Final Progress Reports

Year:   2020  2016  2010  2005 

Over 3000 samples of groundwater, as well as about 1500 samples analyzed for QA/QC purposes (standards, blanks, replicates), were analyzed by high-resolution inductively coupled plasma mass spectrometry for projects operating in Bangladesh and the U.S. These projects include all six projects from Columbia University's Superfund Research Program. With support from the Biogeochemist Core Laboratory, Ezazul Haque, a MS trainee, was able to increase the accuracy of dissolved arsenic measurements with a field-kit by analyzing image of the test strip, Haque et al. (2016). The data generated under the Biogeochemist Core Laboratory contributed to several published health and geoscience studies, including those by Mason Stahl, Ph.D., Ivan Mihajlov, and I. Choudhury. The Biogeochemistry Core Laboratory has also supported the analysis of several hundred sediment samples by XRF-fluorescence for a study of high arsenic levels in paddy soil on rice yield by Ph.D. student Brittany Huhmann.
