...AIR QUALITY ALERT IN EFFECT FROM 10 AM TO 8 PM CDT FRIDAY...
The St. Louis Clean Air Partnership has issued an air quality alert
for the St. Louis metropolitan area from 10 AM to 8 PM CDT Friday.
An Orange air quality forecast means that maximum ozone
concentrations are expected to reach levels that pose a health risk.
Adverse health effects increase as air quality deteriorates. Ground-
level ozone is an air contaminant which can cause breathing
difficulties for children, older adults, as well as persons with
respiratory problems.
Reducing outdoor physical activity is recommended. If it is a
regularly scheduled work day you are urged to consider
telecommuting, carpooling, or utilizing public transit. Avoid
excessive idling and do not top off when refueling motor vehicles.
The use of gasoline-powered lawn equipment should be reduced or
postponed until late in the day.
