|WEDNESDAY, MAY 24 - AIR QUALITY INDEX AND OZONE ACTION!
To report ozone pollution levels to the public, the EPA uses a color-coded "Air Quality Index."
"Green" means good air quality; "yellow" moderate; "orange" unhealthy
for certain sensitive groups; and "red" just plain unhealthy for
To help get the word out when ozone pollution reaches unhealthy levels,
about 200 local businesses, organizations, and government agencies have
banded together to form the Ozone Action Partnership. When unhealthy
ozone levels are forecast - that is, code "red" - the Partnership
declares what's called an "Ozone Action! Day."
This serves two purposes. First, it's a health notice, especially for those most vulnerable to ozone, such as children, adults who work outdoors, and people with asthma. Second, an Ozone Action! Day is a call to everyone to try and reduce the build-up of ozone. And tomorrow night I'll offer a few suggestions on how you can help do that.
