城市生活垃圾向土壤释放重金属研究

THE RELEASE OF HEAVY METALS FROM WASTES ASSOCIATEDWITH URBAN HUMAN LIFE IN THE DUMP SOIL

以南京为例,研究了城市生活垃圾对堆放环境土壤中重金属元素含量(总含量、各形态含量)的影响及其量比关系．结果表明,重金属元素在土壤中的含量和形态分布特征受其从垃圾中释放率的影响．自垃圾堆放环境土壤中释放的重金属含量与其有效态部分含量正相关．

The plot of the rubbish associated with human daily life in Nanjing was systematically studied as on example. It is demonstrated that the contents of heavy metal elements and their speciations in the dump soil are related with the release of heavy metals from the rubbish. The contents of heavy metals bounded to their efficient phases are raised as the rise of contents of heavy metals released from the rubbish in the soil environment.
