| 为探究甘肃白银靖远电厂周边土壤重金属污染的健康风险特征，采集周边建设用地和耕地土壤样品，分析8种元素（As、Cd、Cr、Cu、Hg、Ni、Pb和Zn）的含量特征，并将Monte Carlo模拟引入USEPA人体健康风险模型评估其概率健康风险，利用PMF模型与概率健康风险评估相耦合的方法确定土壤优先污染控制源和控制元素。结果表明，除耕地土壤中的As以外，靖远电厂周边土壤中各元素的含量均值均高于甘肃省土壤背景值；靖远电厂周边土壤重金属对成人和儿童存在可忽略的非致癌风险和可接受的致癌风险，儿童较成人更易受到土壤重金属的影响；As、燃煤源与燃煤〖CD*2〗农业混合源分别为人体健康风险的优先控制元素、优先控制源。 |
| 英文摘要: |
| This paper analyzed the content characteristics of eight elements（As， Cd， Cr， Cu， Hg， Ni， Pb， and Zn） in soil samples from the construction land and cultivated land around Jingyuan Power Plant in Baiyin， Gansu， assessed the probabilistic health risks by introducing Monte Carlo simulation into the USEPA human health risk model， and identified the priority pollution control sources and elements by coupling PMF model with probabilistic health risk assessment， in order to explore the health risk characteristics of heavy metal pollution in the soil. The results indicated that except for As in the cultivated soil， the average content of each element in the soil around Jingyuan Power Plant was higher than the background value of the soil in Gansu Province. The heavy metals in the soil around Jingyuan Power Plant posed negligible non carcinogenic risks and acceptable carcinogenic risks to both adults and children， with children being more susceptible to the effects of heavy metals in soil than adults. As， along with the sources from coal combustion and coal combustion agriculture were regarded as the priority control element and control sources for human health risks. |
