Abstract： In order to establish a new method that can rapidly and accurately detect different harmful elements in food，with edible fungi and spices as the research objects，inductively coupled plasma-mass spectrometry （ICP-MS）-close interpolation method and standard curve method are used respectively to compare and determine the content of seven elements such as Pb ，Cd， Cr ， Hg ，As，Mn and Cu in samples. The results show that the detection limit of ICP-MS-close interpolation method is between 0. 021 8ng/mL and 0.279ng/mL ， and the quantification limit is between 0.0728ng/mL and 0.930ng/mL ， The average spiked recovery rates of the samples are 83.7%～99.7% ，and the relative standard deviations are between 0.2% and 1.8% .Compared with standard curve method in the national standard （national standard method），there is no significant difference between the two methods （ P>0.05; .Conclusion：ICP-MS-close interpolation method has a good linear relationship and reduces detection time，and does not need to draw standard solution working curve and measure blank solution，so it has a good promotion and application prospect.
