Sažetak
Fruiting bodies of Boletus mushrooms were collected in the season of 2021 in three different areas of Croatia (Central, Northern and Mountainous Croatia). Sampling locations were determined by the highest and lowest (Control area) content of lead (Pb) and cadmium (Cd) in the soil from the Republic of Croatia, categorized according to the Geochemical Atlas of the Republic of Croatia. Inductively coupled plasma mass spectrometry (ICPMS) technique was used to determine the metal content, while the activity concentration of 137Cs in Boletus mushrooms was determined by the gamma spectrometric method. The highest Cd content among three areas was found in mushrooms from Northern Croatia where 15% of samples exceeded the maximum level of 5 mg/kg dry mass (dm) set for contaminants in wild fungi. The content of Pb in mushrooms from all three Croatian areas ranged 0.02-3.94 mg/kg dm, which corresponds to levels reported in the literature to reflect unpolluted areas. 137Cs activity concentration in all analysed samples was below the legal threshold for edible products, 600 Bq/kg. Considering that many species of wild edible mushrooms can be harmful to human health because they can accumulate studied metals and radionuclides in excessive amounts, it is of outmost importance to regularly monitor their concentrations.
