Volatile organic compounds and their contribution to ground-level ozone formation in a tropical urban environment.

This study aims to determine the trends of volatile organic compound (VOC) concentrations and their potential contribution to O formation. The hourly data (August 2017 to July 2018) for 29 VOCs were obtained from three Malaysian Department of Environment continuous air quality monitoring stations with different urban backgrounds (Shah Alam, Cheras, Seremban). The Ozone Formation Potential (OFP) was calculated based on the individual Maximum Incremental Reactivity (MIR) and VOC concentrations.
