title: [The level of metal impurities in some edible mushrooms growing wild].
abstract: The amount of lead, cadmium, copper, zinc and mercury has been determined by atomic absorption spectroscopy in 96 samples of edible mushrooms, growing wild fresh edible fungus and dried (Boletus scaber, ceps) mushrooms, acquired from 6 regions in Poland: Zielonogórskie, Toruńskie, Ostrołeckie, Radomskie, Warszawskie and Lubelskie in 1990 and 1991. The level was found to be higher than that allowed by the polish standard PN-89/A-78510 Mushroom Processed Foods. Dried mushrooms and other legal acts eg. Instruction of the Ministry of Health section Social Welfare of 12th November 1990, the content of zinc in dried mushrooms (all samples) and in fresh edible fungus from the Zielonogórski and Toruński region. The content of copper in fresh edible fungus did not usually correspond with the requirements, whereas in the dried mushrooms (Boletus scaber, ceps) it exceeded the level only insignificantly in individual samples (average from studied regions was found to be within limits). The content of lead in dried mushrooms complied with the requirements of the standard, except for samples of ceps from Zielonogórski region, where it insignificantly exceeded the allowed level of 2.0 mg/kg. The average content of zinc and copper in dried mushrooms did not exceed the allowed levels. The levels of mercury determined in the studied samples do not cause any excitement in light of the FAO/WHO agreements. A high level of contamination with cadmium was noted in all studied samples, being 2.5 times higher in edible fungus, 6-8 times higher in Boletus scaber and 19-23 times higher in dried ceps.(ABSTRACT TRUNCATED AT 250 WORDS)
