摘要
水体重金属污染已成为全球性的环境问题 ,本文主要介绍了水体重金属污染对水生植物、水生动物的致毒作用和人体健康的危害 ,同时 ,就水体重金属污染的防治对策作了探讨。水体重金属污染的防治途径主要包括两方面 ,即 :源头控制和工程治理。工程治理的方法主要有物理处理法、化学处理法和生物处理法 。
A review with 37 references is given on heavy metal pollution in water bodies including the toxicity of heavy metal pollution in water bodies to aquatic plants and animals and the effects on person health.The control countermeasures against heavy metal pollution in water bodies were also discussed,which could be divided two aspects:controlling pollutant sources and engineering management.Engineering management usually include physical,chemical and biologic treatments.The biologic treatment has better appliance prospect for controlling heavy metal pollution in water bodies.
