2024 No Variability in exposure to ambient ultrafine particles in urban schools: Comparative assessment between Australia and Spain https://pubmed.ncbi.nlm.nih.gov/26760710/ Mazaheri, Mandana Multiple Countries Experimental Observational Exposure Temperature Humidity Nitrogen Dioxide (NO2) Ambient particles Exposure New particle formation Urban environmental High isolation areas Ultrafine particle exposures were compared in schools across Brisbane and Barcelona. Traffic dominated exposure in Barcelona; mid-day new particle formation was key in Brisbane. Patterns varied by land use and climate, guiding city-specific mitigation. 2016
