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!
