| Notes | 45-1381/S paddy soil;heavy metal pollution;potential ecological risk;assessment;western Guangxi Objective】 The purpose of this investigation was to understand the status of heavy metal pollution in paddy soil in western Guangxi and provide references for heavy metal pollution control. 【Method】The contents of Cd, Pb, and As of 50 soil samples from cultivation layer（0-20 cm）, which were taken from main rice producing areas in western Guangxi, were determined. The environment quality of soil was assessed with the single factor index and the potential ecological risk of paddy soil was evaluated with the potential ecological risk index of Hakanson. 【Result】The mean contents of Cd, Pb, and As in paddy soil samples were 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 were higher than the standard II of the national environment standard quality for soils. Cd in paddy soil showed high potential ecological risk. 【Conclusion】Paddy soil in western Gua |
