Research Unravels Atmospheric Mysteries

July 7, 2015 9:00 am | by Univ. of Colorado Boulder | News | Comments

It’s been difficult to explain patterns of toxic mercury in some parts of the world, such as why there’s so much of the toxin deposited into ecosystems from the air in the southeastern U.S., even upwind of usual sources. But, a new analysis shows that one key to understanding mercury’s strange behavior may be the unexpected reactivity of naturally occurring halogen compounds from the ocean.

Bacterial Fight Clubs Discover New Drugs
