河北省地表水重金属环境健康风险评价

The Environmental Health Risk Assessment of Heavy Metals in Rivers of Hebei Province

对河北省地表水重金属污染的状况进行了简述,选取河北省地表水体中有重金属污染现象的5个断面,进行了近5 a的环境健康风险评价。结果表明:重金属污染状况虽然有所好转,但仍然存在环境健康风险,5种重金属的风险值排序大致为六价铬>砷>镉>铅>汞。在剖析重金属污染原因及危害的基础上,提出了减少重金属污染的对策和建议。

The heavy metal pollution of surface water in Hebei Province is briefly introduced , the environmental health risk assessment of 5 water quality monitoring sections which have metal pollution in recent five years are analyzed.The results showed that although heavy metal pollution is taking a turn for the better , environmental health risk still exists, the risk order of five metals is Cr6＋〉As〉Cd〉Pb〉Hg.Based on analyzing the causes and harms of the pollution, the countermeasures to alleviate heavy metal pollution are proposed.
