Superfund Research Program
Project Leader: Bruce A. Stanton
Grant Number: P42ES007373
Funding Period: 2000-2020
All trainees, students and postdoctoral fellows supported by individual projects participate in Core activities including: bi-monthly meetings, individual presentations of their research to all project personnel, participation in annual trainee program retreat and presentations at scientific meetings. Monthly informal lunch meetings were initiated in the fall of 2011 to improve communication between trainees and the core PI and co-PI on ideas for training initiatives. Trainee 'chalk talks' will start up in winter 2011. The Training Core provided direct financial support to three graduate students (GS) and five postdoctoral fellows (PD) this year.
Training Core Supportees:
- Samuel Beal: 3rd year GS Earth Sciences. Project: Atmospheric and climatic controls on atmospheric metal deposition to southern Peru and Yukon Territory. Research examines atmospheric inputs of trace metals to natural systems, determining natural versus anthropogenic contributions, and putting current inputs in context of historical ones. Progress: Developed a record of total Hg deposition to Denali Massif, Alaska, between 2007 and 2009 using snow pit samples. Presented at SRP Annual Meeting: "Atmospheric deposition of Mercury to snow on Denali, Alaska between 2007 and 2009"
- Christine Palmer: 5th year GS (completed) Biological Sciences. Project: Transcription factors involved in the Arabidopsis Fe deficiency response, functional characterization of genes involved in As accumulation in Arabidopsis.
- Vivien Taylor: PD Trace Element Analysis Core. Projects: (1) Developing novel techniques for determining low-level Hg and As species; (2) market basket study of As in infant formula, and (3) studying Hg species in porewater downstream of a Superfund site. Progress: published two first-author papers. Presented at the annual Dartmouth Superfund Day and the Annual SRP meeting.
- Jie Yang: GS Earth Sciences. Project: Partitioning of Hg in stream sediments at the Berlin Superfund site and comparing the size-fractionation and solid phase binding of Hg at this site with 'control' sites in New England to investigate whether there are intrinsic differences between point source and non-point source Hg contamination.
- Diane Gilbert-Diamond: PD Dartmouth Medical School (DMS). Project: Fetal exposure to As and its effects on birth outcomes. Progress: First-author publication in PNAS on As exposure via rice in the New Hampshire Birth Cohort.
- Emily Notch: PD DMS. Project: Effect of As on Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) in the gill of Atlantic Killifish (Fundulus heteroclitus) Progress: Publication in PLoS One. Attended the SRP Annual Meeting in Kentucky and presented a poster entitled "Morpholino Gene Knockdown in Adult Fundulus heteroclitus: Role of Serum Glucocorticoid Kinase 1 in Seawater Acclimation."
- Dawoon Jung: PD DMS. Project: The role of aquaglyceroporins (AQP 3, 7, and 9) in the As uptake pathway in Atlantic killifish (Fundulus heteroclitus). Progress: Part of this project was published recently. In addition, he presented his current work at the annual Society of Toxicology Conference in Washington, DC (March 2011) and the annual SRP conference in Lexington, KY (October 2011).
- Kate Buckman: PD Biological Sciences: Project: Bioaccumulation and trophic transfer of methylmercury. SRP Annual Meeting Poster Presentation: Increasing water temperature enhances methylmercury bioaccumulation in killifish (Fundulus heteroclitus).
