(author)Road dust emission is an emerging issue in air quality due to the lack of remediation measures in contrast to vehicle exhaust emissions. The evidence of receptor modeling studies allows for quantifying impact on a few receptors, but the high cost of PM chemical speciation data and the questionable representativeness of single monitoring sites,...article 2016

(author), Peñuelas, J. (author), Mohr, C. (author), Prévôt, A.S.H. (author), Querol, X. (author)Mean annual biomass burning contributions to the bulk particulate matter (PM X) load were quantified in a southern-European urban environment (Barcelona, Spain) with special attention to typical Mediterranean winter and summer conditions. In spite of the complexity of the local air pollution cocktail and the expected low contribution of biomass...article 2012

Otjes, R.P. (author), Blom, M.J. (author), Pandolfi, M. (author), Amato, F. (author), Reche, C. (author), Alastuey, A. (author), Querol, X. (author)Abstract. Real-time measurements of ambient concentrations of gas-phase ammonia (NH3) were performed in Barcelona (NE Spain) in summer between May and September 2011. Two measurement sites were selected: one in an urban background traffic-influenced area (UB) and the other in the historical city centre (CC). Levels of NH3 were higher at CC (5.6...article 2012

(author), Querol, X. (author)Urban aerosol samples collected in Barcelona between 2008 and 2009 were toxicologically characterised by means of two complementary methodologies allowing evaluation of their Reactive Oxidative Stress (ROS)-generating capacity: the plasmid scission assay (PSA) and the dichlorodihydrofluorescin assay (DCFH). The PSA determined the PM dose able to...article 2012
