    Anthropogenic and Biogenic Volatile Organic Compounds and Ozone Formation Potential in Ambient Air of Kuala Lumpur, Malaysia
    (IOP Publishing, 2019) H H A Hamid; M H M Hazman; M S M Nadzir; R Uning; M T Latif; N Kannan
    The measurement of anthropogenic and biogenic volatile organic compounds (VOCs) in urban air is important because of their toxic effects and because they can produce secondary air pollutants (e.g. ozone, particulate matter). Benzene, toluene, ethylbenzene and xylenes (BTEX), representing anthropogenic VOCs (AVOCs), and isoprene, a biogenic VOC (BVOC), were monitored at an urban site in Kuala Lumpur (KL). Active sampling was conducted using sorbent tubes packed with Tenax®TA/1 TD for 5 days (daytime). Analysis of VOCs was performed using Thermal Desorption-Gas Chromatography Mass Spectrometry (TD-GCMS).
