TY - JOUR ID - 1159387 AU - Čupr, Pavel - Flegrová, Zuzana - Franců, Juraj - Landlová, Linda - Klánová, Jana PY - 2013 TI - Mineralogical, chemical and toxicological characterization of urban air particles JF - Environment International VL - 54 IS - 2013 SP - 26-34 EP - 26-34 PB - PERGAMON-ELSEVIER SCIENCE LTD SN - 01604120 KW - Atmospheric particles KW - Cascade impactor KW - Bound chemicals KW - PAHs KW - Genotoxicity KW - Morphological and mineralogical analysis N2 - Systematic characterization of morphological, mineralogical, chemical and toxicological properties of various size fractions of the atmospheric particulate matter was a main focus of this study together with an assessment of the human health risks they pose. Even though near-ground atmospheric aerosols have been a subject of intensive research in recent years, data integrating chemical composition of particles and health risks are still scarce and the particle size aspect has not been properly addressed yet. Filling this gap, however, is necessary for reliable risk assessment. A high volume ambient air sampler equipped with a multi-stage cascade impactor was used for size specific particle collection, and all 6 fractions were a subject of detailed characterization of chemical (PAHs) and mineralogical composition of the particles, their mass size distribution and genotoxic potential of organic extracts. Finally, the risk level for inhalation exposure associated to the carcinogenic character of the studied PAHs has been assessed. The finest fraction (<0.45 mu m) exhibited the highest mass, highest active surface, highest amount of associated PAHs and also highest direct and indirect genotoxic potentials in our model air sample. Risk assessment of inhalation scenario indicates the significant cancer risk values in PM 1.5 size fraction. This presented new approach proved to be a useful tool for human health risk assessment in the areas with significant levels of air dust concentration. ER -
