Abstract：Absorption ability of nine flue-cured tobacco varieties to six heavy metals of Cu,Pb,Cd,Cr,As and Hg was studied.The results showed that flue-cured tobacco varieties differed greatly in the absorption ability to the six heavy metals.Heavy metals could be divided into three categories according to the absorp-tion ability of flue-cured tobacco varieties to the six heavy metals.The first class,Cd,was enriched strongly by flue-cured tobacco varieties,the average enrichment factor was 3.751.The second class,Hg,was en-riched as a medium level by flue-cured tobacco varieties,the average enrichment factor was 0.735.The third class,including Cu,Pb,As and Cr,was enriched weakly,the average enrichment factor was 0.066.
