Trib Talk • The science of air quality

The geography of Wasatch Front valleys presents unique challenges to cleaning up the air. But just how bad is air pollution and what are scientists still trying to learn?

In the first in a series of conversations about Utah air pollution Monday at 12:15 p.m. at sltrib.com, Jennifer Napier-Pearce will moderate a live TribTalk video chat with Division of Air Quality director Bryce Bird, University of Utah air quality researcher Kerry Kelly and BYU emeritus chemistry professor Delbert Eatough about new ways scientists are measuring the toxic ingredients in Utah's air which could lead to more effective ways of getting rid of the gunk.
