Air Quality and American Culture on Friday's Access Utah

Utah State University/Utah Division of Air Quality

Cache Valley air quality has been getting a lot of attention the last several years.  A few days a year, usually in the wintertime, the air pollution in Logan is worse than most other U.S. cities.  On Friday's AU, Sheri Quinn talks to Utah State University environmental engineer Dr. Randy Martin about his current research on the major air pollution culprit, PM2.5  

Then, Science Questions explores the Smithsonian Institution's "artifacts that define America" with the Smithsonian's Undersecretary for History, Art and Culture, Richard Kurin.
