五大连池火山矿泥重金属污染调查分析

The analysis of heavy metal pollution investigation of Wudalianchi volcano mud

通过对五大连池区域内火山矿泥30个样点中重金属元素含量调查分析表明,矿泥中重金属Hg、Cr、As、Cu、Zn、Ni、Pb均明显低于土壤重金属背景值,属安全级别,但矿泥中重金属含量又因人为输入性活动增加而呈上升趋势,因此,保护矿泥生存环境,减少耕地开垦,减少农田污染物排放,降低矿泥重金属污染十分必要。

Through the investigation of the content of heavy metals in the region of Wudalianchi volcano mud in 30 samples,the analysis showed that the heavy metals like Hg,Cr,As,Cu,Zn,Ni and Pb in mud were significantly lower than the background value of heavy metals in soil,which belongs to the security level. However,we found that the content of heavy metals increases in sludge due to the input activity. Therefore,it is necessary to protect living environment of slime,reduce farmland reclamation,reduce pollutant emissions and reduce the pollution of heavy metals in sludge.
