Study on the Heavy Metals in Soil in Different Functional Zones of Ereen

Abstract

Using plasma emission spectrometer and atom atomic fluorescence spectrometry analysis and the heavy metals of the soil samples, which are scientifically collected in business zone, living zone, agricultural zone and industrial zone of Ereen. The results show that different functional zones of Ereen present different distribution characteristics of heavy metals in soil, As, Cd, Cu, Hg , Zn of industrial zone and Cd in business zone, living zone and agricultural zone are all exceed the national soil environmental quality standards. The content of heavy metals in upper soil is higher than in the subsoil in the study area, which shows that artificial external pollution input potential influence on the soil of Ereen. Agricultural zone of Ereen is less pollution, industrial zone is polluted seriously, commercial and residential both achieve the moderate pollution, thus should strengthen scientific control and governance.
