...AIR QUALITY ALERT IN EFFECT THROUGH FRIDAY NIGHT...
The Illinois Environmental Protection Agency has determined that an
Air Pollution Action Day will be declared for the greater Chicago
Metropolitan Area and is IN EFFECT THROUGH FRIDAY NIGHT.
An Air Pollution Action Day is declared when weather conditions are
such that widespread ozone and or particulate levels are expected to
be at or above the Unhealthy for Sensitive Groups category of the
Air Quality Index for multiple days. Ozone is expected to be the
primary pollutant of concern, but fireworks emissions may also
contribute to higher AQI readings for both PM2.5 and Ozone at times.
Active children and adults, especially people with pulmonary or
respiratory disease such as asthma, should limit prolonged outdoor
activity.
Area residents are urged to reduce pollution levels. Air quality
forecasts, current air quality, and tips on how you can reduce your
emissions can be found at www.airnow.gov.
