摘要
The results of agro-ecological geochemical survey and evaluation of eastern Shandong Province are presented. The results indicate that contents of Zn, Pb, Cu, Se, Cd, S, P, Hg, N, Org C, etc. are strongly present. In summary, the geochemical environment quality is good on the basis that only 0.13% of the total are Ⅲ type and worse than Ⅲ type soils, in which are adjacent to mining areas and cities. However, Cd, Cr, Ni, and Hg were worse than the quality standards. The main reasons for enrichment of heavy metals in parts of the study area were human activities, such as mining, urbanization, industrialization, and geological background weathering.
