Research Projects Overview
The State of Utah is home to towering mountain ranges, resource-rich basins, sprawling farmland, and vast deserts. These diverse environments are inhabited by equally diverse people, all of whom are affected by the air quality in our state. Understanding the factors that influence the quality of our air is imperative to mitigating the harmful effects of poor air quality on public health. The physical environment which includes atmospheric chemistry, meteorology, and topography, combines with by-products of modern technology and industry such as emissions from vehicles and buildings, to create air pollution problems that are unique to Utah. Research conducted by the Division of Air Quality and its community partners informs decisions made by the Utah State Legislature to improve our air quality.
Air Toxics
Current Studies
The Environmental Protection Agency (EPA) has identified 187 hazardous air pollutants (HAPs) that are associated with numerous adverse health effects including cancer and neurological, reproductive, developmental, and other health problems. These pollutants come from a wide variety of industrial, residential, and mobile sources and the health risk exposure thresholds associated with them are continually updated according to the most current toxicological and epidemiological research. The following studies, including ongoing as well as future projects, have been undertaken to gain a better understanding of the concentration and sources of these pollutants.

Mobile Source Emissions
Current Studies
Reducing automobile emissions has been a central component of the state’s plans to improve air quality. The start cycle of vehicles is known to have increased emissions of hydrocarbons (HC) and carbon monoxide (CO) because the engine uses an enriched fuel mixture to avoid misfires due to condensation on the cylinder walls. The following studies quantify the impact of different vehicle starting methods at low temperatures on Utah’s wintertime air quality.

Model Improvements
Current Studies
Air quality models are used to predict atmospheric conditions in the future. They are based on meteorological conditions, chemistry mechanisms, and inventories of reported emissions. Models are tested for correctness by comparing their results to observed atmospheric characteristics, such as PM2.5 concentrations during high pollution periods in the past. The following studies show various ways in which models are being improved to better reflect observations of the atmosphere in Utah.

Uinta Basin Oil and Gas
Current Studies
The Uinta Basin, a structural basin located in the remote northeastern corner of the state of Utah, is the main oil and gas development hub in the state. It has unique atmospheric chemistry regimes during the winter that create ozone concentrations that sometimes exceed those in the largest U.S. cities. The following studies have helped the Division of Air Quality better understand the complex atmospheric conditions of this region.
