Organochlorine pesticides and PCB congeners in human milk from two population groups in Croatia

This study analysed the levels of 20 PCB congeners and organochlorine pesticides in human milk samples collected from two geographically different areas of Croatia. Organochlorine pesticide levels in human milk samples were between the determination limit and 1287 ng/g milk fat on both locations. beta-HCH, gamma-HCH and DDE were detected in all samples. The profile of concentration medians were the same in milk from both locations: DDE>beta-HCH>gamma-HCH~DDT>HCB>DDD>alpha-HCH. The concentration range of PCBs was between the determination limit and 213 ng/g of milk fat. PCB-138 and PCB-153 were found in all analysed samples, while PCB-157 was below determination limit in all samples. Ten PCB congeners were detected in more than 50 % of samples. The concentration median was the same for both locations: the highest concentration was measured for PCB-153, PCB-138 and PCB-180, and the lowest for PCB-60.
