Abstract
Air pollution has been estimated to be one of the leading environmental health risks in Finland. National health impact estimates existing to date have focused on particles (PM) and ozone (O3). In this work, we quantify the impacts of particles, ozone, and nitrogen dioxide (NO2) in 2015, and analyze the related uncertainties. The exposures were estimated with a high spatial resolution chemical transport model, and adjusted to observed concentrations. We calculated the health impacts according to Word Health Organization (WHO) working group recommendations. According to our results, ambient air pollution caused a burden of 34,800 disability-adjusted life years (DALY). Fine particles were the main contributor (74%) to the disease burden, which is in line with the earlier studies. The attributable burden was dominated by mortality (32,900 years of life lost (YLL); 95%). Impacts differed between population age groups. The burden was clearly higher in the adult population over 30 years (98%), due to the dominant role of mortality impacts. Uncertainties due to the concentration–response functions were larger than those related to exposures.
La pollution atmosphérique a été estimée comme l'un des principaux risques environnementaux pour la santé en Finlande. Les estimations nationales d'impact sanitaire existant à ce jour se sont concentrées sur les particules (PM) et l'ozone (O3). Dans ce travail, nous quantifions les impacts des particules, de l'ozone et du dioxyde d'azote (NO2) en 2015, et analysons les incertitudes associées. Les expositions ont été estimées à l'aide d'un modèle de chimie-transport à haute résolution spatiale, puis ajustées aux concentrations observées. Nous avons calculé les impacts sanitaires conformément aux recommandations du groupe de travail de l'Organisation mondiale de la santé (OMS). D'après nos résultats, la pollution de l'air ambiant a engendré un fardeau de 34 800 années de vie ajustées sur l'incapacité (DALY). Les particules fines en constituaient le principal contributeur (74 %) au fardeau de morbidité, ce qui concorde avec les études antérieures. Le fardeau attribuable était dominé par la mortalité (32 900 années de vie perdues (YLL) ; 95 %). Les impacts différaient selon les groupes d'âge de la population. Le fardeau était nettement plus élevé au sein de la population adulte de plus de 30 ans (98 %), en raison du rôle prépondérant des impacts liés à la mortalité. Les incertitudes imputables aux fonctions concentration-réponse étaient supérieures à celles associées aux expositions.
