Smog returning to Puget Sound region

 

Aug. 10, 2004 – Warm air aloft is trapping pollution at the surface and will bring smog back to our region between now and the end of the week. We expect air quality to deteriorate at least to Moderate and possibly Unhealthy for Sensitive groups on the Air Quality Index.

While the Smog Watch is in effect, you can help minimize the build up of pollution in the air we breathe by taking some or all of the following actions:

• Reduce driving by combining trips, carpooling, using public transportation and deferring errands.
• Avoid using gasoline-powered yard equipment.
• Refuel your automobile in the cooler, evening hours.

The highest concentrations of ground-level ozone (smog) (external link) happen when sunlight "cooks" emissions from motor vehicles, paints, solvents and gasoline vapors. Fine particulate levels also could rise into the Moderate level and affect visual air quality.

You can check current air quality conditions and forecasts at our Web site, www.pscleanair.org. You can also monitor ozone concentrations at nine sites by checking our Ozone Right Now Web page between May and September at www.pscleanair.org/airq/aqiozone.aspx.
