Impact of short-term exposure to air pollution on natural mortality and vulnerable populations: a multi-city case-crossover analysis in Belgium

Abstract Background The adverse effect of air pollution on mortality is well documented worldwide but the identification of more vulnerable populations at higher risk of death is still limited. The aim of this study was to evaluate the association between natural mortality (overall and cause-specific) and short-term exposure to five air pollutants (PM 2.5 , PM 10 , NO 2 , O 3 and black carbon) and identify potential vulnerable populations in Belgium. Methods We used a time-stratified case-crossover design with conditional logistic regressions to assess the relationship between mortality and ai... Mehr ...
