In 1994 samples of bovine milk were taken at 98 sampling points (2 in each of the 49 districts of Poland). Levels of organochlorine and polychlorinated biphenyls (PCB) were determined using capillary gas chromatography. In almost all milk samples DDT and PCB residues were detected. Mean concentration of DDT in milk fat was 0.065 mg/kg (range between 0.011 and 0.382 mg/kg) and of PCB was 0.017 mg/kg (range between 0 and 0.051 mg/kg). Other organochlorine pesticides (mainly HCH isomers and hexachlorobenzene (HCB)) were found at low concentrations and only in some samples. HCB and gamma -HCB were found in approximately 60% and alpha -HCH in approximately 30% of all samples tested.
