In an article in the journal "Nature Biotechnology" researchers saythey’re developing plants that clean up mercury contamination. TheGreat Lakes Radio Consortium’s Lester Graham reports:

Old Mercury Resurfacing

A study to be published this month shows mercury, deposited in riversas long as forty years ago, is still getting into the food chain andcausing environmental and human health problems. The Great Lakes RadioConsortium’s Stephanie Hemphill explains:

New Study Disputes Mercury Risk

A new study from the University of Rochester has concluded that eatingocean fish with low levels of mercury doesn’t pose any serious healthrisks. The Great Lakes Radio Consortium’s Lester Graham has more:

Mass Balance Study Underway

For the past four years, scientists have been hard at work around Lake Michigan, taking hundreds of water, sediment, and air samples and analyzing the data. It’s part of a study like no other—the largest of it’s kind. And the results are expected to have world-wide applications. The Great Lakes Radio Consortium’s Wendy Nelson reports:
