摘要:
以2012年广西龙江河镉污染事故为背景，建立了一维重金属模型，结合实测资料对模型进行验证；设定多个突发镉污染事故情景，运用重金属模型模拟镉在水体中的运移过程；提出健康危害评价方法，定量评价事故给柳州市带来的人群健康危害。结果表明：在龙江河镉污染事故真实背景下对柳州市造成的健康危害较小；镉排放强度的提高，会增加下游柳州市居民急性中毒的几率；镉排放总量和事故发生频次的增加，则会加大当地居民的慢性致癌风险；事故发生时应控制在事故地点以下80 km范围内禁止取用水。
Based on the Cd pollution accident in LongjiangRiverin 2012, one-dimensional heavy metal model is built, and its parameters are calibrated by the monitored data. According to the designed data of Cd pollution accident scenarios, the movement process of Cd in the river is simulated by the model. The assessment method of health hazard is built to assess the health hazards caused by the pollution accident. The results show that the health hazard under the real accident background on the people of Liuzhou city is little; the rise of Cd discharge intensity will increase the acute toxicity probability of the people in Liuzhou city; the rise of Cd discharge quantity and frequency will increase the chronic carcinogenesis risk of the people in Liuzhou city; and that water intake and water use actions from the80 kmlong reach downward the accident place should be forbidden during the accident.
