摘要
测定了湖北不同类型烟草(烤烟、白肋烟和马里兰烟)各部位烟叶及烟叶微区(叶基部、叶中部、叶尖部、叶边缘和主脉)的砷含量。结果表明:烟草下部叶砷含量最高,上部叶砷含量最低;烟叶叶尖部、叶基部、叶边缘砷含量较高,叶中部次之,主脉最低;下部叶各微区中的砷含量较高,上部叶各微区中砷含量较低。
Arsenic contents in different parts（upper, middle and lower leaves） and micro-regions（leaf base, leaf middle, leaf tip, leaf margin and leaf primary vein） of tobacco leaf of the flue-cured tobacco, burley tobacco and Maryland tobacco from Hubei province were determined. The results showed that the arsenic content in lower leaves were the highest, while in upper leaves the lowest; in micro-regions, leaf tip, leaf base and leaf margin showed higher arsenic content, followed by leaf middle, and leaf primary vein showed the lowest arsenic content; arsenic content in microregions of the lower leaves was high, while in micro-regions of the upper leaves was low.
