Authorities have declared smog alerts for the second straight day in Lucas and Wood counties, and for the third straight in metro Detroit, based on forecasts of hot, sunny, and relatively windless weather.
Heat and sunlight accelerate re|actions between oxygen in the air and airborne pollutants released by vehicles, charcoal lighter fluid and solvents, gasoline-powered equipment, and other sources. The reactions create ozone, which is a lung irritant.
The Ozone Action! Day declaration asks people to avoid unnecessary driving, lawn-care activity with gasoline-powered equipment, and use of solvents to help curtail ozone formation. Refuel vehicles or equipment only in the evening. The Toledo Area Regional Transit Authority waives fares on such days to encourage bus ridership.
Reducing electricity demand by reducing air conditioning in rooms or buildings that will be unoccupied during the day also helps, as power plants release ozone-causing pollution too, the Toledo Metropolitan Area Council of Governments said.
The National Weather Service and Accu-Weather, Inc., a private forecasting firm based in State College, Pa., predict sunshine, light winds, and highs in the 90s in the Toledo area today.
