摘要
目的了解山西省晋中市饮水型地方性砷中毒病区降砷改水工程的运转情况和水砷含量现状。方法2023年5-8月,按照《山西省砷暴露地区居民生活饮用水砷含量调查方案》的要求,选取山西省晋中市饮水型地方性砷中毒历史病区平遥县、介休市、祁县的29个高砷村作为监测村,调查改水工程运转情况;并采集监测村居民生活饮用水水样,采用氢化物原子荧光光度法测定水砷含量。同时,以29个高砷村所在乡镇为单位,开展相邻局域范围内改水工程运转情况及居民生活饮用水砷含量监测。结果2023年,共监测山西省晋中市3个县(市)的29个高砷村,均已全部改水且改水工程均正常运转;水砷含量范围为0.000~0.047 mg/L,其中27个村水砷含量<0.01 mg/L。共监测晋中市高砷村所在乡镇相邻局域范围内81个自然村,均已全部改水且改水工程均正常运转;水砷含量范围为0.000~0.043 mg/L,平遥县、介休市、祁县分别有4、7、2个自然村水砷含量为0.01~0.05 mg/L。结论山西省晋中市全部高砷村已完成改水,改水工程均正常运转。大部分高砷村水砷含量符合国家饮用水标准(<0.01 mg/L)。
Objective To learn about the operation of arsenic reduction and water improvement projects and the present situation of arsenic level in drinking water in drinking water type endemic arsenic poisoning areas in Jinzhong City,Shanxi Province.Methods From May to August 2023,in accordance with the requirements of the"Investigation Plan for Arsenic Content in Drinking Water of Residents in Arsenic Exposed Areas of Shanxi Province",29 high arsenic villages in the drinking water type endemic arsenic poisoning historical areas of Pingyao County,Jiexiu City and Qi County in Jinzhong City,Shanxi Province were selected as monitoring villages to investigate the operation of water improvement projects.The drinking water samples of village residents were collected and water arsenic level was measured by hydride atomic fluorescence spectrophotometry.At the same time,monitoring of the operation of water improvement projects and water arsenic level for residents within adjacent local areas were carried out in townships where 29 high arsenic villages located.Results In 2023,a total of 29 high arsenic villages in 3 counties(cities)of Jinzhong City,Shanxi Province were monitored,all of which had undergone water improvement and all water improvement projects were operating normally.The range of water arsenic level was 0.000-0.047 mg/L,with 27 high arsenic villages had water arsenic level<0.01 mg/L.A total of 81 natural villages within the adjacent local areas of high arsenic villages in Jinzhong City were monitored,all of which had undergone water improvement and the water improvement projects were operating normally.The range of water arsenic level was 0.000-0.043 mg/L,and there were 4,7,and 2 natural villages in Pingyao County,Jiexiu City and Qi County with water arsenic level ranging from 0.01 to 0.05 mg/L.Conclusions All high arsenic villages in Jinzhong City,Shanxi Province have completed water improvement,and the water improvement projects are operating normally.The water arsenic level in most high arsenic villages meets the national drinking water standard(<0.01 mg/L).
