重金属形态与生物毒性及生物有效性关系的研究进展

Researck Progress in Heavy Metal Speciation and Toxicity and Bioavailability of Heavy Metals

简要介绍了近年来环境化学中与生物毒性有关的重金属化学形态分析研究，同时归纳了环境因素对形态分布及生物毒性影响的研究进展。如何建立起形态和毒性两者间的联系，即由物理化学测试给出生物毒性和生物有效性信息，是形态分析的发展方向；在形态与生物毒性关系的基础上建立起新的水质标准，是目前研究的重点。

Knowledge of the relationship between metal speciation and biologcal effects is essential to understand heavy metal impacts on the environment.In this paper progress in this research field and different approaches to meet this requirement in resent years were reviewed.The effects of environmental factors with relation to speciation and toxicity/bioavailability of heavy metals were also discussed.The current efforts are directed towards the development o f chemical speciation schemes which can be related directly to measures of toxicity/bioavailability.Water quality criteria could be improved based on those information.
