关于表层土壤重金属含量测定方法探讨

Discussion on determination method of heavy metal content in topsoil

在人类的生产生活过程中,土壤是非常关键的。当前由于工农业快速发展,城市化进一步深入,造成了非常严重的环境污染问题,一些化肥、农药、重金属都是土壤污染的源头,尤其是重金属污染物,其具有富集性,生物累积性,通过大气沉降、污水灌溉农田等方式向土壤当中渗入,导致土壤理化性质改变,对人体的健康产生了直接或者间接的影响,本文重点分析表层土壤重金属含量测定方法,以供参考。

In the process of human production and life,soil is very critical.At present,with the rapid development of industry and agriculture and the further deepening of urbanization,serious environmental pollution problems have been caused.Some chemical fertilizers,pesticides and heavy metals are the sources of soil pollution,especially heavy metal pollutants,which have the characteristics of enrichment and bioaccumulation.Infiltration leads to the change of soil physical and chemical properties,which has a direct or indirect impact on human health.This paper focuses on the analysis of surface soil heavy metal content determination methods for reference.
