The Analysis Of Heavy Metal Pollution Of Roadside Soil In Harbin City

Interest in the levels of heavy metal pollution associated with roadtransportationhas risen in these years,Influenced by such transportation.The dust soiland vegetable on the roadside have accumulated a large amount of heavy metals,andbecome a potential danger.The pollution will bring direct or indirect threat to humanheath.This article takes the study to heavy metal pollution in the trash of highwayconstruction and operation in order to put forward some advices and to control thepollution,which has significantly realistic and scientific meaning.On the Study of soil of the three roadside in Harbin,53sorts of samples aregathered.on the analysis of300effective data, make the analysis and research to thecontact and spreading characters of heavy metals Cd,Cr,Cu,Zn,Pb and Ni thesesamples.Meanwhile,ecological risk of these heavy metals are valued,which providesreliable scientific basis of the environment pollution control,highway management andcity planning of Harbin.The results show that the relationship between the heavy metal various forms isquite obvious.Soil heavy metal different forms and the correlation between the amountare obvious.The influence of Soil pH value, organic matter and soil particle compositionof fine powders and viscous grain to soil heavy metal form bigger, this meet the mostprevious research form distribution law achievements and heavy metals.The sample soilis not polluted but some heavy metals are going to be polluted compared with nationalstandard. But compared with background value of Songnen plain, the sample soil ispolluted. If this situation is ignored.The soil(s) will devastation.The sample soil is instatus of middle ecological harm under potential danger method.The transportation andindustrial emissions of waste are the source of the heavy metals pollution on theroadside soil in Harbin.
