To investigate the distribution of heavy metal lead in tobacco leaves, the lead contents in different parts of leaves from different stalk positions of different tobacco types were determined. The results showed that: 1)The lead content was the highest in the tip and edge of leaf, higher in the base and central part of leaf, and low in midrib; 2)The leaves from different stalk positions in the order of lead content were lower leaves > middle leaves > upper leaves; 3)The lead content in the same part of leaves from different stalk positions was higher in lower leaves, than in middle leaves and upper leaves.
