摘要: Even some edible mushroom species contain injurious compounds. Potentially procarcinogenic agaritine occurs in the genus Agaricus , gyromitrin, particularly Gyromitra esculenta . Formaldehyde detected shiitake mushrooms seems to be of natural origin and is not a cause for concern. Occurrence nicotine has yet been elucidated. A decomposition product coprine from Coprinus spp. induces alcohol intolerance. Some saprobic can accumulate considerable levels nitrates. Mushrooms residues various xenobiotics. Great attention focused on radioactivity. The radioactivity higher than that other vegetables due high level potassium including radioactive isotope 40 K. ectomycorrhizal have ability radiocesium after contamination following disasters. Information rhabdomyolysis, allergies, adverse dermal respiratory reactions sensitive individuals provided.
