Dragonflies Reveal Mercury Levels in National Parks

A citizen science program that began over a decade ago has confirmed the use of dragonflies to measure mercury pollution, according to a study in Environmental Science & Technology. The original project was launched by Dr. Sarah Nelson at the University of Maine and the Schoodic Institute in 2007. Dartmouth’s Toxic Metals Superfund Research Program developed a regional effort in New Hampshire and Vermont in 2010. The project was expanded nationally by the National Park Service and the U.S. Geological Survey. More details on 10 years of citizen science mercury data using dragonfly larvae biosentinels!

SEPA Scientists Talk Arsenic

MDI Biological Laboratory and Dartmouth College, in collaboration with multiple partners in Maine and New Hampshire, are leading an NIH Science Education Partnership Award (SEPA) project called: “Data to Action: A secondary school-based citizen science project to address arsenic contamination of well water.” SEPA Co-Leaders Jane Disney and Bruce Stanton will be interviewed by Voice of Maine News/Talk Radio about arsenic in well water, a significant problem for private wells in Maine and New Hampshire. Tune in Saturday 7/25 at 6:30 a.m. and 8 p.m on 103.9 FM (Bangor).

Dr. Celia Chen on New England News Collaborative

“As Trump Overhauls Mercury Regulations, Toxic Emissions Could Rise”: Check out Dr. Celia Chen interview on the New England News Collaborative show, NEXT, at 19:40 in the broadcast.  On April 16, 2020, the Environmental Protection Agency (EPA) overturned the Agency’s prior determination and deemed that it is not “appropriate and necessary” to regulate mercury and other hazardous air pollutants (HAPs) from oil- and coal-fired power plants under section 112 of the Clean Air Act. According to legal scholars, this decision undermines the foundation of the MATS rule and invites challenges to the emissions standards themselves.
