Heatwaves amplify air pollution, increasing public health risks, particularly in urban areas where land use influences the distribution of pollutants. This study examines the short-term health effects of air pollution during a two-week heatwave in the Barcelona Metropolitan Area under different land use scenarios: expansion of urban parks (S1), increased agricultural land (S2), and intensified urban development (S3). Using high-resolution air quality modelling we applied a quantitative health impact assessment to analyse the changes in air pollutant concentrations (NO2, O3, PM2.5, PM10), their attributable mortality and compliance with WHO air quality standards.The results show that while NO2 and PM-related mortality decreased slightly in the agriculture (S2) and parks scenarios (S3), ozone-attributable mortality displayed a complex, non-linear pattern. The urban expansion (S1) scenario led to fewer ozone-related deaths despite a marginal rise in O3 concentrations. Compliance with WHO guidelines remained consistent for NO2 and PM, but ozone levels exceeded recommended limits in all scenarios. Spatial analyses identified heterogeneous clusters of pollution-related mortality, shaped by temperature variations and local land use patterns.These findings highlight the intricate relationship between land use changes, air quality, and public health, emphasizing the need for integrated urban planning strategies that consider both pollutant-specific responses and meteorological conditions. Future research should incorporate real-time exposure response functions and high-resolution urban modelling to improve health impact assessments and inform sustainable urban development policies.<\/p>\n

Les onades de calor amplifiquen la contaminaci\u00f3 de l\u2019aire, augmentant els riscos per a la salut p\u00fablica, especialment en zones urbanes on l\u2019\u00fas del s\u00f2l influeix en la distribuci\u00f3 dels contaminants. Aquest estudi analitza els efectes a curt termini de la contaminaci\u00f3 atmosf\u00e8rica durant una onada de calor de dues setmanes a l\u2019\u00c0rea Metropolitana de Barcelona sota diferents escenaris d\u2019\u00fas del s\u00f2l: expansi\u00f3 de parcs urbans (S1), increment de s\u00f2l agr\u00edcola (S2) i intensificaci\u00f3 del desenvolupament urb\u00e0 (S3). Mitjan\u00e7ant una modelitzaci\u00f3 de qualitat de l\u2019aire d\u2019alta resoluci\u00f3, es va aplicar una avaluaci\u00f3 quantitativa de l\u2019impacte en salut per analitzar els canvis en les concentracions de contaminants atmosf\u00e8rics (NO\u2082, O\u2083, PM\u2082.\u2085, PM\u2081\u2080), la mortalitat atribu\u00efble i el compliment dels est\u00e0ndards de qualitat de l\u2019aire de l\u2019OMS. Els resultats mostren que, tot i que la mortalitat atribu\u00efble al NO\u2082 i a les part\u00edcules (PM) va disminuir lleugerament en els escenaris agr\u00edcola (S2) i de parcs (S3), la mortalitat relacionada amb l\u2019oz\u00f3 (O\u2083) va presentar un patr\u00f3 complex i no lineal. L\u2019escenari d\u2019expansi\u00f3 urbana (S1) va comportar menys morts associades a l\u2019oz\u00f3, malgrat un lleuger augment de les concentracions d\u2019aquest contaminant. El compliment de les directrius de l\u2019OMS es va mantenir estable per al NO\u2082 i les part\u00edcules, per\u00f2 els nivells d\u2019oz\u00f3 van superar els l\u00edmits recomanats en tots els escenaris. Les an\u00e0lisis espacials van identificar agrupacions heterog\u00e8nies de mortalitat relacionada amb la contaminaci\u00f3, modelades per les variacions de temperatura i els patrons d\u2019\u00fas del s\u00f2l a escala local. Aquests resultats posen de manifest la relaci\u00f3 complexa entre els canvis en l\u2019\u00fas del s\u00f2l, la qualitat de l\u2019aire i la salut p\u00fablica, i subratllen la necessitat d\u2019estrat\u00e8gies integrades de planificaci\u00f3 urbana que tinguin en compte tant les respostes espec\u00edfiques a cada contaminant com les condicions meteorol\u00f2giques. Les futures investigacions haurien d\u2019incorporar funcions de resposta a l\u2019exposici\u00f3 en temps real i models urbans d\u2019alta resoluci\u00f3 per millorar les avaluacions d\u2019impacte en salut i informar pol\u00edtiques de desenvolupament urb\u00e0 sostenible.<\/p>\n
