摘要
根据中国土壤污染现状和土壤环境监测的需求,结合国内外研究经验,以江西省土壤污染物为研究对象,在计算各污染物健康风险的基础上,结合哈斯图解法对污染物进行优先级排序,进而得出优先控制污染物。研究结果表明,江西省土壤污染物对儿童的致癌和非致癌风险比成人高,且As的非致癌风险超过1,有非致癌风险;其致癌风险超过可接受水平(10^(-6))。江西省的土壤优先控制污染物为As。
According to the situation of soil pollution and the requirements for soil environmental quality monitoring,screening of priority control pollutants of soils were studied based on the health risk assessment of pollutants.A case study was carried out in Jiangxi Province with the application of the Hasse diagram technique.The health risk assessments of soil pollutants were studied and the priority control pollutants were further screened out from the soil pollutants of Jiangxi Province.The results showed that cancer risk and non-carcinogenic risk of children were higher than those of adults in Jiangxi Province.The non-carcinogenic risk value of As exceeds 1,indicating that there was non-carcinogenic risk for soil of Jiangxi Province.The cancer risk of As was also with a value higher than the acceptable level(10-6).As was the priority control pollutant of soil in Jiangxi Province.
