Title: Assessment of Heavy Metal Pollution in the Farmland Soil of Jiutai County, NE China
Abstract: The representative surface soils (0-20cm) were collected from farmland of Jiutai County, Jilin Province, Northeast China, and concentrations of Pb, Cr, Ni, Cu, Zn and Cd were analyzed. The aims were to investigate the contamination levels and potential threat to agricultural products and human health. The results showed that Pb, Cr, Ni and Cu concentrations were beyond the background values of Jilin Province, while Zn and Cd were lower than the corresponding background values. The heavy metals were all not beyond the Second standard limits of Chinese Soil Environmental Quality, and the soil was moderately contaminated by Pb, Cr, Ni and Cu.
