Abstract：In the present paper,samples were digested by high pressure digestion pots,reducing the loss of trace elements during the digestion process. The contents of trace elements in edible fungi such as Ca，Na，K，Mg，Mn，Ba，Fe，Co，Ge and Cu were determined by inductively coupled plasma atomic emission spectrometry. The relative standard deviation with high pressure digestion pots was 0.16%-2.86%,and that with wet method was 0.33%-3.49%,so it could be seen that the measurement precisions of the two methods were good,and the former was better. The measurement results with the two methods were checked by t-test,and the values in the range of 0.002 4-2.473 were lower than t0.99,9(3.25). The measurement results showed that the two methods had no obvious differences,namely no system errors occurred. The recovery rates with high pressure digestion pots were in the range of 96.6%-103%. The method of high pressure digestion pots was suitable for the determination of trace elements in edible fungi with the adva
