Marginalized communities, especially those with higher-than-average minority populations, are more likely to be exposed to air pollution in the U.S., according to new research.
In 2016, the average concentration of fine particulate matter to which Black populations were exposed was 13.7% higher than that affecting white populations and 36.3% higher than that affecting Native American populations, according to the study.
Researchers from Harvard University combined pollution data with the census data from 2000 and 2016, which included information such as zip codes and median household income, to find out how pollution exposure levels varied across different racial and ethnic groups, Abdulrahman Jbaily, a former postdoctoral research fellow at the Harvard T.H. Chan School of Public Health and co-author of the study, told ABC News.
