南丹大厂矿区周边农田土壤重金属健康风险评价
Health risk assessment of heavy metals pollution in farmland soil surrounding Dachang ore district in Nandan
摘要
Abstract
Mining caused ecological,environmental and heavy metal pollution to surrounding agriculture soil. In order to reveal heavy metal pollution and ecological risk from mining on the surrounding farmland,heavy met-al concentrations of Cd,As,Cu,Pb,Zn and Ni were investigated in 6 villages from Dachang in Guangxi.The results show that heavy metal pollutions are quite different with the sampling point changes:far distance,small pollution.Cd and As are the most serious pollutants in these elements,and the ecological risks are highest in Village 1 and Village 3,and higher ecological risk in Village 2.It indicates that heavy metals are more harmful for children than adults by ingestion way,and the crowd harmfulness of As is higher than Cd in carcinogenic metals.So mining soil pollution in the farmland around mining regions has caused health risk.关键词
