Abstract：In order to investigate the content of heavy metals and assess heavy metals contamination and health related risks of common edible fungi,the content of total lead(Pb),cadmium(Cd),mercury(Hg),and arsenic(As)in edible fungi were determined,and assessment of heavy metals contamination was made by GB 2762-2022.The detection rate of heavy metals was 100.00％in 42 edible fungi samples,the exceeding standard rate of heavy metals was 26.2％,exceeding samples were all wild edible fungi samples,the content of the same heavy metal in wild edible fungi was higher than artificial planting edible fungi.There were significant differences in the content of the same heavy metal in edible fungi in different species and different areas.The quality of edible fungi samples such as morel,Sweethead fungus and Pleurotus citrinopileatus could be evaluated as grade three,while the quality of Tricholoma matsutake could be evaluated as grade one.The current situation of heavy metals contamination of Pb,Cd in wild edible fungi could not be ignored.The heavy metal contamination degree of wild morel,S.fungus and P.citrinopileatus was high.Close attention should be paid to the risk management since there were definite health hazards to human body.
