A citizen science program that began over a decade ago found that dragonflies can be used to measure mercury pollution. Research Professor Celia Chen, director of the Dartmouth Toxic Metals Superfund Research Program, explains the national research effort, which grew out of a Dartmouth-related regional project to collect dragonfly larvae.

“It’s a potentially important way for us to determine whether national and international policies on mercury management are effective,” Chen said. “A dragonfly such as a” biosentinel “or bioindicator may be a very useful tool for determining change across the landscape as well as changing over time.”
