【摘要】 为明确重金属铅在烟叶中的分布情况,测定了不同类型烟草各部位烟叶不同区位中的铅含量。结果表明:①烟叶区位间铅含量分布规律基本表现为:叶尖部、叶边缘较高,叶基部、叶中部次之,主脉最低;②烟叶部位间铅含量表现为:下部叶>中部叶>上部叶;③相同区位的不同部位烟叶中铅的分布规律基本表现为:下部叶最高,中部叶和上部叶较低。

【Abstract】 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.
