Black Americans of all income levels exposed to more air pollution sources

People of color disproportionately affected by PM 2.5 in pretty much all states and all urban areas, study finds

Whether they're breathing factory fumes and truck exhaust in urban centers or choking on dust on rural farm roads, people of color face exposure to more sources of harmful fine particle air pollution than white people, a new, comprehensive national study shows.

A team of environmental researchers from universities across the US sought to find the air pollution sources that contribute the most to racial disparities. Their hope was that the information could help shape policy to reign in those sources of pollution.
