烟草重金属分布规律及防控途径研究进展

Research Progress on the Distribution,Prevention and Control Method of Tobacco Heavy Metals

简述了几种毒理性较大的重金属元素如镉、汞、铅、铬和类金属元素砷对烟株的毒害作用,回顾了近年来烟草科研工作者对这几种重金属在烟株不同部位分布规律的相关研究进展,总结了生产上行之有效的减轻重金属污染、降低重金属毒害作用的调控途径和方法。笔者认为,烟草科研工作者应该积极开展烟叶重金属吸收、分布规律和减害技术研究,同时,烟叶生产相关部门应该对整个生产过程进行严格控制,切断重金属污染源,保证烟叶制品的安全性,从而保护吸食者的安全。

The toxic effect of harmful heavy metals in tobacco, such as Hg, Cd, Cr, Pb and As was sketched in this paper. The research progress in distribution of these heavy metals on different parts of tobacco in recent years was reviewed. The effective prevention and control methods of reducing the pollution and hazards of heavy metals during production were also summarized. It was suggested that the tobacco scientific researchers should study the absorption, distribution and prevention fatherly. Meanwhile, the whole manufacturing process should highly controlled by departments of tobacco productions. The pollution source of heavy metals should be cut off, in order to guarantee the safety of tobacco products, thus protect the safety of smokers.
