Margaret Karagas Quoted on Arsenic Levels in Baby Food
Dartmouth Superfund Research Program researcher Margaret Karagas is quoted in a New York Times article on levels of inorganic arsenic in infant rice cereal and cereal made from other grains. Although manufacturers have succeeded in reducing the amount of inorganic arsenic in these products, Dr. Karagas is concerned that, "It's just like lead: we don't think there is a safe level.
Paper Published on Exposure to Methylmercury and Inorganic Arsenic in Rice in Baby Food and Teething Biscuits
According to the paper Co-exposure to Methylmercury and Inorganic Arsenic in Baby Rice Cereals and Rice-Containing Teething Biscuits co-authored by Dartmouth Superfund Program researcher Brian Jackson, it is still possible to purchase rice baby cereals with elevated inorganic arsenic concentrations in the U.S. In addition, all rice baby cereals and teething biscuits that were tested contained methylmercury, a potentially important dietary source of postnatal methylmercury exposure. The researchers conclude that studies concerning their individual and combined impacts on children's health and development are warranted.
High Levels of Arsenic in Water in Maine
According to a new U.S. Geological Survey report, Maine has one of the highest arsenic levels in both bedrock and well water. A letter to the editor in the Portland Press Herald explains why more needs to be done to ensure that families have access to clean drinking water.
Free Arsenic Testing of Residential Wells Offered in Rockport and Camden, ME
The Camden and Rockport Conservation committees are offering 150 free arsenic well tests to community members with residential well water. According to the Maine Center for Disease Control, one in five Knox County wells has too much arsenic. Extended exposure to arsenic has been linked to lung, skin and/or bladder cancer, low birth weights and can affect brain development. More information.
Mercury-Safe Tuna Company Mission to Clean Up Oceans
Through its fish-by-fish testing system, Safe Catch claims the lowest mercury concentration of any canned tuna company. Now, it wants to use its wealth of data to tackle the source of the contamination. Sean Wittenberg and a small team raised millions of dollars to develop a technology that could test a fish in seconds for a fraction of the current costs. More information.
Study Shows EPA Mandate On Arsenic Has Helped Drinking Water Quality
According to articles in Water Online and NIEHS Environmental Factor, a new study published in The Lancet Public Health journal, purports that federal efforts in the US to limit arsenic in drinking water has prevented hundreds of cases of lung and bladder cancer every year. While the mandate seems to have been effective for those served by public water systems, those served by private wells are likely still vulnerable.

Concerns About Gluten-Free Diets for Children Without Celiac Disease
An article in U.S.News raises questions about children who do not have celiac disease or non-celiac gluten sensitivity eating gluten-free diets. There is particular concern about rice as a substitute for gluten since it can contain naturally occurring inorganic arsenic. Exposure in utero or in early life can raise the risk of cancer and affect neurological development, among other negative effects. A study published in February found that Americans on gluten-free diets had higher concentrations of arsenic and mercury in their urine and blood than people on a regular diet, possibly from rice consumption. According to Dartmouth Superfund Program researcher Tracy Punshon, it's unclear whether that translates to health problems for adults or for children, who are more vulnerable to contaminants because of their developing brains.
Many Maine Families Can't Afford to Treat Well Water
An estimated 100,000 people in Maine have well water that is contaminated by arsenic. Prolonged exposure to arsenic has been linked to learning disabilities, cognitive problems, anxiety and depression, and cancer. Since many families cannot afford to treat their well water to remove arsenic, legislation has been passed to help lower income Maine residents. It is not known whether Governor LePage will sign the bill. More information.

13th International Conference on Mercury as a Global Pollutant (ICMGP) Science to Policy Synthesis Workshop
On July 16, thirty scientists and policy stakeholders attended a day-long workshop, Integrating Mercury Research and Policy in a Changing World, as part of the ICMGP 2017 meeting. Organized and led by the Dartmouth SRP Research Translation Core, the workshop provided the opportunity for face-to-face communications between mercury science experts and national and international policymakers and stakeholders. Presentations by policymaker and stakeholder representatives identified questions and knowledge gaps in mercury research to be addressed in a series of 4 synthesis papers on different aspects of mercury pollution. The workshop culminated with a full-group discussion on how to translate these synthesis papers to have a bigger impact on mercury policy. A more detailed summary and photos are available here.
