چکیده
A field survey was conducted to investigate the heavy metal contamination of paddy soils in Xiangyin County, China. The total concentration of Cd, Pb, Zn, Cu, Cr and Ni in paddy soil was measured, and the environmental quality of paddy soil was assessed using pollution index methods. Paddy soils were slightly polluted with the content of Cd exceeding the standard value. The moderately polluted soils were mainly distributed in the land-reclamation area from Dongting Lake, and slight pollution was found in the eastern hilly area.
