辽宁大伙房水库水质健康风险评估

摘要

The health risks of water quality were evaluated,results showed that:water quality in the health hazards caused by various pollutants,the total risk for the individual were 1.0 × 10-6/year.Water quality in the health hazards caused by genotoxic risk of the individual in descending order for the hexavalent were chromium ＞ arsenic ＞ ; physical health hazards caused by toxic substances in the risk of individuals descending order of lead ＞ mercury ＞ Cyanide ＞ ammonia ＞ phenol.Therefore,attention should be paid in the management of toxic substances on chemical carcinogens gene emissions control.%对大伙房水库水质健康风险进行了评估,结果表明水库水质中各类污染物所致健康危害的个人年总风险为1.0×10-6/a.水质中基因毒物质所致健康危害的个人年风险由大到小排列为六价铬＞砷＞；躯体毒物质所致健康危害的个人年风险由大到小的排列为铅＞汞＞氰化物＞氨氮＞挥发酚.因此在管理上应重视对基因毒物质中化学致癌物排放量的控制.
