- Abstract:
-
As, Cd, Ni, Cr, Pb, organic matter and pH were monitored in the surface soil of the Bortala River. The correlation of five kinds of heavy metals: As, Cd, Ni, Cr, Pb in surface soil in the studied area and the soil organic matter and pH value was analyzed. The results show that average contents of 5 kinds of soil heavy metals such as As, Cd, Ni, Cr, Pb were 22.37, 52.52, 27.50, 0.48, 28.92 mg/kg, respectively, the average soil organic matter content along the Bortala River is 27 431 mg/kg. Soil pH value range from 6.5 to 7.5, with an average of 6.94. The correlation between soil properties and heavy metal contents in the study area is complex: Organic matter content is significantly correlated with contents of As, Cr, Cd and Pb. Organic matter is easy to form a complex with heavy metal ions, thereby reducing the heavy metal ion activity, resulting in increased heavy metal contents in soil. pH value show a negative correlation with the contents of As, Cd, Pb. With the increase of pH value, the contents of available As,Cd and content of available Pb in soil significantly reduced. By analyzing the correlation between soil organic matter, pH and heavy metals, it was found that soil organic matter and pH are the important factors affecting soil heavy metal contents.
