摘要:
于2017年1月采集镇江市典型产业园区7个不同点位的青菜及青菜田土壤样品进行重金属含量分析,结果表明,园区青菜中Cr、Cu、Zn元素均值小于食品卫生标准限值,Ni、Cd和Pb元素的均值介于食品卫生标准限值的临界;青菜中Ni、Cd、Pb 3种重金属处于轻度污染状态,Cr、Cu和Zn 3种重金属为无污染状态;青菜田土壤中重金属含量仅Cr和Cd在个别点超过《土壤环境质量农用地土壤污染风险管控标准》(GB 15618—2018)标准限值,其余各点位6种重金属元素均低于标准限值。

Abstract:
The heavy metals content in greengrocery and soil samples from greengrocery plots, which are located in typical industrial parks of Zhenjiang in Jan 2017, have been analyzed. The results showed that the average values of Cr, Cu and Zn in greengrocery were less than the food hygiene standard limits, and the average values of Ni, Cd and Pb in greengrocery were between the critical values of the food hygiene standard limits; the three heavy metals in Greengrocery in industrial parks were in a mild pollution state, and the contents of Cr, Cu and Zn in greengrocery were lower than the food hygiene standard limits. The three heavy metals are non polluted. Compared with the "Standard for Risk Control of Soil Pollution in Agricultural Land of Soil Environmental Quality"(GB 15618—2018), only Cr and Cd exceeded the standard requirements at some individual points, while the other six heavy metals at all points were below the standard.
