Green Heart Initiative
EPA is raising awareness of air pollution's role in cardiovascular disease. Since passage of the Clean Air Act in 1970, EPA scientists have been at the forefront of air pollution research to provide the scientific foundation for the nation's air quality standards. The research has helped to save lives and improve health. EPA is providing people the information they need to lower their health risk and live healthier lives.
Research by EPA and others has found the fine particles, an air pollutant known as PM2.5, are linked to heart disease. These particles are emitted through combustion from motor vehicles, power plants, industry and naturally from forest fires.
EPA researchers are expanding their efforts to investigate the effects of ozone and multiple pollutants on the heart and vascular systems. New research indicates ozone may also contribute to heart problems, including cardiac arrhythmia.
