中药材种植环境中重金属形态及其影响因素研究

部分中药中存在的重金属污染问题一直是国内外比较关注的.严格控制中药材中有害重金属污染必须从源头抓起.该文综述了影响重金属形态的因素及研究进展,阐述中药材种植环境中重金属的不同形态的活性及影响种植环境中重金属形态的因素.对药材种植基地特别是道地药材的种植基地,因地适宜的改变其种植环境中不同重金属的形态降低其活性,在确保中药中有效成分的同时,控制药材中重金属的含量,使其符合相关质量标准,保障人民群众用药安全,促进中药现代化的发展.

Factors that Affect the Form of Heavy Metals in Traditional Chinese Medicines Planting Environment

The problem of heavy metal contaminant in traditional Chinese medicines has been concerned for a long time in the world. To con- trol this kind of e~ntaminant in traditional Chinese medicines, we must deal with its source. The influencing factors of heavy metal forms, the activity of its different forms in planting environment, and its research progress were reviewed. The plantation of traditional Chinese medicines, especially famous-region drug should consider the influence of heavy metal forms, in order to minimize the contaminant of heavy metal and guarantee the safety and efficiency of traditional Chinese medicines.
