摘要
通过对晋城市部分煤矿区蔬菜基地土样重金属含量进行调查、取样、分析,探究晋城市煤矿区附近蔬菜生产基地土壤重金属的含量和污染状况,为发展绿色蔬菜生产提供依据。对比了耕作层与亚耕层重金属含量的变化,并根据中国绿色食品发展中心发布的《绿色食品产地环境现状评价技术导则》中所规定的指标进行了评价。结果表明,该生产基地的土壤重金属未超标,符合绿色蔬菜生产基地的要求。
This paper analyzed heavy metal content in vegetable base soil of part coal mine areas in J incheng, comparison with the non-plough layer and top layer＇s heavy metal content changes, and according to the ＂Evaluation on Environmental Quality of the Production Base for Green Food＂which was issued by the Chinese green food development center, the authors had investigated and appraised the soil index. The results showed that the heavy metal did not exceed the standard required, and it is eligible for growing green food.
