From the Washington Post:

Nearly every source of the nation’s most pervasive and deadly air pollutant disproportionately affects Americans of color, regardless of their state or income level, according to a study published Wednesday. The analysis of fine-particle matter, which includes soot, shows how decisions made decades ago about where to build highways and industrial plants continue to harm the health of Black, Latino and Asian Americans today.

The findings of researchers from five universities, published in the online journal Science Advances, provide the most detailed evidence to date of how Americans of color have not reaped the same benefits as White Americans, even though the country has made major strides in curbing pollution from cars, trucks, factories and other sources. The particles studied have diameters of no more than 2.5 micrometers — one-thirtieth the width of a human hair — and can become embedded in the lungs. Known as particulate matter (PM) 2.5, they account for between 85,000 and 200,000 premature U.S. deaths each year.

The new paper, coupled with two other analyses also released Wednesday, bolsters the argument that environmental advocates have made for years that Black, Latino, Asian and Native Americans bear a heavier burden. And this growing body of research is showing the full scope of the problem.
Black, Hispanic and Asian Americans face a higher level of exposure than average to PM 2.5 from industry, light-duty vehicles, diesel-powered heavy trucks and construction, while Black Americans are exposed to greater-than-average concentrations from all categories in the Environmental Protection Agency National Emissions Inventory. White Americans have slightly higher-than-average exposure from agriculture and coal-fired power plants, the analysis found, because of where both are located.
“The deck is stacked against people of color, for almost every emission source,” Joshua Apte, one of the authors and an engineering professor at the University of California at Berkeley, said in an interview. “The recipe we’ve had for improving air quality for the last 50 years, which has worked well for the country overall, is not a good recipe for solving environmental inequality.”
