Final Progress Reports
The Trace Element Analysis Core (TEAC) provides low level detection, speciation, and localization of superfund contaminants in environmental samples, foods, cells, exposure media, and other matrices. The TEAC analyzed 5344 samples (04/01/20-02/28/20), 815 of which were from Dartmouth Center researchers. The TEAC collaborated with other Superfund programs including a sub-contract with the new Harvard Center and analysis for the University of Washington Center for arsenic speciation.
The TEAC Leader, Brian Jackson, Ph.D., and Co-Leader, Tracy Punshon, Ph.D., received SRP Administrative Data Supplements in 2019. Jackson led the Dartmouth Internal Use Case focused on improving data storage infrastructure by establishing a database for all TEAC data. Dartmouth Research Computing are constructing the database and this work will continue into 2021. The team expects to begin populating the database with existing data in 2021 and bring it on-line for storing new data. Data will be searchable and will operate under FAIR (Findable, Accessible, Interoperable, Reusable) principles, subject to individual project privacy requirements. Punshon has an External Use Case Supplement with Ben Bostick, Ph.D., of the Columbia University SRP Center to bring FAIR principles to synchrotron data. Student James Gibson worked with Punshon to establish a Biological Elemental Imaging Database consisting of over a decade of model plant elemental images from Mary Lou Guerinot, Ph.D.’s, Arsenic Uptake, Transport and Storage in Plants Project. The database is currently being piloted as a within-laboratory resource to bug check and improve data and metadata quality, before being launched as a publicly accessible resource that can accept data from other researchers.
