DENVER -- The Colorado Health Department and Regional Air Quality Council issued an ozone action alert for metro Denver and the Front Range on Thursday.
Bright sun, hot temperatures and light winds are combining to create high ground ozone conditions.
Emissions from everyday things such as gas-powered vehicles and lawn mowers, paints, and other solvents combine with other pollutants to create ground-level ozone pollution. It can cause health issues for children and the elderly, and people with respiratory issues.
Sara Goodwin with OzoneAware.org said people can cut down their ozone emissions with simple steps such as reducing car trips and mowing their lawn or refueling their cars in the evening. The alert goes through 4 p.m. Friday.
The smoke-filled haze that's in the air is from wildfires in other parts of Colorado and around the region.
