fractions of particulate matter (PM) in multiple locations, especially in Europe. Objectives: We
estimated the short-term effects of PM with aerodynamic diameter≤ 10 μm (PM10),≤ 2.5 μm
(PM2. 5), and between 2.5 and 10 μm (PM2. 5–10) on all-cause, cardiovascular, and
respiratory mortality in 10 European Mediterranean metropolitan areas within the MED-
PARTICLES project. Methods: We analyzed data from each city using Poisson regression …
