Abstract: The aim of the present work is to investigate the distribution of arsenic (As) in sewage irrigation area, to deduce the migration and transformation mechanism of As in soil and groundwater, and to infer the source of As in soil and groundwater. This study is carried out in a sewage irrigation area of the Pearl River Delta, China. Surface water samples, soil samples, and groundwater samples from sewage irrigation area were analyzed for As and other elements. As contents in water samples were analyzed by hydride generation-atomic fluorescence spectroscopy, and As fractionation in soil samples was extracted using a seven-step sequential extraction method according to a seven fraction scheme: water soluble, ion exchangeable, bound to carbonate, weakly bound to organic matter, associated with oxides of iron (Fe) and manganese (Mn), strongly bound to organic matter, and the residual fraction...
