Progress Reports

Year:   2019  2018  2017  2016  2015  2014  2013  2012  2011  2010  2009  2008  2007  2006  2005  2004 

The Trace Elements Analysis Core has analyzed samples for all Dartmouth SRP projects in support of their research goals. The Core has also participated in Proficiency tests organized by Brooks Rand Labs (mercury species in water and arsenic species in foods), Center for toxicology, Quebec (total metals in blood, urine, serum, hair), and the Centers for Disease Control and Prevention (arsenic species in urine) -- the objective being to provide third-party assurance of the ability of the Core to provide accurate and precise results.

The Core greatly improved the analytical infrastructure with the purchase of a triple quadrupole inductively coupled plasma mass spectrometer (ICP-QQQ). The new instrument was funded by Dartmouth SRP, Dartmouth College, Dartmouth Earth Science Department, Dartmouth Children's Center for Environmental Health and Disease Prevention, and Dartmouth's Norris Cancer Center. The ICP-QQQ provides significantly lower detection limits for all elements and is particularly relevant for Dartmouth's arsenic research. New analytical methodologies will be developed using the unique features of this new instrument.

Presentations

The Core PI, Brian Jackson, gave two talks for the New England section of the American Chemical Society at Woods Hole, Massachusetts and Dartmouth College, New Hampshire, entitled "Arsenic in the U.S. food and water supply". The talks were open to the general public, and both were well attended.
