摘要
目的初步评价新疆部队驻地饮用水中重金属污染物砷对人体健康产生的潜在威胁。方法在对13个部队饮用水中砷(As)含量进行检测的基础上,建立水环境污染健康风险评价模型,并对重金属As通过饮水途径所引起的健康风险做出初步评价。结果 l3个部队饮用水中As的平均质量浓度为As(1.566×10-4～4.333×10-3)mg/L;饮用水中As引起的个人年均风险最大达2.915×10-5/a。结论调查的新疆部队饮用水中As对人体的健康危害的个人年均风险,未超过国际辐射防护委员会(ICRP)推荐的最大可接受值5.0×10-5/a。
Objective To evaluate potential threat of As,the heavy metal contamination in drinking water to health of Xinjiang army.Methods On basis of detecting drinking water sample for concentrations of As from 13 armies in Xinjiang,model for evaluating health risk of water pollution was established and the health risk caused by As through drinking water was assessed preliminary.Results The average concentrations of As in water taken by Xinjiang army was from 1.566×10-4 mg/L to 4.333×10-3 mg/L.Annually maximum personal risk associated with As in water was 2.915×10-5/a.Conclusions The annually personal health risks associated with As in water taken by Xinjiang army is lower than the maximum allowance levels recommended by ICRP（5.0×10^-5/a）.
