EPA Finds Black Americans Face More Health-Threatening Air Pollution
Black Americans are subjected to higher levels of air pollution than white Americans regardless of their wealth, researchers with the U.S. Environmental Protection Agency conclude. Researchers at the EPA's National Center for Environmental Assessment looked at facilities emitting air pollution, as well as at the racial and economic profiles of surrounding communities. They found that black Americans were exposed to significantly more of the small pollution particles known as PM 2.5, which have been associated with lung disease, heart disease, and premature death. Most such sooty pollution comes from burning fossil fuels. Blacks were exposed to 1.54 times more of this form of pollution—particles no larger than 2.5 microns, that lodge in lung tissue—than the population at large. Poor people were exposed to 1.35 times more, and all non-whites to 1.28 times more, according to the study, published in the American Journal of Public Health.
