| Surfactant is one of the pollutants derived from atmospheric aerosol that can adversely affect the human health and environment. This study aims to characterize the level of anionic surfactants as Methylene Blue Active Substances (MBAS) and Linear Alkylbenzene Sulphonates (LAS) extracted from atmospheric aerosol from urban (Kuala Lumpur) and suburban (Bangi) area of Malaysia. For aerosol sampling, a high volume sampler (HVAS) with a cascade impactor was used to collect atmospheric aerosol sample according to particle size (coarse mode (>1.5 �m) and fine mode ( 0.05). From this study, it can be concluded that MBAS concentrations in urban and suburban atmosphere are not fully affected by commercial LAS. Majority of MBAS may be presented from other natural activities and anthropogenic sources such as motor vehicle emission, combustion of biomass, and the earth's crust. The management of surfactants? use needs to be reconsidered to enhance a better atmosphere especially in urban and suburban area in the future. ?2021 by authors, all rights reserved. |
