‘Fingerprinting’ method tracks mercury emissions from coal-fired power plant
For the first time, the chemical “fingerprints” of the element mercury can directly link environmental pollution to a specific coal-burning power plant. “We see a specific, distinct signature to the mercury that’s downwind of the power plant, and we can clearly conclude that mercury from that power plant is being deposited locally,” said U-M researcher Joel Blum.

Acid rain threatens Great Lakes sugar maples
Because they grow in calcium-rich soils, sugar maple forests in the Great Lakes region have largely been spared the damage caused by acid rain in the Northeast. But now, U-M ecologists has uncovered a different and previously unstudied mechanism by which acid rain harms sugar maple seedlings in Upper Great Lakes forests.
