Persistent inequitable exposure to air pollution in Salt Lake County schools

Salt Lake County, Utah’s air pollution varies over the year, and at times it is the worst in the United States. The geography traps winter inversions and summertime smog throughout the Salt Lake Valley, but underserved neighborhoods — and their schools — experience the highest concentrations. A new study utilized a community-university partnership of nearly 200 PM 2.5 sensors through the Air Quality and U network and revealed persistent social inequalities in Salt Lake County schools.
