Ambient particulate air pollution and daily mortality in 652 cities

New England Journal of Medicine Aug 29, 2019

Liu C, Chen R, Sera F, et al. - Researchers assessed the correlations of inhalable particulate matter (PM) with an aerodynamic diameter of ≤ 10 μm (PM10) and fine PM with an aerodynamic diameter of ≤ 2.5 μm (PM2.5) with daily all-cause, cardiovascular, and respiratory mortality across multiple countries or regions. On average, an elevation of 10 μg per cubic meter in the 2-day moving average of PM10 concentration, which represents the average over the current and previous day, was related to rises of 0.44%, 0.36%, and 0.47% in daily all-cause mortality, daily cardiovascular mortality, and daily respiratory mortality, respectively. For the same change in PM2.5 concentration, the corresponding rises in daily mortality were 0.68%, 0.55%, and 0.74%. These correlations remained important following adjustment for gaseous pollutants. In places with lower annual mean PM concentrations and higher annual mean temperatures, a consistent rise in daily mortality with rising PM concentration was exhibited by the pooled concentration-response curves, with steeper slopes at lower PM concentrations associations were stronger. Overall, in > 600 cities across the globe, independent relations between short-term exposure to PM10 and PM2.5 and daily all-cause, cardiovascular, and respiratory mortality were demonstrated. These data strengthen the evidence of a connection between mortality and PM concentration built in the regional and local studies.
