Bruce Stanton Radio Interview on SEPA Project January 14, 2019
On January 14, 2019, Dartmouth SRP researcher Bruce Stanton will be interviewed by Carol Higgins Taylor of Voice of Maine radio on the SEPA (Science Education Partnership) "Data to Action: A secondary school-based citizen science project to address arsenic contamination of well water" project. The project is funded by a SEPA award Dartmouth SRP and MDI Biological Laboratory in ME received from the NIGMS (National Institute of General Medical Sciences) of the NIH.
2019 NH Arsenic Consortium Meeting: Friday, March 22
The next NH Arsenic Consortium meeting will be on Friday, March 22 (weather date March 28), 2019!! Mark your calendars and plan to attend to help us fill in the Roadmap to Reduce Arsenic Exposure in NH.
NHDES Releases Recommendation for Arsenic Maximum Contaminant Level
The New Hampshire Department of Environmental Services released a two-part report to the State Legislature detailing their rationale for reducing the state MCL (maximum contaminant level) for arsenic from the current federal standard of 10 parts per billion (ppb) to 5 ppb. More details are available in the reports and the press release and media coverage pertaining to Dartmouth Superfund input on the report is available here.
Update on EPA Coal Plant Mercury Emissions Rule-Proposed Changes in Rulemaking
Dartmouth Superfund Research Program Director and Researcher Celia Chen is quoted in several media stories raising concerns about the US EPA's (Environmental Protection Agency) proposal to "change the way the federal government calculates the costs and benefits of dangerous air pollutants, arguing that authorities should exclude some of the public health benefits stemming from new rules."

Mercury Matters 2018
A Science Brief for Journalists and Policymakers
Mercury Matters 2018 is a summary of the latest information on mercury research on health and environmental effects, improvements occurring since the adoption of the Mercury and Air Toxics Standards (MATS), and evidence of the health benefits from mercury reductions.
SRP Researchers' Paper Chosen as Paper of the Month
NIEHS has chosen the paper Intrauterine Multi-Metal Exposure is Associated with Reduced Fetal Growth Through Modulation of the Placental Gene Network as one of its Extramural papers of the month. The study, co-authored by Dartmouth Superfund Research Program researchers Brian Jackson and Margaret Karagas, "...provided a novel approach that integrated advanced bioinformatics and biostatistics methods to delineate potential placental pathways through which trace metal exposures might affect fetal growth."
SRP Annual Meeting Held in Sacramento, CA
The national SRP (Superfund Research Program) Annual Meeting was held November 28-30 in Sacramento, CA. This year's theme was "The Next Generation of Superfund Training, Translation and Research". The meeting was a great success and provided an opportunity to connect with colleagues old and new and celebrate Center-wide trainee accomplishments. Thanks to UC Davis, Berkley and San Diego Centers for the great hosting and the amazing Sacramento tree collection. Additional information .
Paper Published on Opportunities for Reducing Dietary Arsenic Exposure
Several Dartmouth Superfund Program researchers (Celia Chen, Mary Lou Guerinot, Brian Jackson, Margaret Karagas, Tracy Punshon, Vivien Taylor), as well as RTC Coordinator Laurie Rardin and Trainees Britton Goodale, Antonia Signes-Pastor, and Todd Warczak are co-authors of the paper Opportunities and Challenges for Dietary Arsenic Intervention . The Brief Communication paper discusses a framework for short-term interventions for reducing dietary arsenic exposure and is a product of C-FARR (Collaborative on Food with Arsenic and Associated Risk and Regulation) which brought arsenic and food scientists together with policy stakeholders for a workshop focusing on knowledge gaps and policy questions in 2015.
Paper Published on Methylmercury (MeHg) Levels in Water Column and Estuarine Food Webs
Dartmouth Superfund Research Associate Vivien Taylor is the lead author of a paper on the relationship between dissolved organic carbon levels and the level of MeHg concentrations in fish and invertebrates. The findings "suggest that increased inputs of MeHg and loss of wetlands associated with climate change and anthropogenic land use pressure will increase MeHg concentrations in estuarine food webs." The study Organic Carbon Content Drives Methylmercury Levels in the Water Column and in Estuarine Food Webs across latitudes in the Northeast United States is co-authored by Dartmouth Superfund Director and researcher Celia Chen, Research Associate Kate Buckman, Project co-PI Robert Mason and former Trainees Emily Seelen and Nashaat Mazrui.
Paper Published on Methylmercury (MeHg) Concentrations in the Lower Food Web
Dartmouth Superfund Program Research Associate Kate Buckman is lead author of a paper on methylmercury (MeHg) concentrations in the lower food web in the Mediterranean Sea. The study, Spatial and Taxonomic Variation of Mercury Concentration in Low Trophic Level Fauna from the Mediterranean Sea, which is co-authored by SRP Director and researcher Celia Chen, suggests that there are areas where MeHg concentration in low trophic level fauna is enhanced and "...can translate up the food web."
Paper Calls for Need for Mercury Science to Inform Global Policy
Dartmouth Superfund Research Program Director and researcher Celia Chen is the lead author on the paper A Critical Time for Mercury Science to Inform Global Policy. The paper discusses mercury science in relation to policy developments.
