Abstract		Chlorinated aromatic compounds (PCBs, PCNs, CBzs) and their partition in environmental samples from the polluted area of the Bela krajina region were determined. The PCB level in human adipose tissue in non-occupationally exposed residents was 9.6. microg/g in comparison to 0.7 microg/g in similar samples from a 'non-exposed' population, and in poultry fat 12.8 microg/g compared to 0.05 microg/g from a non-polluted region. The corresponding PCB values in human hair and poultry plumage from the polluted region were 0.9 microg/g and 0.2 microg/g. The PCB levels in aquatic moss, river sediment and fish as lonog term indicators of water pollution of the river Krupa reached 4.0, 40 and 980 microg/g and in pine needles as a long term indicator of air pollution, 2.2 microg/g. In soil samples from the same area the level was 1.6 microg/g (all dry weight basis). The PCB profile was characteristic of the individual indicator. PCB patterns in individual samples were explained by the different source and routes of contamination (through food ingestion, water, air) and the exposure time. The PCN levels were below 1 percent of the PCB levels, but CBz levels were not related to PCB levels in individual samples.
