Occurrence of individual polychlorinated biphenyl (PCB) congeners in the environment, foodstuffs and other biological materials was assessed. Analysis of specific PCB congeners (28, 52, 101, 138, 153, 180), occurring in animal raw materials and foodstuffs most frequently, has been implemented. Sample processing, isolation of fat from milk, meat, organs, fat tissue and eggs, and separation of PCB from fats using the sorbents Florisil or Ekosorb (a new Czechoslovak sorbent based on modified silica gel, Kavalier Glassworks, Votice) are described in detail. Individual PCB congeners were determined by capillary gas chromatography (gas chromatograph Varian VISTA 6 000, equipped with a Ni-63 ECD
