How air pollution plays a role during Arizona’s deadliest months of the year

PHOENIX (AZFamily) — Maricopa County has declared Monday through Wednesday as ‘no burn days.’ County leaders say there are elevated levels of smoke in the air.

The poor air quality was visible in the Valley Monday as the Arizona’s Family news drone captured video of the layers of pollution. It could be seen from Camelback Mountain through downtown Phoenix.

It’s common to see the dirty air this time of year. There are more people visiting Arizona through the holidays, which means more cars and more air pollution.

There are also more people burning inside to heat their homes, which sends smoke into the air. People will also light off fireworks around the holidays, which can add to the already poor air quality.

While the weather is beautiful around the Valley this time of year, it can be the deadliest time in Arizona. According to numbers from the Arizona Department of Health Services, January is the deadliest month of the year.

In 2022, more than 8,300 people died in Arizona, nearly 2,000 more than any other month. December was second-highest, with more than 6,700 people who died.

Air pollution could be a contributing factor to the increased deaths in our state.

Dr. Ashley Lowe with the College of Nursing at the University of Arizona works with many Arizona schools. She says these months are when more kids are going to the nurse with breathing problems and says air pollution is a big reason why.

“We do tend to have an uptick in the number of visits to the health office because kids are having breathing problems,” Lowe said. “All of these things come together to create a perfect storm.”

Dr. Lowe says kids with asthma can especially be impacted from the dirty air. She says she doesn’t want kids to stay away from their practices and other events, but it’s best to limit exposure outdoors on some of the worst air quality days.

If you are struggling to breathe, shutting the windows and doors around your home can help by keeping the polluted air outside of your home.

An indoor air filter can also clean out the bad particles from the air inside your home.

The weather also plays a role in why the bad air can stick around for days or even weeks this time of year. While it’s beautiful outside, the weather is normally calm which means there is no wind or rain to push the dirty air away.

“We live already in a valley kind of in a bowl and everything kind of settles. You get warm afternoons and cold mornings so that inversion sets in and it kind of traps everything,” Arizona’s Family First Alert Meteorologist April Warnecke said. “It would help to get wind or rain but those are the two things we don’t have in the forecast.”

Air quality trackers can show where the worst of the polluted air is.

According to AirNow, Christmas and New Year’s can have the worst air quality of the year. There were readings of “very unhealthy” air quality during the holidays in 2023.

The CDC says chronic respiratory disease is the fifth leading cause of death in Arizona each year.
