Celia Chen Participates in Podcast on Mercury Emissions
Dartmouth Superfund Research Program Director and Researcher Celia Chen participated in a podcast on Mercury and air toxics and the EPAs proposed Mercury and Air Toxics Standards (MATS) rule. The podcast was done by breathific, which is a nonprofit organization founded by high school students to increase awareness about air quality.
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.
Bruce Stanton Radio Interview on SEPA Project
Dartmouth SRP researcher Bruce Stanton was interviewed by Carol Higgins Taylor on 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 NIH.
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."
Paper Published on Effect of Metal Contaminants on Growth and Functioning of Placenta
Dartmouth Superfund Program researchers Tracy Punshon, Brian Jackson and Margaret Karagas are co-authors of a paper that examines relationships between placental concentrations of cadmium (Cd), arsenic (As), mercury (Hg) and lead (Pb) and measures of placental growth and functioning as part of the New Hampshire Birth Cohort Study. Placental Metal Concentrations in Relation to Placental Growth, Efficiency and Birth Weight
Paper Published on Methylmercury (MeHg) Levels in Water Column and Estuarine Food Webs
Dartmouth Superfund Research Associate Vivien Taylor is the lead author of Organic Carbon Content Drives Methylmercury Levels in the Water Column and in Estuarine Food Webs Across Latitudes in the Northeast United States 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."
