重金属铬、镍在烟草叶片的分布特征
Study on the Distribution Characteristics of Chromium and Nickel in Tobacco Leaf
摘要
Abstract
The paper studies the distribution of chromium and nickel in tobacco leaf and determines the chromium and nickel content in the different types of tobacco leaf area .The results show that:① nickel content is higher than that of chromium content in tobacco leaves , and the distribution uniformity of nick-el is poorer than chromium;②the chromium in leaf area performance for:the leaf tip, leaf base and leaf margin>leaf central>the main vein;③the nickel in leaf area performance for:the main vein>the leaf tip , leaf base and leaf margin>leaf central .Therefore ,in selecting the raw material for cigarette ,the content of chromium and nickle at different positions should be considered in order to improve the safety of cigarette .关键词
