Recent Research Linking Heart and Lung Disease to Air Pollution

Long-term air pollution exposure and cardio- respiratory mortality: a review(32 page pdf, Gerard Hoek, Ranjini M Krishnan, Rob Beelen, Annette Peters, Bart Ostro, Bert Brunekreef, Joel D Kaufman, Environmental Health, May 28, 2013)

Today we summarize a literature review that assessed evidence for the link between air pollution and deaths from lung or heart disease, in light of developments over the last decade in terms of the knowledge  gained and the greater geographical data set including, specifically, China and Japan. Also the traditional and to some extent successful response to vehicle emissions over the last few decades was to reduce tailpipe emissions, leading this review to look more closely at non tailpipe emissions such as brake lining wear and emissions or particulates from the oil crankcase and tires. Results indicate that for every increase of 10 μg/m3 increase in PM2.5 exposure, there is an additional health risk of 6%.

  1. PM2.5 is categorized as either primary or secondary. Primary PM2.5 is emitted directly as a particle and enters the atmosphere as soot from roadways or tailpipe emissions. Secondary particulates form when precursor emissions react in the atmosphere and combine to create PM2.5. Twenty-five percent of Utah’s PM2.5 is considered primary, with the majority (seventy-five percent) is considered secondary, or the product of chemical reactions. Both categories of PM2.5 are the products of fuel combustion.

  2. According to a poll by the American Lung Association, Americans support improved standards for gasoline and tailpipe emissions from new vehicles by a 2-to-1 margin – 62 percent to 32 percent.

  3. This study illustrated the profound adverse effect tailpipe emissions can have on coronary perfusion in susceptible individuals.
