Determination and Environmental Impact Review on Heavy Metals Pollution in Soils of Bilateral Highway
HUANG Ming-xia(Heze University,Heze,Shandong 274000)
[Objective]The purpose of this research was to review the heavy metals pollution degree in soils of bilateral highway.[Method] Cd、Cr、Ni、Pb and Cu in soils of bilateral highway were determined with microwave digestion and ICP-AES,and Cd,Cr,Ni,Pb and Cu pollution degree were appraised by using terra accumulate exponential method.[Result] The results indicated that along with interval from highway straight line distance were more and more,the content of the Cd,Cr,Ni,Pb and the Cu were less and less in the sample point's soil,the content of Cr,Ni,Pb and Cu all had obvious ascension,but it did not overstep the second class standard of the environment quality of soil.Cd pollution severity oversteped the third class standard of the environment quality of soil.[Conclusion] This research will provide the scientific references for fathering heavy metals pollution in soils of bilateral highway.
