This short, colorful pamphlet tells who is at risk from exposure to particle pollution (also known as particulate matter), what health effects may be caused by particles, and simple measures that can be taken to reduce health risk.

This 8-page booklet provides more detailed information than "Ozone and Your Health" about ozone health effects and how to avoid them

As people get older, their bodies are less able to compensate for the effects of environmental hazards. Air pollution, like ozone, particle pollution (PM), and especially fine particle pollution (PM2.5), is most likely to affect the health of older adults.

Ozone, the main ingredient of smog, presents a serious air quality problem in many parts of the United States. Even at low levels, ozone can cause health effects. You can take simple steps, described in this pamphlet, to protect your health from ozone.
