摘要
通过对长春市城郊无公害农业土壤环境中As含量水平调查,并进行了相对于无公害农作物产地环境质量标准中有关As的污染性评价,得出长春市城郊农业土壤环境中As的含量水平状况。长春市城郊无公害农业土壤环境中As含量存在不均衡性;浓度范围在4 12μg/g～18 60μg/g之间,平均值为12 17μg/g;污染呈现出从西南至东北的带状趋势;以《农产品安全质量无公害蔬菜产地环境要求》中GB/T18407 1-2001规定的As的质量标准作为评价标准进行评价,长春市城郊农业土壤环境中As的标准污染指数均小于1,属于未受As污染的土壤类型。图3,表2,参6。
By determining the contents of As in outskirts free-pollutant agricultural lands of Changchun and evaluating the pollution status of As according to the standard of free-pollutant crops,this article concluded the contents level of As in these areas. The content of As was not equilibrium; The range of concentration of As was 4.12μg/g-18.60μg/g and the mean value was 12.17μg/g . Distribution of As in these areas showed a zonal trend from southwest to northeast; Taking the standard value of safe quality free-pollutant vegetables producing area in agricultural crops in GB/T 18407.1-2001 as evaluation standard, the calculated standard pollution index was less than 1, belong to the non-polluted types.
