| 摘 要： | 在辽宁省铁法矿区采集了33个土壤样品,对样品中重金属含量进行了测定。根据测试结果,分析了铁法矿区土壤中重金属含量分布特征。采用化学致癌物和躯体毒物质健康危害风险模型进行健康风险评价,并引用重金属评价等级体系分别对成人和儿童健康风险水平进行具体分析,得出以下结论：铁法矿区土壤中各种重金属元素均属于强变异,表明人类活动对该矿区土壤重金属含量产生了较大影响。矿区土壤中Cd含量超过国家一级标准值,但是并未造成较高的年均风险值。开采时间越长的矿区,年均风险值越大。致癌重金属的年均风险值较大,三种致癌重金属风险大小依次为Cr6＋〉As〉Cd;成人年均风险值处于Ⅰ、Ⅱ两个等级,在同一矿区儿童年均风险值要比成人年均风险值普遍高出两个等级,表明土壤中重金属元素对成人身体影响不大,对儿童影响较严重。

| Abstract: | 33 soil samples are collected in Tiefa coal-mining and heavy metals content are determined.According to the test result,the distribution of soil heavy metals in Tiefa coal-mining is analyzed.Using health risk assessment model of chemical carcinogens and body toxic substances the heavy metals' health risk is estimated,and citing heavy metal rating system,the risk levels for adults and children's health are analyzed respectively. Some conclusions are drawn as follows: Heavy metal elements in soil of Tiefa min... |
