The state has issued an Air Quality Action Day in the Pittsburgh region.

Elevated levels of ozone mean that people who are sensitive to air pollution — such as children, the elderly and asthmatics — should avoid extended time outdoors today, according to the Pennsylvania Department of Environmental Protection.

Everyone is asked to help reduce pollution by carpooling, refueling vehicles after the sun sets, not mowing lawns and conserving electricity by only running full loads of laundry or dishes.
