WASHINGTON- The Environmental Protection Agency announced a new standard for air quality aimed to reduce pollution. The agency predicts this strengthened standard will prevent up to 4,500 premature deaths and avoid an estimated 800,000 cases of asthma symptoms. It targets soot which is one of the most dangerous types of air pollution. Soot is emitted from cars, trucks, buses, construction sites, and more.
