This Federal Register notice provides EPA's rationale for the 1999 revisions to the Air Quality Index used by States for daily reporting to the general public in accordance with section 319 of the Clean Air Act. This short, colorful pamphlet tells who is at risk from exposure to ozone, what health effects are caused by ozone, and simple measures that can be taken to reduce health risk. This factsheet provides information about ways to protect your health when ozone levels reach the unhealthy range, and ways you can help reduce ozone air pollution. This is a 40 minute video developed by EPA and the University of North Carolina School of Medicine for physicians and other primary care providers. It describes the physiological mechanisms responsible for the symptoms, lung function changes, and pulmonary inflammation associated with exposure to ground-level ozone.
Information is provided about additional effects of ozone on people with asthma.
This report was used to develop the 1999 revision to the Air Quality Index.
