Anyone sensitive to poor air quality may be affected when
ozone levels are high. Children, the elderly and anyone with heart or lung
conditions should reduce or avoid exertion and heavy work outdoors.
IDEM examines weather patterns and current ozone readings to
make daily air quality forecasts. To learn more about ozone or sign up for
air quality forecasts, visit

Ground-level ozone is formed when sunlight and hot weather
bake vehicle exhaust, factory emissions and gasoline vapors. Ozone in the
upper atmosphere blocks ultraviolet radiation, but ozone near the ground is
a lung irritant that can cause coughing and breathing difficulties.
