| Abstract | Particulate matter has many negative effects to human health, natural environment, and atmosphere. In Bangkok, the 24 hours particulate matter with the diameter size of not more than 2.5 micrometers (PM2.5) concentration exceeded the ambient air quality standard (50 micrograms per cubic meter), and it was one of the main pollution problems in Thailand that must be resolved according to the National Agenda for PM2.5 management in Thailand in 2018. This research study was done to assess the effects of policy of on-road mobile sources in Bangkok Metropolitan Region (BMR) using the Weather Forecast Research Model (WRF) version 4.2 and the Comprehensive Air Quality Model with Extension (CAMx) version 7.0. Emission Inventory in this study was updated form the previous studies to the base year of 2018 for three sectors, including on-road, crop residue open burning and biogenic emission. The result of the maximum monthly average PM2.5 showed that 49.83 μg/m3 would happen in January as compared with 31.97 μg/m3 in August. The hourly maximum concentrations were 443 μg/m3 and 173 μg/m3 , respectively. The emission reduction policies on-road mobile sources assuming that the diesel vehicles in BMR were switched to Euro 6 engine standards. The results of PM2.5 maximum monthly average PM2.5 was about 46 μg/m3 in January while, in August, it was 29 μg/m3 . When compared with a base case, the concentration of PM2.5 was reduced by 2-3 μg/m3 . Further studies should redefine the selection scheme of the WRF model to obtain better results. In addition, ambient PM2.5 reduction assessments should be undertaken in other sources to determine the impact of all short- and long-term policies in the National Agenda for PM2.5 management in Thailand. |
