Category: Air Toxics Current & Ongoing 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.
Current & Recently Completed Studies
Ethylene Oxide Study EPA’s latest National Air Toxics Assessment identified ethylene oxide as an air toxic pollutant of emerging concern, with potential to lead to elevated cancer risk. To determine any potential health risk from exposure to ethylene oxide in Utah communities, the Division of Air Quality and the University of Utah will measure ambient …
A study conducted by the Utah Division of Air Quality (UDAQ) and the University of Utah, where 24-hr time-integrated air samples were collected every third day at three different sites during 2015, showed high levels of formaldehyde and dichloromethane at Bountiful Viewmont (BV) site.
