Abstract: This paper aims to understand the current situation of heavy metal pollution in paddy soil in West Guangxi, to provide a reference for heavy metal pollution control. The content of Cd, Pb and As of 50 soil samples of cultivation layer (0-20 cm), taken from main rice producing areas in West Guangxi, is determined. The environment quality of soil is assessed with the single factor index and the potential ecological risk of paddy soil is evaluated with the potential ecological risk index of Hakanson. The results show that the mean content of Cd, Pb, and As in paddy soil samples is 0.941, 26.46 and 10.16 mg/kg, respectively. The Cd content of 54.0% soil samples and the As content of 2.0% soil samples are higher than the standard II National Soil Environment Quality, and Cd in paddy soil has high potential ecological risk. Heavy metal pollution in paddy soil in West Guangxi is mainly Cd pollution.
