摘要
以攀枝花市为例,初步研究了该市土壤中微量元素分布的地球化学特征及城市环境污染特征。因子分析结果表明,各层土壤中的元素可分为两类:一类是引起城市土壤污染的重金属元素,另一类则是以稀土元素为代表的微量元素。城市土壤微量元素污染的分布特征表明,该市土壤微量元素的污染与该市的采矿冶炼等工业活动有直接联系。
A case study from Panzhihua city, primary studies about urban environmental geochemistry of trace elements in the soil were carried out. The result of factor analysis showed that the elements in different layers of the soil could be divided into two clusters: one is heavy metal caused soil pollution, another is trace element such as REE. The distribution characteristics of trace metal pollution in the urban soil showed that soil pollution was influenced by mining and industrial activities in Panzhihua City.
