After decades of studies demonstrating that poor people and minorities are more likely than their white counterparts to live near health hazards such as toxic waste sites, landfills and congested highways, a new study in the journal PLOS One took a more refined look at a particular aspect in the area of “environmental injustice”: exposure to nitrogen dioxide. The pollutant—which is produced by cars, construction equipment and industrial sources—is linked to higher risk of both asthma and heart attack.
Using data from the 2000 Census, researchers determined that minorities are on average exposed to 38 percent higher levels of outdoor nitrogen dioxide. The gap varies depending where in the country they live, with the upper Midwest and the Northeast seeing the greatest disparities, as well as major cities. All told the disparity accounts for an additional 7,000 deaths due to heart disease annually.
"The biggest finding is that we have this national picture of environmental injustice and how it varies by state and by city," said Julian Marshall, a professor of environmental engineering at the University of Minnesota and one of the authors of the study, according to The Washington Post. "The levels of disparity that we see here are large and likely have health implications."
There are a number of possibilities to account for the disparities. For example, according to The Post, many “urban highways...were originally routed through minority communities that were politically easier to uproot than middle-class white neighborhoods” and “highways and landfills also depress nearby property values, meaning that people who can afford to live elsewhere do, while those who can't remain within their influence.”
