按卫生部要求，为尽快查清地方性砷中毒在吉林省的流行情况，依据以往水质检测资料，对吉林省西部的通榆县４个乡进行了环境砷含量及流行病学调查研究。共检水样１７４份，其中砷含量超标３７份，占 ２１．２６％，水砷最高值为 ０．２０７ｍｇ／Ｌ。土壤及农作物砷含量均在国家规定的正常范围内。共调查 ４ ９０３人，发现有不同程度的掌跖部角化、皲裂、皮肤色素沉着、脱失患者共９３人，占调查人数的１．９％，其中年龄最小的６岁、最大８０岁，患病率男性高于女性（Ｐ＜０．００５）。共检疑似患者尿样４２份，其中１５人尿砷含量超标（＜０．０９ｍｇ／Ｌ），占３５．７％，尿砷最高值为０．４０１ｍｇ／Ｌ。检发样１３份，有８份砷含量超标，占６１．５４％。根据环境砷及流行病学调查结果，可确认本区内有地方性砷中毒流行，致病因子是饮水中含量超标的砷。
According to the request of the Ministry of Health, in order to find out the epidemic situation of endemic arsenism in Jilin Province as soon as possible, the environmental arsenic content and epidemiological investigation of 4 townships in Tongyu County, western Jilin Province were conducted according to the data of water quality testing in the past. A total of 174 water samples were collected, of which 37 were arsenic exceeded the standard, accounting for 21.26%, the highest water arsenic was 0.207 mg / L. Soil and crop arsenic levels are within the normal range of the state. A total of 4 903 people were surveyed and found to have varying degrees of palmoplantar keratosis, chapped, pigmented skin, the total loss of 93 patients, accounting for 1.9% of the survey population, of which the youngest 6 years old, maximum 80 years old, The prevalence was higher in males than females (P <0.005). A total of 42 urine samples were tested, of which 15 patients had excessive urinary arsenic (<0.09mg / L), accounting for 35.7%, and the highest value of urinary arsenic was 0.401mg / L. Seizure sample 13, 8 arsenic content exceeded, accounting for 61.54%. According to the environmental arsenic and epidemiological survey results, endemic arsenic poisoning prevalence in this area can be confirmed. The causative agent is arsenic whose content in drinking water exceeds the standard.
