[Arsenic, cadmium, lead and mercury in bay bolete Xerocomus badius and tolerance limits]

Abstract

In the article are reviewed available data on arsenic, cadmium, lead and mercury contents of the fruiting bodies of Bay Bolete in Europe. Cadmium and lead contents of Bay Bolete at the sites unpolluted with those elements reaches up to 5 and 20 mg/kg dry matters, respectively (up to 0.50 and 2.0 mg/kg fresh weight), i.e. is a much more greater when compared to the tolerance limit of 1,0 and 2,0 mg/kg dry weight in force earlier in Poland. In the light of available analytical data a suggested tolerance limit for cadmium in Bay Bolete should be 5 mg per kg of dried fruiting bodies, and 20 mg per kg of dried fruiting bodies for lead.
