Air Quality Action Days
Ground-level ozone smog and particulate matter (soot) pollution can cause breathing problems. While high levels of ozone (smog) occur on hot, sunny days with little wind, particle pollution can reach unhealthy levels in hot or cool weather.
When air quality is deemed “unhealthy,” it is important for people in sensitive groups such as children, the elderly and people with lung disease to limit strenuous activity and stay in a temperature-controlled environment (such as an air conditioned building).
It is also important for everyone to limit their polluting activities on days with unhealthy air quality. People can help limit pollution levels by carpooling, not mowing the lawn and using less electricity.
To be informed of days when poor air quality is predicted, sign up for EnviroFlash alerts sponsored by the U.S. Environmental Protection Agency.
