Objective To investigate the pollution status of lead （Pb）， cadmium （Cd）， arsenic （As）， mercury （Hg） and chromium （Cr） in Ganoderma lucidum sold in Lishui City and to evaluate the exposure risk of toxic and harmful elements among consumers in Lishui City.Methods The contents of lead， cadmium， arsenic， mercury and chromium in 50 samples of Ganoderma lucidum sold in Lishui were detected and the contamination degree was evaluated by single factor index and comprehensive pollution index. The consumption of Ganoderma lucidum in Lishui city was investigated， and the dietary exposure level was calculated by point assessment method to assess the health risk. At the same time， the leaching rate of toxic and harmful elements was tested according to two common eating methods.Results The average single-factor pollution index of Pb， CD， As and Hg in Lishui Ganoderma lucidum was less than 0.6， which was safe level. Conservative estimation based on direct consumption method，the average daily consumption of ganoderma lucidum consumption group was 3.04 g， and that of high consumption group （P₉₅） was 10.00 g. The dietary exposure levels of five toxic and harmful elements were all at a safe level by point assessment method， and the risk level was Cr>Cd>Pb>Hg>As. Lead， cadmium， arsenic and chromium were all leached in the soaking solution and mercury was not. The leaching rate of poisonous and harmful elements in Ganoderma lucidum tablets was higher than that of Ganoderma lucidum.Conclusion The dietary exposure risk of toxic and harmful elements caused by the consumption of Ganoderma lucidum is low and in an acceptable range.
