Utah's Summer Smog Season Gets Underway

Utah Department of Transportation

Utah’s smog season is underway. Some call it Utah’s overlooked pollution problem.

Michelle Hofmann, a pediatrician and founder of the health advocacy group Breathe Utah, is used to hearing people complain about sooty pollution in the winter. But she says it’s harder for patients to grasp the impacts of ground-level ozone pollution, since it’s odorless and colorless.

“Immediately when you breathe it, it is potentially injurious to the lungs,” she says. “It has been likened to causing a sunburn on the lungs. They feel like it might be extreme heat that’s causing their chest tightness or difficulty breathing. It probably is some of that, but it is probably also ozone air pollution.”

Utah’s summer pollution season officially started on Thursday. The Utah Division of Air Quality has a smartphone app to track current ozone levels and a 3-day forecast. D-A-Q’s web page also has up-to-the-hour information and a daily email advisory. In addition, the Utah Health Department has a pollution-symptom tracker.

Hofmann says that helps people anticipate the times when ozone pollution is likely to become a problem for them.

“Really getting in tune with what the current levels will help individuals decide whether they are sensitive and at what level they are sensitive,” she says. “We have a current air-quality standard – a national standard of 75 parts per billion – and that may not be sufficiently protective of everyone.”

Hofmann advises doing intense outdoor activities before lunch and after dinner. Air-quality officials point out that people can also spare the air of needless pollution. One way is to drive less.

The DAQ is warning ozone will be building up over the weekend.
