The Arizona Department of Environmental Quality has issued an ozone high-pollution advisory for Friday.

No relief from heat this week

A high-pollution advisory is issued when ozone levels are expected to exceed federal standards. Ozone is an invisible pollutant formed with other pollution, such as nitrogen oxides from cars, when heated.

The extreme heat baking the Valley is expected to rapidly increase the level of ozone, perhaps through the weekend, according to ADEQ.

Ozone can aggravate the lungs and can lead to coughing or chest pain. People with existing respiratory disease, as well as active adults and children, should reduce outdoor activity Friday. Motorists are asked to car-pool or telecommute to minimize additional impact from vehicle exhaust.
