Fine particulate matter PM_2.5 and PM₁₀ at heavy traffic areas in Bangkok: Application of the air pollution model (TAPM)

Air particulate matter was measured at two heavily congested roads in Bangkok during the dry season in 2006. Air samples of both coarse particulate matter (PM₁₀) and fine particulate matter (PM_2.5) were collected by individual, low-flow personal air samplers. The numerical simulations of the PM₁₀ concentration were made by the Air Pollution Model (TAPM, version 3.0). An emissions inventory for PM₁₀ was developed based on the local traffic records near the stations. To improve the level of accuracy in future simulations of urban air quality, it is necessary to implement PM₁₀ and PM_2.5 emission inventories for Bangkok. The Air Pollution Model (TAPM) could be applied under subtropical condition like Bangkok. However, to improve its accuracy, some parameters such as urban heat island, subtropical boundary layer and urban canopy should be included in the model. This is an abstract of a paper presented at the 14th International Union of Air pollution Prevention and Environmental Protection Associations World Congress 2007 (Brisbane, Queensland 9/9-13/2007).
