Science & Policy Must Remain Partners in Mercury: Dartmouth SRP Director Co-Authors Opinion Article on Mercury Science & Policy from COP-3 in Geneva

Dartmouth Superfund Research Program Director Celia Chen co-authored an opinion article on the importance of the partnership between science and policymaking for the successful implementation of the 2017 Minamata Convention on Mercury, as she participates in the third meeting of the Conference of the Parties (COP-3) in Geneva Switzerland. The Op-ed appears in the Inter Press Service News Agency and focuses on the importance of the decisions COP-3 delegates will make at the November 25-29 meeting in Geneva on measuring the effectiveness of the Minamata Convention in reducing environmental mercury. These decisions are especially important due to the numerous adverse health effects of mercury. Dr. Chen represents Dartmouth College as a member of COP-3’s Policy Advisory Group on the Fate and Transport of Mercury. COP-1 Information



Rice Intake and Emerging Concerns on Arsenic in Rice: a Review of the Human Evidence and Methodologic Challenges

Dartmouth Superfund Research Program (SRP) researchers Margaret Karagas (lead author) and Tracy Punshon are co-authors of the paper Rice Intake and Emerging Concerns on Arsenic in Rice: a Review of the Human Evidence and Methodologic Challenges. The paper, which was published in the journal Current Environmental Health Reports, summarizes “…the state of the epidemiologic evidence on whether rice consumption relates to health outcomes associated with arsenic exposure.” The  article recommends that “further studies are needed to understand the health impacts of arsenic exposure from rice consumption taking into account all sources of rice intake and potential confounding by other dietary constituents or contaminants and arsenic exposure from sources such as water.”

Mercury Continues to Pose Threats to Human Health

According to a news story on the UN Environment Programme website, mercury continues to “…endanger human and environmental health…” Tackling this problem by comprehensively addressing mercury throughout its lifecycle is the goal of the Minamata Convention on Mercury which is taking place November 25-29 in Geneva, Switzerland. Dartmouth SRP Director and researcher Dr. Celia Chen will be attending the Convention and will be representing Dartmouth on the Policy Advisory Group (PAG) on Fate and Transport of Mercury.

Dartmouth SRP Researchers Present at SETAC Annual Meeting in Toronto

Dartmouth Superfund Research Program researchers Drs. Celia Chen and Tracy Punshon presented at the session, “Contaminant Mixtures in Food: How Did They Get There and Should We Be Concerned,” at SETAC’s (Society for Environmental Toxicology and Chemistry) annual meeting in Toronto. The objective of the session, which was co-chaired by Drs. Chen and Danielle Carlin of NIEHS (National Institute of Environmental Health Sciences), was to provide further understanding of the relationship between inorganic and organic contaminants in different food sources, novel statistical approaches to addressing the co-occurrence of contaminants in food, assessment of the potential health effects of mixtures, and strategies for prevention of exposures. Dr. Punshon, an invited speaker, presented a talk on “Carrageenan as a Source of Arsenic, Lead and Cadmium in Infant Foods.” Dr. Chen presented the poster “Patterns of Mercury and Metal and Organic Contaminants in Marine Fish and Shellfish.” Other session speakers included Drs. Wendy Heiger-Bermays from Boston University, Claire O’Brien from UC Davis, Julia Gohike from Virginia Tech, Jordan Smith from Pacific Northwest National Laboratory, Dr. Sarah Rothenberg from Oregon State University,  and Julia Bauer, Ph.D. Candidate, from Oregon State University. Meeting program.


NIEHS Story on Key Role of Dartmouth SRP in Reduction of NH Arsenic MCL

The Dartmouth SRP Center is featured in a NIEHS (National Institute of Environmental Health Science) website story on the signing into law of NH legislation to lower MCL (Maximum Contaminant Level) for Arsenic from 10 ppb to 5 ppb. The story describes how our SRP research, partnership,  Research Translation and Community Engagement activities informed the passage of the legislation. NIEHS write up.

Dr. Gary Ginsberg SRP Visit and Seminar on Emerging Contaminants

Gary Ginsberg, Ph.D., Director NY State Department of Health’s Center for Environmental Health and Professor at Yale University, met with our Dartmouth Superfund Research Program team and several trainees to discuss risk assessment and toxicology regarding emerging contaminants, including PFAS and 1-4 Dioxane. Dr. Ginsberg also participated in lunch-time conversation with our state partners from the VT Department of Health and NH DES (Department of Environmental Services) and NH DHHS (Health and Human Services) to discuss issues of mutual concern pertaining to emerging contaminants and PFAS in particular. More than 50 people attended an afternoon seminar Dr. Ginsberg gave on “The Challenge and Opportunities Presented by Emerging Contaminants.”


Many NH Public Water Systems Out of Compliance with New 2021 As Standard

According to an NHPR (NH Public Radio) story, recent testing data indicates many NH public water systems likely will not be in compliance with the state’s new arsenic in drinking water standard of 5 ppb that will go into effect in mid-2021. According to Paul Susca of NHDES (Department of Environmental Services) Drinking Water Bureau, state officials are working with potentially affected water systems on how they can be in compliance with the new limit. The new standard, which is lower than the federal standard of 10 ppb, was enacted because of the linkage between arsenic exposure and illnesses such as lung and bladder cancer and elevated risks of cardiovascular and developmental problems. The NHPR coverage cites research by Dartmouth’s Superfund Research Program on the large number of private wells that will exceed the 5 ppb standard, as well as a study on the increased risk of bladder cancer.  Although the new standard does not apply to private wells, private well owners are encouraged to comply with the new limits due to the health risks of As in drinking water, according to Paul Susca.

Dartmouth College SRP Receives Wellborn Foundation Grant for Dragonfly Project

Dartmouth College has received a grant of $5000 from the Wellborn Foundation for our Superfund Research Program’s Dragonfly Project. The Dragonfly Project involves working with high school science classes in NH and VT to collect dragonfly larvae for mercury testing. The Project is part of our effort to educate students about “…mercury in our world and the importance of clear, data-based scientific research and communication to mitigate mercury risks.” More information on the grant.

SEPA Project Promotes Data Literacy, Increasing Private Well Water Testing for As

SEPA project “Data to Action: A Secondary School-Based Citizen Science Project to Address Arsenic Contamination of Well Water” is aimed at promoting both data literacy and increasing rates of private well water testing for Arsenic in participating communities. Funded by the National Institute of General Medical Sciences (NIGMS) at the National Institutes of Health (NIH), it is being implemented by Dartmouth SRP in partnership with the Mount Desert Island Biological Laboratory.  Bruce Stanton (Project 3 Leader) is a co-PI. SRP researcher Kate Buckman is the project’s NH school coordinator.

Communicating Arsenic’s Risks

Dartmouth Superfund Research Program Director Celia Chen, former Dartmouth Superfund Research Program Community Engagement Core (CEC) Leaders Shannon Rogers (lead author) and Mark Borsuk, current Research Translation Coordinator Laurie Rardin, and former CEC Coordinator Kathrin Lawlor are co-authors of the paper Communicating Arsenic’s Risks. The study describes “two types of environmental communication efforts that have been undertaken by the Dartmouth Toxic Metals Superfund Research Program (DTMSRP)-the development and evaluation of a comprehensive website, Arsenic and You, and a mental models research approach to better understand the disconnect between expert and community perceptions of arsenic risk.” The paper is published in International Journal of Environmental Research and Public Health.
