title: Spatial-based assessment of metal contamination in agricultural soils near an abandoned copper mine of eastern China.
abstract: An investigation about metal contamination on agricultural soils was carried out near an abandoned copper mine in eastern China. Results showed the average concentrations of Cu, Pb, Zn and Cd in the 155 soil samples were 147, 53.8, 158, 0.32 mg kg(-1) respectively, which were 4.6-, 2.2-, 2-, 1.7-fold of the corresponding background value. According to the Chinese Farmland Environmental Quality Evaluation Standards for Edible Agricultural Products, it was found 18.4 % of the soils belonged to heavily and moderately contaminated soils.
