Pollution control policies effective in improving downwind air quality

Emissions controls on coal-fired power plants are making a difference in reducing exposure of mercury to people, especially in the western Maryland community. A study of air quality from the University of Maryland Center for Environmental Science found that levels of mercury in the air from power plant emissions dropped more than half over a 10-year period, coinciding with stricter pollution controls.
