Source-Specific Air Pollution Emissions Inequalities From 2011 to 2020 in Virginia.

ABSTRACT: Air quality has improved in recent decades across most of the United States. However, decreases in pollution have not been uniform, potentially exacerbating inequalities in air pollution exposure by race and ethnicity. These inequalities exist, in part, because of spatial differences in source(s), for example, power plants or roadways. Determining which sources are driving inequality across racial and ethnic groups is critical to determining which policies (e.g., targeting power plant vs. vehicle emissions) would reduce inequalities. Our study determines which pollutant sources should be decreased to address inequalities in four pollutants (NO_x, SO₂, VOCs, and PM_2.5) in the Commonwealth of Virginia. We derived emissions from eight source categories for 134
