Abstract

The migration of arsenic and uranium at the Ningyo-Toge environments was studied. Laboratory experiments and synchrotron XAFS analysis showed that in natural sedimentary environments, arsenic is adsorbed and coprecipitated on iron (hydr)oxides, such as ferrihydrite and goethite, limiting their behavior in the hydrosphere.
