Groundbreaking nationwide study finds that people of color live in neighborhoods with more air pollution than whites

A press release from the University of Minnesota: A first-of-its-kind study by researchers at the University of Minnesota found that on average nationally, people of color are exposed to 38 percent higher levels of nitrogen dioxide (NO2) outdoor air pollution compared to white people.

Nitrogen dioxide comes from sources like vehicle exhaust and power plants. Breathing NO2 is linked to asthma symptoms and heart disease. The Environmental Protection Agency has listed it as one of the seven key air pollutants it monitors. The researchers studied NO2 levels in urban areas across the country and compared specific areas within the cities based on populations defined in the U.S. Census as “nonwhite” or “white.”

The health impacts from the difference in levels between whites and nonwhites found in the study are substantial. For example, researchers estimate that if nonwhites breathed the lower NO2 levels experienced by whites, it would prevent 7,000 deaths from heart disease alone among nonwhites each year.

The study entitled “National patterns in environmental injustice and inequality: Outdoor NO2 air pollution in the United States” was published in the April 15 issue of PLOS ONE, a leading peer-reviewed scientific journal.

“We were quite shocked to find such a large disparity between whites and nonwhites related to air pollution,” said Julian Marshall, a civil engineering associate professor in the University of Minnesota’s College of Science and Engineering and co-author of the study. “Our study provides a great baseline to track over time on important issues of environmental injustice and inequality in our country.”...
