摘要：In this study, 50 raw milk samples of Anatolian water buffalo (Bubalus bubalis, Linneaus, 1758) belonging to
different dairy farmers in the Kızılırmak Delta in Samsun, Turkey, were investigated for contamination by 9
organochlorine pesticides (OCPs) and 16 polychlorinated biphenyls (PCBs). The contaminants were
extracted cryogenically from the milk fat and their concentrations were determined with a gas
chromatography-electron capture detector (GC-ECD). The mean level of alpha-hexachlorocyclohexane
(HCH) in the milk samples was 6.34 ng/g/fat, beta-HCH was 20.41 ng/g/fat, gamma-HCH was 9.77
ng/g/fat, ∑DDTs was 18.11 ng/g/fat and ∑Indicator-PCBs was 127.27 ng/g/fat. The mean values, except
for aldrin and ∑DDTs, were above the maximum residue limits (MRLs) stated in the European Commission
(EC) Regulations and Turkish Food Codex (TFC). Regular monitoring and reporting of the levels of
persistent organochlorines in the meat, milk and processed products of water buffaloes is essential for the
assessment of human, animal and environmental health.
