|Abstract: ||Under the ANSTO Aerosol Sampling Program (ASP), PM2.5 samples were collected at seven sites in NSW, Australia, since 1998. The elemental composition of each sample was determined using IBA techniques, after which positive matrix factorisation (PMF) analysis was carried out to obtain a set of source fingerprints and their concentrations for each of the sites.
Spatial interpolation of elemental concentrations as well as PMF source fingerprints was carried out using the kriging interpolation technique. The spatial concentration maps generated provided an indication of which regions received higher PM2.5 concentrations, which also varied with season. For example higher concentrations of BC and K occurred in winter, whereas, in summer the concentrations of sea salt were higher. The two inland sites, Richmond and Muswellbrook, received the least salt, although, there were sampling days on which higher concentrations of salt were measured at the inland site than the coastal site, indicating sources of salt other than the ocean.|
