- W2941837503 abstract "为了解福建闽西矿区周边农田土壤中重金属Cd、Pb、Cr积累特征及健康风险,分别测定了农田土壤中Cd、Pb和Cr含量。通过污染指数法和潜在生态危害指数法评价了研究区农田土壤的污染状况和生态危害程度,并应用概率评估模型评价了3种重金属对人体造成的健康风险。结果表明:研究区农田土壤受到不同程度的Cd、Pb、Cr污染,土壤中各元素的单因子污染指数均值大小顺序为Cd > Pb > Cr,综合污染指数为1.21,整体处于轻度污染等级。土壤中重金属的潜在生态风险指数均值大小顺序为Cd > Pb > Cr,综合潜在生态风险指数为226,整体处于中度生态危害等级。研究区土壤中Cd的致癌风险商尚未超过有关专家所建议的风险阈值10-4,对人体造成致癌风险的可能性较低;Pb的非致癌风险商基本都低于其风险阈值1,不产生健康风险;Cr的致癌风险商有12.9%超过风险阈值(10-4),存在对人体健康构成威胁的可能。" @default.
