目的 进一步查清吉林省地方性砷中毒病区分布情况。方法 通过回顾性调查及重点调查相结合的方法 ,在吉林省西部的通榆县、洮南市重点砷中毒疑似病区开展了工作。结果 通过对 2个县的 5个乡 (镇 ) 3 2个行政村的13 7个自然村的调查 ,在 3 2个行政村中 ,有 2 4个行政村有饮水砷含量超标的井存在 ,占 75 % ;在所调查的 13 7个自然村中 ,有 2 7个自然村可定为地方性砷中毒病区 ,占 19.71%。另有 47个自然村可定为高砷区 ,占 3 4.3 1% ,高砷区总人口为3 0 70 9人。 2县总的砷暴露人口为 3 779人。结论 根据环境地理及病情调查结果 ,可确认吉林省地方性砷中毒病区 ,主要分布在吉林省西部平原 ,致病因子是饮水中砷含量超标。
Objective To find out the distribution of endemic arsenism in Jilin Province. Methods Through the combination of retrospective investigation and key investigation, we carried out the work in the suspected ward of arsenic poisoning in Tongyu County and Taonan City in the western part of Jilin Province. Results Through the investigation of 137 natural villages in 32 administrative villages in 5 townships (towns) in 2 counties, of the 32 administrative villages, there are 24 wells in the administrative villages with drinking water exceeding the standard, accounting for 75%. Of the 13 villages surveyed, 27 villages are endemic arsenic poisoning, accounting for 19.71%. Another 47 villages are designated as high arsenic area, accounting for 4.311% of the total, while the population of high arsenic area is 3 709 people. The total arsenic exposure in 2 counties was 3,779. Conclusion According to the results of environmental geography and disease survey, endemic arsenism in Jilin Province can be confirmed, which is mainly distributed in the western plains of Jilin Province. The pathogenicity factor is that the arsenic content in drinking water is excessive.
