Want to talk about air quality in Salt Lake City, which by Wednesday may be the worst in the nation?

Political reporter Robert Gehrke will moderate a live TribTalk video chat at 12:15 p.m. Tuesday featuring Cherise Udell of Utah Moms for Clean Air, Matt Pacenza of HEAL Utah and Robert Grow of Envision Utah.

Gehrke will fill in as TribTalk moderator for Jennifer Napier-Pearce, who will be moderating a Martin Luther King Day-related discussion at the University of Utah.

During TribTalk, participants will discuss results of a new Salt Lake Tribune poll that found Utahns want tighter regulations on industry and are willing to change their own habits to improve air quality.

You can join the discussion by sending questions and comments to the hashtag #TribTalk on Twitter and Google+, or submit comments in the comment section of this story.

Meanwhile, all The Tribune's air-quality coverage is available here.

Also, plan on attending a special town hall planned Jan. 29 at 7 p.m. in the auditorium at the Salt Lake City Main Library, 210 E. 400 South, during which a panel of experts will address your questions.

Our town hall partner KCPW 88.3/105.3 FM will broadcast the event live. Napier-Pearce will be the moderator.

We've created a Facebook event page about the town hall that includes more information. Check it out, let us know if you're coming and invite others to join in as well.
