Chemical characterization and source apportionment of PM2. 5 near semi-urban residential-industrial areas. Exposure and Health, 14(1), 149-170.https://repoemc.ukm.my/handle/123456789/503This study aims to determine the concentrations of the trace metals (TM) and water soluble inorganic ions (WSII) of the PM2.5 pollutant collected in the suburban industrial-residential airshed during the southwest (SW), inter-monsoon (IM) and northeast (NE) monsoons in Skudai, Johor Bahru. The PM2.5 samples were collected using the MiniVol™ portable air sampler equipped with filter paper. The TM and WSII of PM2.5 were determined by using the inductively coupled plasma-mass spectrometry (ICP-MS) and ion chromatography (IC), respectively. The sources of the PM2.5 composition were determined using the Positive Matrix factorisation (PMF) and the origin of the measured air-masses were determined by the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT).enPM2.5Chemical characterizationSource apportionmentPMFTrace metalsInorganic ionsJournal
