Abstract
X-ray Absorption Near Edge Spectroscopy (XANES) was applied to give arsenic chemical form directly in the solid phase of creek sediment and mine waste samples from the Woodcutters Mine site. The XANES fitting data can be compared with existing bioaccessibility and bioavailability (rat animal uptake) data to explain the observed compositions of the mine wastes. The XANES results support that when soil intake was adjusted for bioaccessibility the potential risk estimate to local residents from the mine waste is less significant. © 2012 Taylor & Francis Group.
