Samuel J. Traina

Using a wide range of analytical methods (infra-red spectroscopy, electron microsocpy, x-ray absorption spectroscopy and mass spectroscopy), Professor Traina's group studies:

• Chemical transformations of pollutants in soils, surface and ground water
• Linkages between chemical form or speciation of particular pollutants and their relative toxicities in terrestrial and aquatic ecosystems
• Roles of geoparticle surfaces and bacteria in pollutant fate

Current projects include the study of:

• Contaminants at Department of Energy waste sites (Cr, Pu and U)
• Role of Fe(II) and HSe- in transformations of nitroaromatic pesticides in wetlands
• Fate of pharmaceuticals in the surface waters of National Parks
