Lake Nakuru, Kenya, between September and October 1990. Samples of liver, kidney, muscle, fat and brain tissue were removed and analyzed for organochlorine pesticide residues. Fat was extracted and the content of three lindane (BHC/HCH) isomers (?, ? and ?), aldrin, heptachlor, heptachlorepoxide, endrin, dieldrin, DDD, DDE and DDT was determined. The samples contained varying residue levels of 12 organochlorine pesticides. No residues of 0, p'-DDD were detected. The most prevalent compounds were DDE and ?-BHC, found in 95.5 per cent and 66.4 per cent of the samples, respectively. The highest median residue concentration was 207 mg kg?1×10?3 of DDE in pelican fat tissue. White pelicanPelecanus onocrotalus, and the white-necked cormorant,Phalacrocorax carbo, showed greater concentrations of organochlorine residues than the lesser flamingo,Phoenicopterus minor. The mean DDE concentrations in pelican liver samples in 1970 and 1990 were 64 mg kg?1×10?3 and 274 mg kg?1×10?3, respectively. In cormorant liver samples the mean DDE concentration was 15 mg kg?1×10?3 in 1970 and 52 mg kg?1×10?3 in 1990. The mean DDE concentration in flamingo liver remained more or less similar at 2 mg kg?1×10?3 in 1970 and 1990.
