Soil Geochemical element Contents Characteristics and Pollution Assessment in Pingyin County,Shandong Province
2010
Based on the systematic sampling and investigation on the soil samples(54 elements and ratios are determined from collecting one superficial sample per 1km~2 and combining them into one sample per 4km~2,collecting one deep sample per 4km~2 and combining them into one analyzing sample per 16km~2),this paper analyzes soil geochemical parameters,element abundance characteristics and environmental impact.The pollution of heavy metals and harmful elements in the soil was assessed according to the Nenerow Aggregate Pollution Index.As is stated above,we think that many elements and ratios in superficial soil contained matrix soil,and can be hardly effected by human activity.However,C,Cd,C1,Hg,P,N,S,Se and Corg are concentrated evidently, and distribution of elements contents was found obviously,which is mainly affected by human activities.
