【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。
[Abstract]:Objective to investigate and deal with subacute arsenism caused by drinking polluted water and summarize the experience so as to provide reference for the treatment of similar incidents in the future. Methods 342 villagers drinking polluted water were investigated, and their urine samples were examined by physical examination, and epidemiological investigation was carried out on the spot, and drinking water was tested. Results the arsenic content in waste mine hole water was 2.40 mg / L, the arsenic content in peripheral water was 0.63 mg / L, the arsenic content in source water was 0.01 mg / L, the mercury content in source water, tip water and waste mine hole water was within the limit of national drinking water standard. The average value was 1.089 卤1.64 mg / L, and 45 villagers' urine samples without drinking polluted water were tested for arsenic. The average value was 0.134 卤0.163 mg / L.
