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 investigate the disposal of subacute arsenic poisoning by drinking contaminated water together with experience and to provide reference for the handling of similar incidents in the future. Methods 342 villagers drinking polluted water were investigated by household, physical examination and urine samples were tested, field epidemiological investigation was carried out, and drinking water was tested. Results The arsenic content of waste water was 2.40 mg / L, the arsenic content of peripheral water was 0.63 mg / L, the arsenic content of water source was 0.01 mg / L. The mercury content in water source, peripheral water and abandoned mine water did not exceed the national drinking water standard (1.089 ± 1.64) mg / L in 342 villagers drinking polluted water, and 45 villagers in non-polluted water drinking water for arsenic contrast test, the average value was (0.134 ± 0.163) mg / L. Conclusion According to the clinical manifestations, epidemiological investigation and laboratory test results, a total of 8 cases of subacute arsenism were diagnosed, and this incident was judged as a case of arsenic poisoning caused by drinking water pollution.
