In the U.S., people of color live, on average, in more polluted neighborhoods than whites, according to new University of Minnesota research.
Researchers say thousands of deaths could be prevented each year if the racial disparity is reduced.
The University study, released earlier this month, found that non-whites are more likely to live in areas with higher concentrations of nitrogen dioxide, which increases the risk of respiratory illness, heart disease and other diseases. The pollutant comes mostly from vehicle exhaust and power plants.
