dc.description.abstract Particle size distribution patterns of trace elements and metals across three size fractions (<0.25 μm, quasi-ultrafine particles, q-UF; 0.25–2.5 μm, accumulation particles; 2.5–10 μm, coarse particles) were analysed in indoor and outdoor air at 39 primary schools across Barcelona (Spain). Special attention was paid to emission sources in each particle size range. Results evidenced the presence in q-UF particles of high proportions of elements typically found in coarse PM (Ca, Al, Fe, Mn or Na), as well as several potentially health-hazardous metals (Mn, Cu, Sn, V, Pb). Modal shifts (e.g., from accumulation to coarse or q-UF particles) were detected when particles infiltrated indoors, mainly for secondary inorganic aerosols. Our results indicate that the location of schools in heavily trafficked areas increases the abundance of q-UF particles, which infiltrate indoors quite effectively, and thus may impact children exposure to these health-hazardous particles.
dc.description.sponsorship The research leading to these results has received funding from the European Research Council under the ERC Grant Agreement number 268479 – the BREATHE project. Additional funding for specific instrumentation was provided by national project IMPACT (CGL 2011-26574), the Spanish Ministry of Agriculture, Food and the Environment (UCA 2009020083), and projects VAMOS (CLG 2010-19464-CLI) and GRACCIE CSD2007-00067. Support is acknowledged to Generalitat de Catalunya 2009 SGR8.
