| 摘 要： | 对漯河市蔬菜种植区土壤进行了重金属Cd、Pb、Hg、As、Cr、Cu、Zn、Ni含量的调查分析,并采用单项质量指数和环境要素综合质量指数相结合的方法对重金属环境质量状况进行了分析与评价。结果表明,漯河市3个主要露地蔬菜生产基地临颍、郾城和舞阳土壤重金属Cd、Hg、As、Pb、Cr、Cu、Zn和Ni的平均含量均低于"食用农产品产地环境质量评价标准"规定的限值。结合重金属的单项质量指数对三地菜地土壤的环境质量进行评价,舞阳有2个样品中的Cu和2个样品中的Ni质量指数大于0.7,环境质量等级为2级,属于尚清洁,处于警戒限;结合重金属的综合质量指数对三地菜地土壤的环境质量评定结果均为1级,土壤环境质量总体上属于清洁,适宜发展无公害蔬菜。

| Abstract: | The vegetable planting areas in Luohe city were investigated about heavy metals Cd,Pb,Hg,As,Cr,Cu, Zn,Ni content. Through the single quality index and environmental elements integrated quality index,the analysis and evaluation of heavy metal environmental quality situation has been done. The results show that：the average con-tent of heavy metals Cd,Hg,As,Pb,Cr,Cu,Zn and Ni in Luohe’s 3 major open fields vegetable production base in Linying,Yancheng and Wuyang were lower than that of“environmental quality evaluation standards”provisions of the limited value of edible agricultural products. Combined with the single quality index of heavy metals,the evalua-tion of environmental quality was carried,with 2 samples of Cu in Wuyang and 2 samples of Ni were greater than 0. 7,the environmental quality level being 2,belonging to the still clean,at warning. Combined with the quality in-dex and heavy metal environment quality in vegetable soil of the three areas,all were assessed as grade 1,while soil environmental quality on the whole belongs to the cleaning grade,which means suitable for the development of pol-lution-free vegetables. |
