Description:
Arsenic in soils from the Asarco lead smelter in East Helena, Montana was characterized by X-ray absorption spectroscopy (XAS). Arsenic oxidation state and mineralogy were analyzed as a function of depth and surface distribution using bulk and microprobe XAS. These results were compared with data from macroscopic scale desorption/dissolution experiments. The experiments focused on the effects of phosphate and pH on the desorption/dissolution of As.
