| Abstract: | Based on dates in 2001-2008,the heavy metal contents in benthos in the Dalian bay are analyzed and assessed.The results show that:Zn>Cr>Cu>Cd>As>Pb>Hg.The mean datas of 2006-2008 compared with those of SHIWUperiod,the heavy metal contents in benthos are declining.The pollutions of heavy metals in benthos are slight,but the concentration of Cd,Cr,Zn,Hg,Cu is serious.The contents of Cd are beyond the standard for human consumption and this problem should be noticed by departments. |
