Abstract		HR gas chromatographic PCB patterns in human/poultry fat tissue and hair/plumage in samples from a polluted region of Bela Krajina /Slovenia/ were investigated. The concentration of PCBs in human adipose tissue was found to be 9.62 micro g/g in comparison to 0.67 micro g/g in the adipose of the non-exposed population, and in poultry fat 12.8 micro g/g on a fat basis. The corresponding values in human hair and poultry plumage were 0.90 micro g/g and 0.20 micro g/g of original weight. The difference in PCB patterns between fat and hair can be attributed to the different routes of contamination (ingestion, air transport), to the time of exposure and physicochemical properties (octanol-water partition coefficients, Henry's law constants and the metabolism) of some individual congeners. Hair could be used for the assessment of ingestion of contaminated food and of the PCB levels in the air. In fat tissue PCB congeners with higher metabolic stability are enreached, whereas in hair PCB congeners with higher concentrations in air and with high octanol-water partition coefficients predominate.
