Lead is a toxic metal that was once used regularly in motor fuel, paint, ceramics, glassware, and other consumer products. The phase-out of leaded gasoline significantly reduced vehicle emissions and lead levels in the environment, but it is still used in some aviation fuels and used or produced in a variety of industrial processes. The …

This study builds on last year’s effort to improve the speciation of volatile organic compound (VOC) emissions from oil and gas wells in the Uintah Basin. Better speciation profiles will yield a better emission inventory for the basin and will help focus emission reduction strategies.
This study, led by researchers at BYU, will use particulate matter (PM) sampling to identify regional dust sources that impact local air quality and public health, as well as model how dust sources might change in the future.

This study will test if satellite observations of vegetation and land use can be used to improve photochemical model performance in the Uintah basin. An improved model will help inform emission reduction strategies and regulatory action.
The TRAX air quality project continues to measure PM2.5 and ozone from TRAX light rail trains, and will add measurements to the Blue line. All data is publicly available and posted in near real-time on the MesoWest website.
This study will investigate the existing emission inventory of ammonia (NH3) sources and compare modeled NH3 concentrations to those observed during recent field studies in order to identify and correct missing NH3 sources. In addition to improving the inventory, this study will add new NH3 emission pathways to the photochemical model.
The University of Utah will make measurements of vertical wind and aerosol profiles, as well as ozone and fine particulate matter (PM2.5) concentrations at the mouth of Red Butte Canyon in order to better understand air exchange in the Salt Lake Valley during wintertime PM2.5 events.
This study will deploy a number of ozone sensors at different distances up Red Butte Canyon to better understand natural gradients in ozone and how phenomena like large thunderstorms and valley drainage flows contribute to ozone concentrations in the Salt Lake Valley.
