Item Embargo Biomass burning as the main source of organic aerosol particulate matter in Malaysia during haze episodes(Elsevier, 2004) M. Radzi bin Abas; Daniel R. Oros; B.R.T. SimoneitThe haze episodes that occurred in Malaysia in September-October 1991, August-October 1994 and September-October 1997 have been attributed to suspended smoke particulate matter from biomass burning in southern Sumatra and Kalimantan, Indonesia. In the present study, polar organic compounds in aerosol particulate matter from Malaysia are converted to their trimethylsilyl derivatives and analyzed by gas chromatography-mass spectrometry in order to better assess the contribution of the biomass burning component during the haze episodes.Item Embargo Organic composition of aerosol particulate matter during a haze episode in Kuala Lumpur, Malaysia(Elsevier, 2004) M. Radzi Bin Abas; Noorsaadah A. Rahman; Nasr Yousef M.J. Omar; M. Jamil Maah; Azizan Abu Samah; Daniel R. Oros; Angelika Otto; Bernd R.T. SimoneitcThe solvent-extractable compounds of urban airborne particulate matter were analyzed to determine the distributions of homologous and biomarker tracers. Samples were collected by high-volume air filtration during the haze episode of 1997 around the University of Malaya campus near Petaling Jaya, a suburb of Kuala Lumpur, Malaysia.
