摘 要: 介绍了藻类生物富集微量元素的特点和研究现状,探讨了藻类生物富集的作用机理。藻类对有益微量元素的富集作用大于毒性元素;藻类生物富集微量元素的作用机理主要为生物吸附和主动运输,并以主动运输途径富集的微量元素具有较高的生物活性。 The characteristics and research status of bioenrichment of trace elements by algae are introduced, and mechanisms of algae's bioenrichment are discussed in detail. The bioenrichment of healthful trace elements is more efficient than that of toxic ones. The main kinetics for bioenrichment of trace elements by algae is biosorption and active transportation, but only the trace elements bioenriched through active transportation are more active ones in biology.
