摘　　要：目的通过一起饮用污染水引起亚急性砷中毒事件的调查处置,总结经验,为今后类似事件处置提供参考。方法对饮用污染水的村民有342人进行入户调查、体检并对其尿样进行检测,开展现场流行病学调查,对饮用水进行检测。结果废弃矿洞水砷含量为2.40 mg/L,末梢水砷含量0.63 mg/L,水源水砷含量0.01 mg/L,水源水、末梢水、废弃矿洞水检测汞含量未超过国家饮用水标准限值;对342名饮用污染水村民尿砷检测,均值为(1.089±1.64)mg/L,临村45名没有饮用污染水村民尿样进行砷对比检测,均值为(0.134±0.163)mg/L。结论结合病人临床表现、流行病学调查和实验室检验结果,共诊断亚急性砷中毒病例8例,判断本次事件为一起饮用水污染引起的砷中毒事件。Objective To learn experiences of conducting survey on a subacute arsenic poisoning, and provide references for future similar disposal. Methods We conducted household survey, physical examination and urine test on 342 villagers who had drunk contaminated water. We conducted field epidemiological investigation and test the drinking water. Results The arsenic content of abandoned mine water was 2.40mg/L, and their contents were 0.63mg/L and 0.01 mg/L in peripheral water and source water, respectively. The mercury levels in source water, peripheral water and abandoned mine water did not exceed national standard limit for drinking water. The mean of urinary arsenic from 342 villagers, who had drank contaminated water, was 1.089 ＋ 1.64mg/L. 45 villagers, who did not drink contaminated water in the near village, were tested for urine arsenic and the mean of urine arsenic was 0.134 ＋ 0.163mg/L. Conclusion We combined clinical manifestations, epidemiological investigation and laboratory of patients, and 8 arsenic poisoning cases were diagnosed. Therefore, this is a arsenic poisoning caused by contaminated drinking water.
