Air Research
EPA's air research provides the critical science to develop and implement outdoor air regulations under the Clean Air Act and puts new tools and information in the hands of air quality managers and regulators to protect the air we breathe.
Health and Air Quality
Research has linked regulated air pollutants such as ozone and particulate matter (PM), to lung and heart disease and other health problems.
