摘要
研究了浙江省14种主要土壤中砷的赋存形态和含量,考察了土壤中水溶性砷、钙型砷、铝型砷、铁型砷和闭蓄型砷与土壤本性的关系,得出了估算各种形态砷的方程式.
The contents and various forms of arsenic in 14 main soils in Zhejiang Province were investigated. The
total arsenic content of soils tested ranged from 1.89 to 21.22mg/kg and was 8.81mg/kg on an average.
Fractionation of As forms was carried out using a modified Chang & Jackson's procedure. It was found that
the percentage ranges of H_2O-As, Al-As, Fe-As, Ca-As, and occluded As (O-As) were 0.47％～7.39％,
0.47％～5.79％, 6.54％～34.5％, 5.29％～21.96％, and 47.29％～85.31％ respectively. A series of
equations for estimating various forms of arsenic using soil properties has been developed.
