Superfund Research Program
Trace Elements Analysis Core
The Trace Element Analysis Core (TEAC) has analyzed about 4,000 samples and supported all Dartmouth Superfund Research Program (SRP) projects, the Community Engagement Core, and the Research Translation Core (RTC) during this funding cycle. For example, the TEAC collaborated with the Arsenic and Innate Immunity in Human Lung Project and the RTC on a study of the efficacy of table-top water filters to remove arsenic from drinking water. The TEAC published the results with brand names, so consumers could make an informed choice. The TEAC collaborated with other superfund centers and regional NIEHS-funded programs to provide analysis of contaminants in human biomarker samples. The lead researcher oversees a Superfund pilot project focused on legacy mercury contamination at a Superfund site in Berlin, New Hampshire. The project's trainee, Livia Capaldi, presented preliminary results at the SRP Annual Meeting. The lead researcher gave three invited talks on "Arsenic in the Food Supply" and spoke at the University of Rochester Symposium on "Current Approaches to Exposure Assessment in Environmental Health Sciences." The TEAC continue to study arsenic and mercury in food and collaborated on a study on rice-based food marketed for infants and young children. The Agilent 8800 ICP-MS has been upgraded to the 8900. The latter provides greater sensitivity, better interference removal, and faster measurements, which provides significant benefits to Dartmouth SRP's Superfund projects and keeps the TEAC at the forefront of elemental analysis technology.
