摘要

摘要: 以江西省某铜矿弃渣场拦渣坝下游农田土壤为研究对象,对3个地块(1 ^#、2 ^#和3 ^#)土壤中重金属Cu、Pb、Cd、As和Sb污染现状进行分析和评价。结果表明:3个地块土壤中各重金属平均浓度均高于江西省土壤背景值,其中1 ^#地块Cu、Cd和3 ^#地块Cu、Sb、As的平均浓度均超过GB 15618—2018《土壤环境质量农用地土壤污染风险管控标准(试行)》水田风险筛选值(pH<6.5);1 ^#、2 ^#、3 ^#地块的尼梅罗综合指数(P_综)分别为11.30、1.25、2.95,分属重度、轻度和中度污染水平;地累积指数法评价结果表明,1 ^#和3 ^#地块土壤均受到不同程度的Cu、Cd、Sb、Pb、As污染,2 ^#地块土壤受到不同程度的Cu、Pb、Sb、As污染;健康风险分析表明,3个地块土壤对成人和儿童均无非致癌风险,对儿童的致癌风险均超过美国国家环境保护局规定的最大可接受限值(1.0×10 ^-4),其中1 ^#和3 ^#地块土壤对成人的致癌风险也超过最大可接受限值,存在不可接受的致癌风险,3种致癌重金属的致癌风险(CR)表现为As>Cd>Pb,且3种暴露途径对致癌风险的贡献为口腔>皮肤>呼吸。

Abstract: In order to explore the pollution status and evaluate the pollution risk of heavy metals (Cu, Pb, Cd, As and Sb) influenced by copper deposits, the concentration of heavy metals of three farmland soil plots (block 1 ^#,2 ^# and 3 ^#) downstream of a copper mineslag dump in Jiangxi Province were analyzed. The results showed that the average contents of the five heavy metals in the three plots were higher than the background values in Jiangxi Province (normal soil), and the average contents of Cu, Cd in block 1 ^# and Cu, Sb, As in block 3 ^# exceeded the paddy field standard limit (with pH<6.5) of Soil Environmental Quality-Risk Control Standards for Soil Contamination of Agricultural Land (Trial) (GB 15618-2018). The analysis of Nemero Composite Index showed that the P of blocks 1 ^#, 2 ^# and 3 ^# was 11.30, 1.25 and 2.95 respectively, which were at the level of heavy, light and medium pollution, respectively. The Muller's Accumulated Index analysis showed that block 1 ^# and 3 ^# were differently polluted by Cu, Cd, Sb, Pb, As, and block 2 ^# was polluted by Cu, Pb, Sb, As at different levels. The health risk analysis showed that there was no non-carcinogenic risk for adults and children in the three farmlands, and the carcinogenic risk (CR) for children exceeded the maximum acceptable limit (1.0×10 ^-4) stipulated by US EPA. The CR of blocks 1 ^# and 3 ^# for adults also exceeded the maximum acceptable limit, with unacceptable carcinogenic risk. The CR of the three carcinogenic heavy metals was in the order of As>Cd>Pb, and the contribution of three exposure routes to carcinogenic risk was oral>skin>breathing.
