This is perhaps the first time that research has quantified the racial gap between who causes air pollution - and who ends up breathing it.
To some, this news might come across as funny and even unbelievable - given the racial dialogues that are populating the public sphere. The air that the Americans are breathing is not equal.
According to a recently conducted study, Blacks and Hispanics end up disproportionately breathing in the air that is polluted by the non-Hispanic whites.
This is perhaps the first time that research has quantified the racial gap between who causes air pollution - and who ends up breathing it. "Pollution is disproportionately caused by whites, but disproportionately inhaled by black and Hispanic minorities," the study said.
USA Today reports that poor air quality still continues to be the largest environmental health risk in the United States. The study also warns of the same problem. There is a staggering revelation that with 100,000 deaths per year, more Americans die from air pollution than car crashes and murders combined.
Even then, not everyone is equally exposed to poor air quality, and at the same time, nor are all the people equally responsible for generating it. This comes at a time when people thought that things could not get worse in the debate of racial disparity in the nation. Not to mention that it would naturally beg the question is the racism so high that even the air becomes unequal? (Food for thought).
“Even though minorities are contributing less to the overall problem of air pollution, they are affected by it more,” said study co-author Jason Hill, an engineering professor at the University of Minnesota, who is white. “Is it fair (that) I create more pollution and somebody else is disproportionately affected by it?”
Hill said that while the air in the U.S. has gotten cleaner in the past decade, pollution inequity has remained stubbornly high.
"What is especially surprising is just how large pollution inequity is and has been for well over a decade," Hill said.
The study, led by the University of Washington and the University of Minnesota, analyzed the type of pollution that is known as "PM 2.5" – tiny grains of "particulate matter" that are especially dangerous to human health because they can get deep into our lungs.
Those particles, at 2.5 micrometers far smaller than the width of a human hair, are produced by car tailpipes, power plant smokestacks and burning materials.
“Similar to previous studies, we show that racial-ethnic minorities are exposed to more pollution on average than non-Hispanic whites,” said first author Christopher Tessum, a research scientist in the UW’s civil and environmental engineering department and a recent University of Minnesota graduate.
“What is new is that we find that those differences do not occur because minorities on average cause more pollution than whites — in fact, the opposite is true.”
The study found that black and Hispanic Americans bear a "pollution burden:" Blacks are exposed to about 56 percent more pollution than what is caused by their consumption. For Hispanics, it is slightly higher – 63 percent.
However, USAToday reports that non-Hispanic whites experience a "pollution advantage," meaning they breathe about 17 percent less air pollution than whites cause.
The formula scientists used in their study is driven by disparities in amount of goods and services that groups consume and in the exposure to the resulting pollution. “On average, whites tend to consume more than minorities. It’s because of wealth,” Hill said.
USAToday cites the example of how the scientists found that whites spend more money on pollution-intensive goods and services than blacks and Hispanics, which means they generate more pollution than the other groups do.
“Someone had to make the pen you bought at the store,” the study's co-author Julian Marshall, an engineering professor at the University of Washington told USAToday. “We wanted to look at where the pollution associated with making that pen is located. Is it close to where people live? And who lives there?”
For this study, the category "non-Hispanic whites" also includes Asian-Americans and Native Americans. This is based on the source that the researchers used: government data on personal expenditures from the U.S. Bureau of Labor Statistics.

Other experts agreed with the research: “These findings confirm what most grassroots environmental justice leaders have known for decades, ‘whites are dumping their pollution on poor people and people of color,’” said Texas Southern University public affairs professor Robert Bullard, who was not part of the research. Bullard, often called the father of environmental justice, is African-American.
Researchers say their pollution inequity formula could be used on other types of environmental burdens. "The approach we establish in this study could be extended to other pollutants, locations and groupings of people," Marshall said. "When it comes to determining who causes air pollution – and who breathes that pollution – this research is just the beginning."
The study was published on Monday in the peer-reviewed journal Proceedings of the National Academy of Sciences.
