Can air pollution harm only lungs?
Decades of research have led scientists to understand the links between air pollution and serious health effects. Although early research focused on health effects to the lungs, recent research has revealed that the air we breathe may contain contaminants that are harmful to other organs such as the heart and brain or biological systems. Evidence from new research links air pollution to cardiovascular disease and even death. EPA research continues to investigate the many health effects that can result from exposure to air pollution. Science produced the Clean Air Research Program provides the foundation for much of our knowledge about the health outcomes of air pollutants, particularly ozone, PM, and other common air pollutants. 2. Why study indoor air quality? Americans spend 90 percent of their time indoors where pollutant levels can frequently exceed those found outdoors. This is because indoor air can include outdoor pollutants that seep inside as well as pollutants from indoor sou
