Paddy and adjacent non-paddy soil samples from different physiographic regions of Bangladesh were analyzed for total arsenic (As) and a number of chemical elements (Al, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Mo, Na, Ni, P, Pb and Zn) to assess the geomorphological and biogeochemical regulation of As in Bangladeshi soils. The mobility and interplay of As in paddy soils from different physiographic regions were also assessed by using diffusive gradients in thin-films (DGT) under anaerobic conditions. This study reveals that As concentrations in Bangladeshi soils vary across the physiographic regions and are potentially linked to inputs of As contaminated groundwater. Significant biogeochemical relationships of As in the soils indicate a biogeochemical control on its occurrence in the soils.
