中文摘要:
      通过对镇江地区土壤样品中Cd监测结果统计分析表明,全市69个样品中Cd质量比范围为0.06 mg/kg~1.37 mg/kg,均值为0.23 mg/kg,与全国背景值相比,有一定程度富集;样品中Cd质量比成偏态分布,相对标准偏差较大。选用单项污染指数法对Cd污染程度评价表明,镇江地区83%的土壤样品未受到Cd污染,14%为轻度污染,3%为中度污染。结合镇江地区的产业结构分析,电镀行业是土壤Cd污染的主要来源,道路运输、农药化肥在一定程度上也加重了污染。
英文摘要:
      Based on the statistical results of Cd in soil samples in Zhenjiang area,it showed that the quality ratio of Cd,in the city's 69 samples was in the range of 0.06 mg/kg to 1.37 mg/kg,mean 0.23 mg/kg.Compared with the background value,a certain degree of enrichment has appeared.And the quality ratio of Cd in samples was skewed distribution,and the ralative standard deviation was big.The single pollution index of Cd pollution degree evaluation showed that there was 83% of soil not polluted by Cd,14% for mild pollution,and 3% for moderately pollution in Zhenjiang area.Combined with the analysis of the industrial structure in Zhenjiang area,electroplating industry was a major source of Cd pollution in soil,road transport,pesticide and fertilizer to a certain extent,also increased the degree of contamination.
