目的评价北方某地农村饮水水质所带来的人群健康风险。方法利用2015年某地区农村饮水水质监测数据,通过健康风险评价模型,计算基因毒物质和躯体毒物的个人年风险。结果基因毒物质评价结果显示,饮水中砷和铬的风险比较大。躯体毒评价结果显示,该区各乡镇饮用水躯体毒物质的风险度均较低。毒物总风险评价结果显示,砷的毒性风险度在总风险中成了关键。结论该地区部分乡镇农村饮水砷的健康风险较大。
Objective To evaluate the population health risks brought by drinking water quality in rural areas in northern China. Methods Based on the monitoring data of rural drinking water quality in a certain area in 2015, the personal risk of genotoxic and somatic poisons was calculated through the health risk assessment model. Results The results of genotoxicity evaluation showed that the risk of drinking arsenic and chromium was relatively high. Somatic poison evaluation results show that the risk of drinking water body toxins in each township is low. Toxicological risk assessment results show that the toxicological risk of arsenic in the total risk has become the key. Conclusion The health risks of arsenic in rural drinking water in some townships in this area are higher.
