Wildfire Smoke Chokes Northern Utah, Raises Pollution

Jul 6, 2018

Smoke from the Dollar Ridge wildfire in eastern Utah spread throughout northern and central Utah on Friday and raised particulate pollution.

 

Wildfire near the Strawberry Reservoir has so far burned 74 square miles.  A change in weather patterns carried the smoke to places as far away as Brigham City and Tooele. Air-quality monitors measured elevated pollution throughout northern and central areas of the state.

 

“This, unfortunately, has become our typical summer situation,” said Bryce Bird, director of the Utah Division of Air Quality. “And then, as the fire season picks up, it seems like there is always the availability of smoke to come into the valley — whether it’s from California, Oregon, Idaho or local fires here in Utah.”

 

PM2.5 is basically microscopic soot. During winter smog episodes, it primarily comes from vehicle engines, gas heaters and other forms of combustion. In the summer, heavy wildfire smoke is often to blame for high levels. The health impacts are the same in both seasons.

 

Current alerts about air quality being “unhealthy for people in sensitive groups” amount to advisories for the very young, the very old and people with heart and lung problems to consider taking precautions, since they are particularly vulnerable to pollution at these levels.

 

Bird said the protective steps people take during winter smog episodes are useful when pollution from the smoke is high.

 

“Whenever you’re breathing more deeply, more heavily, whenever you’re exercising, things like that, you’re bringing more particles into your lungs,” he said. “So, avoiding that exertion is really a good way to prevent the impacts from that air pollutant.

 

Bird also pointed out that the summer ozone season is here, too. It’s a different type of pollution, often described as being like getting a sunburn on the lungs.

 

He said everyone can help reduce both types of air pollution.

 

“Driving less, driving smarter … telecommute, use public transportation — those are all good ways that everyone can take part in reducing the concentrations by reducing the emissions that we produce as a society,” he said.
