Abstract: To study the comprehensive level of heavy metal in tobacco leaves and the feasibility of Cd as its typical marker,the heavy metal content of Cr,Ni,As,Cd,Se,Hg and Pb in 339 samples of tobacco leaves from 113 major producing areas of China was determined by the method of ICP-MS. The comprehensive evaluation index（ T）,single evaluation index（ S） and representative index（ D） were established and the spatial distribution map was combined to evaluate the heavy metal comprehensive level of tobacco leaves. Results show that the heavy metal comprehensive level of tobacco leaves in most areas in China is in a low level,part of the higher areas are mainly concentrated in four provinces of Hunan,Guangxi,Guizhou and Sichuan,while the lower parts are mainly concentrated in Shandong,Henan and Yunnan provinces; Cr,Ni,As,Se,Hg and Pb has a less contribution to the heavy metal comprehensive level of tobacco leaves,and Cd（ value and distribution） can be a typical markers reflecting heavy metal comprehensive level of tobacco leaves in most areas of China.
