AUGUSTA – Ground-level ozone concentrations are expected to reach unhealthful levels in southern coastal sections of the state Wednesday. Pollution will combine with sunny skies, hot temperatures and southerly winds to push concentrations above the federal health-based air quality standard, according to the Department of Environmental Protection.

Individuals suffering from a respiratory disease, such as asthma, as well as children and healthy active adults can experience reduced lung function and irritation. Symptoms include shortness of breath, coughing, throat irritation and uncomfortable sensations in the chest, said a DEP press release.

Actions that can help reduce adverse effects on health include:

. Avoiding strenuous activities at midday.

. Closing windows and circulating indoor air with a fan or air conditioner.

. Avoiding use of aerosol products such as cleaners, paints and other lung irritants.

Actions that help reduce emissions contributing to the formation of ozone include:

. Conserving electricity.

. Commuting another way: carpooling, walking or using public transportation.

. Refueling cars and trucks and using gas-powered lawn and garden equipment after dusk.

. Reducing trips.

. Using environmentally safe paints and cleaning products.
