Seniors, small children and people with asthma or other respiratory illnesses should limit their exposure to the outdoors Thursday because the region is under a Level Orange ozone watch.
The Texas Commission on Environmental Quality issued the watch for the second consecutive day, saying atmospheric conditions would be ripe for producing levels of ground ozone that could be harmful for sensitive groups.
On Wednesday, Dallas-Fort Worth reached the Level Orange warning stage for the third day this year. That means more than 75 parts per billion of ozone pollutants were measured.
Level Orange air quality standards were also exceeded on March 24 and 25.
For motorists who want to do their part to clean up the air, it's a chance to think about finding an alternative way to get to work, officials said.
"We're asking people to do something to help air quality," said Amanda Wilson, spokeswoman for the North Central Texas Council of Governments.
"If they can, think about taking transit or carpooling or packing a lunch to work so they don't have to drive at lunchtime."
On Friday, Fort Worth Mayor Betsy Price is scheduled to ride her bicycle to work along with other cycling enthusiasts. It's part of the Fort Worth Transportation Authority's annual Bike to Work Rally, 7-9 a.m. at the Intermodal Transportation Center downtown.
