DENVER — It is another Ozone Action Day Alert for the Front Range, and an air quality warning is in effect until at least 4 p.m. Wednesday for the Denver metro area, west to the foothills, north to the Wyoming border and over portions of the northeastern plains. So what exactly does that mean for you and your family?
Ozone is a chemical compound that impacts life on earth in both good and bad ways. The ozone layer is high above the planet and blocks U-V radiation from the sun. That’s a good thing, we need that. There is also ground level ozone that we breathe, which occurs from a chemical reaction of things like exhaust and pollutants that mixes with sunlight. This can be harmful.
Vehicle emissions and industrial activities also create contaminants. On Ozone Action Day Alerts, the Colorado Department of Public Health and Environment requests we limit driving gas- and diesel-powered vehicles. Opt to carpool, take public transportation, walk, or ride a bike if possible.
