Concentration and source apportionment of volatile organic compounds (VOCs) in the ambient air of Kuala Lumpur, Malaysia. Natural Hazards, 85, 437-452.https://repoemc.ukm.my/handle/123456789/605The accumulation of volatile organic compounds (VOCs) in ambient air affects air quality through the generation of surface level ozone and secondary organic aerosol. A study of the distribution and source apportionment of VOCs was conducted at two stations to investigate the air quality status of Kuala Lumpur. Samples of ambient air were collected into Tedlar sampling bags using an air sampling pump and then pre-concentrated with solid-phase micro-extraction fibre. Gas chromatography-mass spectrometry (GC-MS) was employed to measure the VOC species.enVOCsBTEXSource apportionmentCongested areasResidential-urban environmentJournal
