Abstract

In order to increase the safety of tobacco products,and to control or decrease cadmium content in tobacco leaves,the accumulation and distribution of cadmium in flue-cured tobacco were studied by using pot experiment and lab analysis.The results showed that,Cd content was lower both in root and stem of flue-cured tobacco,but it was high in leaves,more than 80% of Cd was found in leaves.Because Cd has high migrantion and flue-cured tobacco is insensitive to Cd,the flue-cured tobacco should be planted in soils with low Cd to prevent Cd accumulation in tobacco leaves and hurt smokers.
