Manmade mercury emissions decline 30 percent from 1990-2010

Between 1990 and 2010, global mercury emissions from manmade sources declined 30 percent, according to a new study by the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), Peking University, the U.S. Geological Survey(USGS), the Max Planck Institute for Chemistry, and the University of Alberta. These results challenge long-standing assumptions about mercury emission trends.
