城郊部分菜地土壤重金属污染简述

介绍了中国城郊部分菜地土壤重金属污染现状,系统地分析了部分菜地土壤重金属污染元素、污染趋势、污染城市分布、污染来源及污染原因,同时,着重探讨了重金属在土壤中的分布、向上迁移、向下迁移、转化等行为特征.结果表明,城郊部分菜地土壤重金属污染与农业生产活动有密切关系,其中重金属在土壤中的行为特征与土壤环境和重金属形态有关.

SUMMARIZATION OF HEAVY METAL POLLUTION IN SOME SOILS FOR VEGETABLE CULTIVATION IN URBAN AREAS

After generalizing the present researches of China,the paper analyzed the heavy metal elements,the pollution trend,the polluted city,the pollution source,and the pollution cause.In the meantime,it discussed the heavy metal behavior.The results show that the pollution in some soils for vegetable cultivation in urban areas is related with agriculture action,and the action of heavy metals in some soils is related with the surroundings of the soils and the nature of the heavy metal.
