A high pollution advisory is in effect across metro Phoenix through Monday, the Arizona Department of Environmental Quality announced.
It is recommended that residents — especially children and adults with respiratory problems — limit outdoor activity while the advisory is in effect.
Exposure to air pollution can increase the number and severity of asthma attacks, cause or aggravate lung diseases and reduce the body’s ability to fight infection.
In an effort to reduce pollution levels, ADEQ is asking the public to drive as little as possible, carpool, avoid refueling cars during the day, avoid long drive-thru lines, delay large painting projects and keep household cleaners and chemical products sealed to prevent evaporating vapors.
According to the department, the highest levels of ozone occur in the afternoon.
Symptoms of pollution exposure may include itchy eyes, nose and throat, wheezing, coughing, shortness of breath, chest pain and upper respiratory issues.
