Progress Reports

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

Aims: The goal of the Trace Element Analysis Core is to provide state of the art analytical resources and expertise to Dartmouth Superfund projects. The TEA Core also adds value to the projects by providing method development and therefore allowing new avenues of research.

Studies and results: The TEA Core had no carry-over funding during the no cost extension, consequently no specific studies were conducted during this time period except for a prior obligation to the Dartmouth CEC to analyze ca. 80 dragonflies for methylmercury and total mercury for a local high school project.

The Core PL was invited to speak at the annual Food and Nutrition Conference and Expo in Houston in October 2013. The session was on Arsenic in rice and Dr. Jackson was one of two speakers. Attendees provided feedback on the session to the FNCE academy and the session was very well received.

Significance: The work of the TEA Core on arsenic in food continues to contribute to the growing calls from scientists and consumers for regulatory guidelines or limits on inorganic arsenic in foodstuffs.

Plans: Contingent on a successful renewal of the Dartmouth program, The TEA Core will work with the Arsenic Epidemiology, Biomarkers and Exposure Assessment of Metals project to develop methods for the determination of arsenic in breast milk and for the elemental mapping of arsenic in placenta, and to speciate arsenic in lung epithelial cells. The Core will pursue further determinations of arsenic in foods with a focus on rice-based gluten-free foods. The Core will also continue to work with the Arsenic as an Endocrine Disrupter project in the application of enriched isotopic mercury tracers to study mercury biogeochemistry.
