The objective of the study was to determine the levels of congeners (28, 52, 101, 118, 153, 180, 138) of polychlorinated biphenyls in edible mushrooms available at the market in the region of Warmia and Masuria. The research material constituted 15 samples of edible mushrooms available at the market in Warmia and Masuria, including: five species of fresh mushrooms originating from this region; five species of dried mushrooms originating from different regions in Poland, and champignons produced by various producers in Poland. It was confirmed that fresh mushrooms had the highest content of polychlorinated biphenyls of 13.11 μg/kg of lipids; this fact urges further research into this issue. It was also found that even large amounts of mushrooms eaten did not cause acute intoxication. The health hazard can be a result of, even, very small amounts of PCB congeners accumulated in human organisms.
