The Indiana Department of Environmental Management (IDEM) was forecasting
high ozone levels on Thursday for Northwest Indiana, including Porter
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.
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 encourages everyone to help reduce ozone by making simple changes to
their daily habits:
•Walk, bike, carpool or use public transportation.
•Avoid using the drive-through and combine errands into one trip.
•Avoid using gasoline-powered lawn equipment.
•Turn off your engine when idling for more than 30 seconds.
•Conserve energy by turning off lights or setting the air conditioner to 75
degrees or above.
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
