چکیده انگلیسی
Wild growing mushrooms are traditional food items for man and also an important source of nutrients for small and big wildlife. Nevertheless, they can be species - specifically vulnerable for contamination with heavy metals and radionuclides. We studied a less known phenomenon of accumulation of highly toxic, the alpha-radiation emitter such as 210Po and the beta emitter 210Pb by three Leccinum mushrooms: orange oak bolete L. aurantiacum (Bull.) Gray (previous name Leccinum aurantiacum var. quercinum Pilát), foxy bolete L. vulpinum Watling and slate bolete L. duriusculum (Schulzer ex Kalchbr.) Singer. Fungal and soil materials were collected from areas of a different geochemical composition in the northern regions of Poland. In parallel evaluated was the risk to human consumer due to possible intake of 210Po and 210Pb with a mushroom meal. Results showed a heterogeneous distribution of 210Po and 210Pb activity concentrations within caps and stipes of fruiting bodies. Overall activity concentration for whole dried fungi material ranged from 0.59â¯Â±â¯0.38 to 3.2â¯Â±â¯0.2 Bq 210Po kgâ1 and from 0.45â¯Â±â¯0.04 to 3.1â¯Â±â¯0.2 Bq 210Pbâ¯kgâ1. Evaluation showed that Leccinum mushrooms consumed by locals in typical quantity of 0.5â¯kg (dry biomass) can contribute into annual effective radiation dose at 0.90-3.81â¯Î¼Sv from 210Po decay and 0.31-2.14â¯Î¼Sv from 210Pbâ¯decay, which is a small portion of the annual effective radiation dose of 210Po and 210Pb for human inhabiting the northern regions of Poland.
