Characterisation of soluble Inorganic PM10 aerosols in Brisbane

Kumar, A. U. Wathsala, Bofinger, Neville, & Ayoko, Godwin A. (2007) Characterisation of soluble Inorganic PM10 aerosols in Brisbane. In 14th International IUAPPA World Congress, September 2007, Brisbane, Australia.


PM10 samples were collected from three sites in Brisbane over a period of 20 months. These samples were analysed for water soluble ionic species (Na+, K+, Mg2+, Ca2+, NH4+, Cl-,NO3-, SO42-, F-, Br-, NO2-, PO4-3) using Inductively coupled plasma optical emission spectrometer (ICP_OES )and Ion exchange chromatography (IC). Metallic species (Zn, Cu, Pb, Fe, Mn, Al) that are soluble in acid were also analysed using ICP-OES. Na+ and Cl- concentrations were high in all samples. Principal Components Analysis (PCA) was used to identify seasonal differences and weekend/weekday trends of the sample concentrations. This showed that seasonal variation played a major role in the soluble aerosol concentrations of the samples. PCA was also used to identify the sources of the samples and it could be concluded that sea salt is the major source of these aerosol samples.

Search Google Scholar™

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
