What is the most important achievement we've gained through air pollution management? What remains to be done to safeguard public health from air pollution?
Air pollution is one of the most important environmental health threats of our time, contributing to four of the five leading causes of mortality in the United States: heart disease, cancer, stroke, and chronic lower respiratory diseases. Air pollution such as particulate matter, nitrous oxides, sulfur dioxide, ozone, heavy metals, and other air toxics damage our airways, lungs, heart, and circulatory systems. Exposure to these pollutants increase hospitalizations and emergency room visits, time lost from school and work, and premature deaths due to cardiopulmonary disease.
The Clean Air Act (CAA) controls the emissions of pollutants from the most widespread sources of dangerous air pollution: coal-fired power plants, motor vehicles, heavy industry, and refineries. The Act has resulted in significant improvements in public health, including major reductions in blood lead levels nationwide and reductions in premature deaths, illnesses, and hospitalizations stemming from air pollution exposure. Yet despite advancements in pollution controls, as many as 175 million people in the US live in areas that exceed Clean Air Act standards for air pollution.
At a time when the US Congress seeks to limit the scope of the EPA, weakening its ability to regulate air pollution, PSR’s experts examine the public health importance of air pollution management: What is the most important achievement we've gained through air pollution management? What remains to be done to safeguard public health from air pollution?

In the 1990s there was a shocking discovery. After more than 20 years of
federal regulations aimed at reducing negative impacts of air pollution
and clearing skies above American cities, two major studies found that
the pollution that remained was still strongly associated with
mortality. Read more »

Energy is essential to our daily lives, and is the foundation of our modern, industrial society. But fossil fuels, which feed the energy appetite of our nation and that of most developed nations, cost our society dearly in terms of health, environmental, and economic impacts. Read more »
