| 摘 要： | 利用美国环保署提出的水质健康风险评价模型,对大连市近5a的生活饮用水环境进行评价,探究水体中所含物质对人体健康的潜在影响。以国际辐射委员会推荐的最大可接受限值为参考进行分析,结果表明,区域内的水中化学致癌物主要是Cr＋6,致癌风险超过了国际辐射委员会推荐的最大可接受值5.0×10-5/a;非致癌物中只有氟化物风险超标;致癌物的风险大于非致癌物的风险。根据评价结果可知在水质治理过程中,应优先治理致癌物Cr＋6。

| Abstract: | The model of health risk assessment proposed by United States Environmental Protection Agency is applied to assess the domestic drinking water environment in Dalian for the past five years. The potential health risk of the pollutant in the water is discussed. The maximum allowed level （5.0 × 10-5a-1 ） that is recommended by ICRP is referred to. The results show that the Cr ＋ 6 is the main chemical carcinogen, and the health risk is above the maximum allowed level recommended by ICRP. In non - carcinogens, only the risk of the fluoride goes beyond the standards. The health risk of carcinogens is significantly higher than that of non - carcinogen. Thus, more attention should be paid to Cr ＋ 6 in the water treatment. |
