| Abstract: | Base on the agro-ecological geochemical survey of east Shandong Province, the differences of geochemical background values and baselines of 54 elements or indicators in soil between the study region and China were studied. Most of the elements or indicators of the surface soil were inherited from the parent material, with limited human influences. Meanwhile, obvious changes were found in the distributions of Zn, Pb, Cu, Se, Cd, S, P, Hg, N, OrgC, etc in surface soil, which may be attributed to the hypergenesis or human activities. The assessment and identification method on the enrichment of heavy metals in soil caused by human activities were discussed through the comparison of elements correlation relationship between surface and deep soil. Several heavy metals, Hg, Cd, Pb, As, Zn, Se, S, etc, were strongly enriched in surface soil in Laizhou-Zhaoyuan-Yantai and Muping-Rushan gold field and populated area in cities. The comparison study between soil elements distribution in typical vertical profile and geological background indicates that the enrichment of heavy metals in surface soil profile in some regions of eastern Shandong Province may be attributed to the geology background and human activities （gold mine, industrial activities, urban emissions, etc）. |
