The aim of the study was to determine the content of selected heavy metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn) present in the fruiting bodies of Agaricus bisporus (Lange) Imbach., depending on the site of picking and on a geographical region of Poland. Mushroom samples were collected in selected regions of Poland: Lower Silesia, Silesia, Pomerania and Kujawy, Wielkopolska, Lubuskie. Samples of Agaricus bisporus were wet mineralized in a 3:1 mixture of concentrated HNO3 (ultra pure) and HClO4 (AR). The content of heavy metals was determined with atomic absorption spectroscopy FASS using an AAS Zeiss apparatus. The content of heavy metals in the fruiting bodies of Agaricus bisporus (Lange) Imbach. wild growing in Poland was varied and amounted to: Cd 0.68-6.14; Cr 0.38-6.93; Cu 1.90-101.71; Fe 33.01-432.24; Mn 2.86-387.43; Ni 0.20-3.09; Pb 0.98-42.83; Zn 31.87-124.84 (in mg kg-1). Excessive levels of Cd, above the permissible content, were detected in the fruiting bodies collected from whole Silesia. Concentrations of CD above the permissible Cd content were observed in the fruiting bodies picked in Silesia region in four out of eleven locations: Katowice (Murcki), Pszczyna (Kobiór), Sośniowice (Biały Dwór), Pawonków (Dziewicza Góra). In the other regions, the permissible content of cadmium and lead in the fruiting bodies of Agaricus bisporus (Lange) Imbach. was not exceeded. The concentrations of micronutrients (Zn, Cu, Mn, Fe) and pollutants (Cd, Cr, Pb, Ni) were strictly dependent on tge sampling sites as well as geographical regions of Poland.
