| 摘 要： | 采集粤北仁化和乐昌铅锌矿周边稻田土壤,分析土壤砷含量和土壤基本理化性质,初步研究土壤砷含量与土壤基本理化性质的关系。结果表明,矿区周边稻田土壤砷含量范围为3.73-120.00 mg/kg,平均值为30.40 mg/kg。其中仁化铅锌矿周边稻田土壤砷含量范围为3.73-20.00 mg/kg,乐昌铅锌矿周边稻田土壤砷含量范围为53.70-120.00 mg/kg。矿区周边稻田供试土壤砷含量与土壤pH值、EC、CEC及粘粒、有效硅、游离铁、游离锰含量均呈极显著正相关。

| Abstract: | The soil was collected from paddy fields around Renhua and Lechang lead(Pb) and znic(Zn) mines in north Guangdong for analyzing the arsenicum(As) content and basic physico-chemical property of soil,then the relationship between As content and basic physico-chemical property of soil was studied preliminarily.The results showed that the content range and average content of As in soil of paddy fields around mining areas were 3.73-120.00 and 30.40 mg/kg resp.;among them the content ranges of As in soil of paddy fields around Renhua and Lechang Pb and Zn mines were 3.73-20.00 and 53.70-120.00 mg/kg resp.The As content in tested soil of paddy fields around mining areas showed extremely significant and positive correlation with pH value,EC,CEC,cosmid,available silicium,free ferrum and free manganum in soil. |
