【摘要】 选取电子废弃物拆解业比较发达的台州市路桥区下谷岙村为研究区域,对拆解场外土壤的污染状况进行了野外调查和实验分析研究.结果表明:(1)下谷岙村土壤中Cu、Pb的含量均有不同程度的超标;Zn、As、Cr、Mn、Ni的含量均处于国家标准范围内,但除了As、Cr以外,其余元素的含量均高于浙江省土壤背景值,说明土壤中重金属的含量呈明显增加趋势.(2)根据衰减模型,下谷岙村土壤中重金属元素的含量与距离呈现负相关.更多还原

【Abstract】 The present situation of heavy metals pollution of the soil in Xiagu′ao of Luqiao,in Taizhou was investigated and evaluated.The results showed that:(1) In Xiagu′ao,the content of heavy metals Cu and Pb exceeded to varying degrees,the content of Zn,As,Cr,Mn and Ni were in the national standard scope,except As,other elements′ content was higher than Taizhou soil background value,that’s to say,for many years the content has presented obvious increasing tendency.(2) According to the attenuation model,there was showed to be negative correlation between the content of elements in soil and the distance from the factory.更多还原
