PRESS RELEASE | High Pollution Advisory issued for ozone effective May 16, 2020 in the Phoenix area

The Arizona Department of Environmental Quality (ADEQ) is issuing a High Pollution Advisory (HPA) for ozone effective May 16, 2020, in the Phoenix area. ADEQ recommends that people limit outdoor activity while the HPA is in effect, especially children and adults with respiratory problems. Ground level ozone forms when two types of pollutants—volatile organic compounds (VOCs) and nitrogen oxides (NOx)—react in sunlight. These pollutants come primarily from automobiles, but also from other sources including industries, power plants, and products, such as solvents and paints. Generally, the highest levels of ozone occur in the afternoon.

Exposure can increase the number and severity of asthma attacks, cause or aggravate bronchitis or other lung disease and reduce the body’s ability to fight infection. Symptoms may include itchy eyes, nose, and throat, wheezing, coughing, shortness of breath, chest pain and upper respiratory issues. Please help reduce ozone by doing one or more of the following: Drive as little as possible Re-fuel your vehicle in the evening Avoid waiting in long drive-thru lines, if possible Use low-VOC (Volatile Organic Compounds) or water-based paints, stains, finishes and paint strippers – delay big painting projects Make sure containers of household cleaners, garage and yard chemicals and other solvents are sealed properly to prevent vapors from evaporating into the air Be Air Aware!
