10-year study shows how air pollution fosters heart disease; accelerated plaque build-up in arteries

Green Car Congress

Long-term exposure to particulate air pollution has been linked to an increased risk of heart disease, but the biological process has not been understood. Participant-specific pollutant concentrations averaged over the years 2000–10 ranged from 9.2–22.6 The study is published in The Lancet. and NO x between 1999 and 2012. μg PM 2.5 /m
