title: Pesticide contaminants in selected species of edible wild mushrooms from the north-eastern part of Poland.
abstract: The aim of this study was to determine the level of chlorinated hydrocarbon residues in selected edible mushrooms from north-eastern Poland. The experiment was carried out on 45 samples consisting of 15 fruiting bodies each of the following species: Boletus edulis, Imleria badia and Cantharellus cibarius. Dried samples were subjected to extraction of lipids with a Soxhlet and a standard procedure-based on the decomposition of lipids by concentrated sulfuric acid and the release of organic insecticides to the hexane layer-was used to determine chlorinated hydrocarbons. The quantitative determination of DDT, DDE, DDD and γ-HCH were conducted using gas chromatography with electron capture detection (GC-ECD). Chlorinated hydrocarbons were found in all tested samples. The contents of these compounds varied between all three species. Mean content of γ-HCH in B. edulis, I. badia and C. cibarius was: 2.60; 4.83; 7.52 µg kg-1of lipids, while the content of ΣDDT was: 57.02; 25.20; 127.10 µg kg-1of lipids, respectively. These results show that mushrooms from the north-eastern part of Poland can be used as potential bio-indicators of environmental contamination with chlorinated hydrocarbons. Moreover, the studied fungi could still be used as food due to the low levels of analyzed organochlorine compounds.
