Abstract The sample was digested by the quartzose digestion pot at high-pressure under relatively low temperature, reducing the loss of Se during the digestion process. Study on the method of using ICP-MS to determine Se in the edible fungi shows that it exhibits positive correlation between the concentration of sample and integration time, and the response value. When the concentration of Se in the sample is higher than 50 μg·L-1,the integration time can be 0.1 s; or it can be 2.0 s when the concentration of Se is lower than 5 μg·L-1. The standard curve was accomplished for 1.0-500 μg·L-1 when determining the content of Se in the edible fungi. The recoveries are in the range of 99.96% -102.7%. This method has advantages of simplicity, speediness, delicacy, high stability, high accuracy, etc. It is suitable for the determination of trace Se in the edible fungi.
