摘要
通过对台州温岭某电子垃圾拆解区土壤的重金属含量调查与分析,利用单项污染指数和综合污染指数对土壤Cr,Cu,Cd,Pb等4种重金属污染情况进行了评价。结果表明,以土壤环境质量国家二级为评价标准,土壤样品中Cd,Cu为主要污染元素,而Cr含量均未超标。其中50%以上的土样已超过中度污染水平,20%左右的土样达到重度污染水平。若以当地自然背景值为评价标准,则80%以上土样超过中度污染水平,且有40%左右土样达到重度污染水平。
An assessment was carried on the heavy metal concentrations in the farmland soil around e-waste disassembling areas, and the different evaluation methods and standards were employed to evaluate the soil quality. The results showed that Cd and Cu were the main pollutants in the farmland soil by the assessment of single factor pollu- tion indexes based on the level of National Standard （GB15612-1995）. Comprehensive pollution index indicated that over 50% of the soil was above the level of moderate pollution, while about 20% soils were heavily polluted. However, based on the level natural background, the soil was mainly polluted by Cd and Pb by the assessment of single factor pollution indexes. Comprehensive pollution index indicated that over 80% of the soils were above the level of moderate pollution, and about 40% soils were heavily polluted.
