Characterisation and source identification of PM10 aerosol samples collected with a high volume cascade impactor in Brisbane (Australia).

PM10 (particulate matter with aerodynamic diameter 2.7-μm size fraction, with the 1.3-μm aerosols. The aerosol mass and concentrations of chemical components related to human activities show a bimodal size-distribution pattern, with most of the mass in the accumulation range ( 2.7-μm fractions, while the organics and vehicular exhausts factors explain almost all the aerosol mass in the <0.61-μm fractions.
