Project Summary (2000-2006)

The Geochemistry Core Laboratory is housed at Lamont-Doherty Earth Observatory (LDEO) and provides sample preparation and analyses to the research projects. Sample preparation includes the following matrices: water, soil, sediment and pre-ashed blood. Analyses include stable lead isotope ratios on pre-ashed blood samples and soil samples, total arsenic concentrations for soil samples, As concentrations in drinking water, concentration and speciation of arsenic in water and sediment samples, and concentrations of redox-sensitive elements (e.g. Sb, Fe, Mn, U, Mo, Cd) in the same matrices. Additionally, radionuclide measurements via gamma spectroscopy are being performed on sediment cores.
