Ground-level ozone air pollution in the Colorado Front Range broke federal health limits this week, urging state officials to post million-visible “action day” alerts along highways and on phone apps, driving residents Reduced and in some cases encouraged to stay indoors.
So far, the Colorado Department of Public Health and Environment has issued five Ozone Action Day alerts, including this Tuesday, Wednesday, and Thursday. The agency expects 36 days to alert by the end of August.
Ozone levels are determined by the amount of chemical gas that enters the sun. Major front-range sources of these pollutants, called volatile organic compounds (VOCs) and nitrogen oxides, include petroleum and gas production, vehicles, solvents and paints, gas lawnmowers, and household items.
The health limit of ozone is 70 ppb. So far this year, levels reached 87 ppb in Platteville on March 19th and 82 ppb in Golden on Tuesday. A wildfire broke out in August 2020, causing ozone to rise to 90 ppb near the National Renewable Energy Laboratory in Golden.
Colorado has frequently ignored federal health standards for over a decade. Environmental Protection Agency officials are expected to reclassify Colorado as a “serious” offender last year and downgrade this status to “serious.”

Over the last three years, ozone levels generally peaked in the late 1980s.
“Currently, Colorado and most parts of the west are expected to be below average precipitation and above average temperature this summer. These conditions usually result in elevated ozone levels,” Bear said. Mr. says.
When the air is stagnant, ozone levels rise. He said wildfire smoke would raise ozone levels even further.

Although chemical is complex, smoke increases ozone under certain conditions. Very thick smoke can block sunlight and reduce ozone. The climate in Colorado and the West shifts to hotter, drier conditions, exacerbating ozone.
Will ozone decrease if people reduce their driving and wait for the gas tank to fill?
State health officials “know that Colorado can make a real difference,” but couldn’t say how much pollution could be prevented.
What are state leaders doing on this issue?
Poor federal health standards mean that Colorado must do more legally to reduce air pollution. State health officials say they can’t control days above 90 degrees and wildfires.
Colorado air pollution control authorities have ordered oil and gas companies to close valves to fix leaks and recently proposed measures to encourage employers to offer better transportation options to workers.
