Abstract

To identify the concentrations and sources of pollutants and also to assess the soil environmental quality, a total of 2 400 topsoil (0–20 cm) samples and 10 subsoil (180–200 cm) samples were collected in Gannan area in the northwest Songnen-Plain. Then 6 major elements, 18 trace elements, pH, and C.org (organic carbon) were analyzed. The accumulation of Cd, Cu, Pb, Zn, Hg, and F was apparent in the agricultural soils. Correlation coefficient analysis showed that most major and trace elements, as well as pH and C.org, were significantly positive correlated in agricultural soil. Principal component analysis (PCA) indicated 2 main anthropogenic sources for trace elements in agricultural topsoil : 1) a mixture of atmospheric deposition and livestock manures; 2) the inorganic fertilizers and lime, as well as agrochemicals. Spatial distribution patterns using GIS contour maps and an integrated soil pollution index were established for the selected metal concentrations. It is highlighted that more attention should be paid to metal pollution of agricultural soil
