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: intensified urban development (S1), increased agricultural land (S2), and expansion of urban parks (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.<\/p>\n

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.<\/p>\n

These findings highlight the intricate relationship between land use change, 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

Onades de calor amplifiquen la contaminaci\u00f3 de l\u2019aire, incrementant 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 examina 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: intensificaci\u00f3 del desenvolupament urb\u00e0 (S1), augment de les terres agr\u00edcoles (S2) i expansi\u00f3 de parcs urbans (S3). Mitjan\u00e7ant una modelitzaci\u00f3 de la qualitat de l\u2019aire d\u2019alta resoluci\u00f3, s\u2019ha aplicat una avaluaci\u00f3 quantitativa de l\u2019impacte sobre la salut per analitzar els canvis en les concentracions de contaminants atmosf\u00e8rics (NO2, O3, PM2.5, PM10), la mortalitat atribu\u00efble i el compliment dels est\u00e0ndards de qualitat de l\u2019aire de l\u2019OMS.<\/p>\n

Els resultats mostren que, mentre que la mortalitat associada al NO2 i al PM va disminuir lleugerament en els escenaris agr\u00edcoles (S2) i de parcs (S3), la mortalitat atribu\u00efble a l\u2019oz\u00f3 va mostrar un patr\u00f3 complex i no lineal. L\u2019escenari d\u2019expansi\u00f3 urbana (S1) va conduir a menys defuncions relacionades amb l\u2019oz\u00f3 malgrat un augment marginal de les concentracions d\u2019O3. El compliment de les directrius de l\u2019OMS es va mantenir constant per al NO2 i el PM, per\u00f2 els nivells d\u2019oz\u00f3 van superar els l\u00edmits recomanats en tots els escenaris. Les an\u00e0lisis espacials van identificar cl\u00fasters heterogenis de mortalitat relacionada amb la contaminaci\u00f3, condicionats per les variacions de temperatura i els patrons locals d\u2019\u00fas del s\u00f2l.<\/p>\n

Aquests resultats destaquen la relaci\u00f3 complexa entre el canvi d\u2019\u00fas del s\u00f2l, la qualitat de l\u2019aire i la salut p\u00fablica, i posen \u00e8mfasi en la necessitat d\u2019estrat\u00e8gies integrades de planificaci\u00f3 urbana que tinguin en compte tant les respostes espec\u00edfiques de cada contaminant com les condicions meteorol\u00f2giques. Les investigacions futures haurien d\u2019incorporar funcions d\u2019exposici\u00f3-resposta en temps real i modelitzacions urbanes d\u2019alta resoluci\u00f3 per millorar les avaluacions d\u2019impacte en la salut i orientar pol\u00edtiques de desenvolupament urb\u00e0 sostenible.<\/p>\n
