中文摘要：
为研究电子废弃物拆解对土壤环境造成的污染,分析了浙江台州电子废弃物拆解区土壤样品中Hg和As的空间传输规律.结果表明,61.4%的样品Hg含量超过国家土壤环境质量一级标准值（0.15mg/kg）,9%的样品Hg含量超过国家二级标准值（0.3mg/kg）,单项污染指数评价显示轻度或中度污染.样品中As的含量均在一级标准范围内.土壤Hg含量受废旧物酸洗源和拆卸源影响较大,而As含量受冶炼源影响较大,其次是酸洗源.除个别样品在下风向上随着距离的增加呈显著下降趋势外,Hg和As含量在不同风向上含量无差异,其余呈现无规律波动,反映了区内存在多个污染排放源.Hg和As含量相关性较差,说明该地区Hg和As的传输和沉降可能受到多种不同因素的影响.
英文摘要：
The contamination of Hg and As in the field contaminated by electronic waste treatment, located in Taizhou, Zhejiang Province was studied, in order to reveal the the soil contamination caused by E-waste break-dividing. The soil were slightly contaminated with Hg. Approximately 61.4% of investigated soil samples were found with Hg content exceeded the first class of national soil environmental quality standard value （0.15 mg/kg）, while 9% were found higher than the second class of 0.3 mg/kg. Of all soil samples, As contents were all below the first class of Chinese standard, suggesting the soil was not contaminated by As. The impact of sources on soil Hg and As content seemed to be quite different. Hg content was more affected by acid washing and E-waste treatment than smelting process, while As content was seemed to be more affected by smelting process and acid washing. As to spatial distribution, the trends of soil Hg and As content changed with distance from the potential sources was not very clearly in most directions. No significant correlation was found between Hg and As content in the soil, which indicated that input of Hg and As content to soil were likely influenced by varied factors at the same time.
