Abstract

Abstract

The investigation of redox-sensitive elements characteristics and 3D fluorescent spectroscopy to groundwater from JiangHan plain, were conducted to understand the biogeochemical mechanisms of arsenic mobilization. Groundwater geochemistry indicates that the occurrence of arsenic is closely associated with the geochemical processes of Fe (Ⅲ) reduction and organic matter oxidation. The fluorescent spectroscopy characterization of dissolved organic matter (DOM) shows that the reactive organic matters mediating oxidation-reduction reaction prevail in groundwater and arsenic mobilization is linked with the microbes-mediated reductive dissolution process of iron (hydr)oxides, in which DOM components are probably involved in the process electron shuttle and thus enhance arsenic mobilization through catalyzing the oxidation-reduction process.
