Health Watch For Ozone Effective August 12, 2019 In  Phoenix Area

With only August 9th and 10th being the only dates this month without an alert, the week starts off with another Health Watch alert from Arizona Department of Environmental Quality.

The Arizona Department of Environmental Quality (ADEQ) is issuing a Health Watch (HW) for ozone effective August 12, 2019 in the Phoenix area. ADEQ recommends that people limit outdoor activity while the HW 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.

Health Impacts

People most vulnerable to the impacts of air pollution include children, older adults, adults exercising outdoors, people with heart or lung disease and those suffering from asthma and bronchitis. 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.
