摘    要:以系统形态分析结合上浮水和悬浮物中砷的总量及形态分布特征,评价了黄河(内蒙古段)水体中砷的潜在危害程度.结果表明,水和悬浮物中砷的总含量出现了比较一致的沿河变化趋势,说明水中的砷主要是泥沙携带的砷,水中含砷量的高低取决于水中悬浮物即泥沙的含量.悬浮物中的砷以Ca-As为主,O-As次之,其它三种形态砷的含量均很低,与黄土中各形态砷的含量比较接近,进一步说明了黄河水体中的砷主要来源于自然界.

关 键 词:黄河  悬浮物    形态

Abstract:The numerous experimental researches were carried out on chemical forms of arsenic in the water and suspened solid to assess pollution characteristics of arsenic in the Inner Mongolia section of the Yellow river. Based on the experimental research, the tolal contents of arsenic in the water and suspened solid showed the same trend, that illustrated that arsenic in the water mainly originated from the suspended solid. The content of arsenic in the water was decided by the content of suspened solid in water. Arsenic in the suspended solid is dominated by Ca-As secondly by O-As, the contents of the rest three species were very low, the speciation distribution was very similar to that of loess, tion of the Yellow river was mainly originated that showed arsenic in the water body of the Inner Mongolia secfrom nature.
Keywords:Yellow river  suspended solid  arsenic  speciation
