The Science Behind Air Quality Standards

  • Clean Air Scientific Advisory Committee (US) that reviewed 3,000 health studies conducted over the last 15 years before recommending the EPA adopt stricter air quality standards. Studies confirm a direct relationship between declines in air quality and increases in hospital admissions and emergency room visits for respiratory problems, especially among the young and the elderly.
  • The Natural Resources Defense Council's analysis of Harvard University data shows that soot in the air shortens the lives of 64,000 Americans annually
  • The Environmental Protection Agency (U.S.) is proposing stricter air quality standards because an overwhelming body of scientific evidence - more than 3,000 health studies - demonstrates that existing air quality standards do not adequately protect Americans' health from smog and soot
