Air Pollution Causes 200,000 Early US Deaths: Study

Posted by feww on August 29, 2013

Victims of air pollution typically die about a decade prematurely

Air pollution causes 200,000 early deaths in the U.S., according to a new MIT study, which also finds vehicle emissions as the biggest contributor to these premature deaths.

Researchers from MIT’s Laboratory for Aviation and the Environment have tracked ground-level emissions from multiple sources including vehicle tailpipes, industrial smokestacks, marine and rail operations, and commercial and residential heating throughout the United States, and found that the pollution causes about 200,000 early deaths each year.

Highlights from the report

  • Road transportation are the most significant contributor to air pollution, causing 53,000 premature deaths.
  • Power generation follows closely with 52,000 deaths
  • California air pollution commits about 21,000 people to early deaths annually,
  • The highest emissions-related mortality rate among 5,695 U.S. cities mapped was in Baltimore, where 130 out of every 100,000 residents likely die each year due to long-term exposure to air pollution.

“In the past five to 10 years, the evidence linking air-pollution exposure to risk of early death has really solidified and gained scientific and political traction,” says Steven Barrett, an assistant professor of aeronautics and astronautics at MIT. “There’s a realization that air pollution is a major problem in any city, and there’s a desire to do something about it.”

The researchers have published their results in the journal Atmospheric Environment.
