Ozone in Tucson returns to harmful level for 3rd consecutive week

Air pollution in the Tucson metro area hit harmful levels on Monday, prompting an advisory from Pima County that residents should avoid intense physical outdoor activity. The air-quality announcement marks three consecutive weeks with such a warning in a summer marked by wildfires.

State forecasts for Tucson show that high levels of ground-level ozone, the air pollutant triggering the advisory, are likely to return on Tuesday as well, and county  Department of Environmental Quality officials said they may do so if the weather conditions are similar.

“Individuals who are especially sensitive to air pollution may experience shortness of breath, coughing, throat irritation, wheezing and breathing discomfort,” county officials said.

The advisory suggests limiting levels of exertion outside between noon and 6 p.m., especially for anyone sensitive to air pollution in general.

Ground-level ozone commonly comes from car exhaust, industrial and power plant emissions and volatile organic compounds, or hydrocarbons, that react with heat and sunlight, PDEQ said.

People who might be sensitive to ozone include children, adults who are active outdoors, people with respiratory diseases and certain individuals who have an unusual sensitivity to this particular pollutant, PDEQ said. Anyone feeling symptoms should seek medical attention, the advisory warns.

According to the advisory, intense physical outdoor activity also allows ozone to penetrate into parts of the lungs more likely to be injured.

PDEQ recommended the following actions to reduce adding to ground-level air pollution:
