摘要

对湘潭市土壤、不同土地利用类型及不同土壤类型土壤重金属Cu

As污染现状进行了调查和分析。结果表明

湘潭市54个样本中镉、汞2种重金属属于重污染;铜、锌属于中污染;铬属于轻度污染;铅、砷属于尚清洁区。不同土地利用类型土壤中镉、汞污染严重

介于重污染与中污染之间

铅属清洁区或尚清洁区

其余介于轻度污染与尚清洁区之间。不同类型土壤中镉、汞污染严重

属重污染

锌属中污染

铅属清洁区或尚清洁区

其余介于轻度污染与尚清洁区之间。总之

湘潭市镉、汞污染严重

污染可能由工业三废、汽车尾气、化肥和污水灌溉造成的。

Abstract

The pollution status of soil heavy metals(Cu

and As) under different landuse types and different soil types in Xiangtan City was investigated.Results showed that for the 54 samples

pollution by Cd and Hg was in a heavy stage

pollution by Cu and Zn reached a moderate stage

pollution by Cr was in a light stage

and pollution by Pb and As were still in a proximity clean zone.For different landuse types

pollution by Cd and Hg was most serious

which was between medium and heavy pollution stages

pollution by Pb stayed in a clean zone or proximity clean zone

and pollution by other metals was in a slight or proximity clean zone.For different soil types

pollution by Cd and Hg were heavy

pollution by Zn was moderate

pollution by Pb was in a clean or proximity zone

and pollution by other heavy metals was between slight and proximity clean zones.As a whole

pollution by heavy metals of Cd and Hg is heavy in Xiangtan City

which is probably caused by the "three wastes"

automobile exhaust

fertilizer application

and sewage irrigation.
