Urban Air Toxics Network (UAT)

 The NC Division of Air Quality (DAQ) operates the urban air toxics (UAT) monitoring network in conjunction with the national program, originally proposed and designed by the U.S. EPA in 1999. The UAT monitoring network was started as part of the EPA's effort to address toxic air pollutant emissions in urban areas.

Currently, the UAT consists of seven sites, six urban and one rural. UAT air monitoring is regularly conducted for volatile organic compounds (VOCs). Monitoring for selected aldehydes are conducted on a more limited basis at three sites.
