摘要
目的:探讨水质健康风险评价模型对水质监测的意义。方法:2017年2月—2019年2月,应用美国EPA水质健康风险评价模型对伊川县饮用水水质监测资料进行全方位的健康风险分析。结果:居民饮用水水质健康风险较为平稳,多数饮水点重金属指标检测结果远低于最高标准。2017年乡镇饮用水中一般化学指标检测结果较2018年无明显差别,2019年饮用水中铝、锌、锰含量高于2017年和2018年,2017年乡镇饮用水中菌落总数检出量巨大。2018年和2019年伊川县城市饮用水重金属污染风险检测点A和检测点B水中的镉含量较2017年明显降低。结论:水质健康风险评价模型对水质监测结果具有重要参考价值。
OBJECTIVE To explore the value of water quality health risk assessment model for water quality monitoring.METHODS The quality monitoring data of local drinking water,from February 2017 to February 2019, was analysed and compared comprehensively based on the US EPA water quality health risk assessment model. RESULTS The health risk of drinking water quality was relatively stable, and the far detection results of heavy metal indexes in most drinking water points were far below the highest standard. The detection results showed that there was no significant difference between the detection results of general chemical indexes in drinking water in 2017 and 2018. The contents of aluminum, zinc and manganese in drinking water in 2019 were higher than those in 2017 and 2018. Rural drinking water sources were complex, mostly household well water. The results showed that in2017, the total number of bacteria detected in drinking water in villages and towns was huge. According to the United States EPA water health risk assessment model to detect cadmium content in a factory in Yichuan County, research showed that in 2017, the risk of heavy metal pollution in urban drinking water in Yichuan point A and point B had no difference. 2018 and 2019 test results showed that the risk of heavy metal pollution in the area significantly reduced. CONCLUSION The water quality health risk assessment model showed critical reference value for water quality monitoring.
