An Ozone Action Day has been called for Friday in the Baton Rouge area because hot and sunny weather with little wind means conditions are right for ozone pollution to form today, according to the Louisiana Department of Environmental Quality.
Ozone air pollution forms when nitrogen oxides and hydrocarbons from industry, car exhaust and many other sources combine in the air during hot and sunny days. Ozone pollution can cause breathing and other health problems, particularly for sensitive populations.
Industry and government agencies have plans to limit activities that can contribute to ozone formation on these days, such as putting off any painting, unloading of certain materials and lawn mowing. Residents are also asked to limit their driving and to mow grass and refuel cars in the evening instead of during the day.
