Environment Quality Assessment of Heavy Metals in sediment along ChaoHu Lack

CaoDeju1 et al.(1.College of Resources and Environment,AnHui Agriculture University,HeFei 230036;2.Department of Environment Monitor of AnHui ChaoHu,ChaoHu 238000)  
This paper through the research of sediment from nine places along the lake of chaohu,which study the quantity of Cu,Pb,Mn,Zn,Cr,Cd in sediment and analyze the phase of dissolvent by water,exchangeable and weak oxide effective distribute situation in it.The results show that: Zn、Mn、Cr in sediment along the chaohu lake is high,It's pollution to lower and middle grade.But Cd,Pb、Cu is clean in most area.From the analyze of phase of heavy metals can get : weak acid effective exchangeable dissolvent by water.Particularly the phase is weak oxide effective heavy metal of Pb is higher,and the phase of exchangeable is lower.The weak acid effective of Mn、Cu is also higher.The phase of dissolvent by water of the six heavy metal element is small.
