| Abstract | Particulate matters and ground-level ozone are serious atmospheric pollutants having strong association with adverseeffects onhuman health, ecosystem and climate. Thailand Pollution Control Department (PCD) reported the exceedance of NAAQS of both PM2.5and PM10measured in ambient air of Bangkok Metropolitan Region (BMR). This research focusedon assessing PM and O3levelsin BMR using WRF (Weather Forecast Research Model) –CAMx(Comprehensive Air Quality Model with Extension) modeling system for 2016. The modeled results of fine particles (PM2.5) were used toestimate the health burden caused by the pollutant in BMR. WRF (version 3.7) performance was evaluated using the hourlyground observationsat Don Muang and Suvarnabhumi Airports(for wind speed(WS), wind direction(WD), temperature(To), relative humidity(RH))which show satisfactory for Toand RH and moderation for WS and WD. Emission input data for CAMx were preparedfortwo main source sectorsfor 2016, on-road transport and VOC emission from biogenic sources, while for other sources, i.e. biomass open burning, industrial, power plant, livestock, farm machine, aviation, and residential combustion, the available emission data for 2015 were used. Biogenic VOC emissions were calculated using GLOBEIS model using the landuse of the domain. The transport emissions from BMR were calculated using the 2016 fleet data. The 24h-average modeled PM2.5, PM10of the year 2016, and hourly ozone were extracted from CAMx outputs and compared to theobserved datafor the model performanceevaluation.The simulated 24h PM2.5and PM10in an ambient site in Bangkok were in the range of 8 –82 μg/m3 and 8 –92 μg/m3, respectively, higher in dry season (11-92 μg/m3)and lower in wetseason (8 –40 μg/m3). The weekly average modeled PM2.5(11 -48 μg/m3) and its composition (elementary carbon -EC, organic carbon -OC, sulfateparticles -PSO4, and nitrateparticles -PNO3) were compared to observed data from a research project on “A Study on Urban Air Pollution Improvement in Asia” collaborated by AIT and JICA. The results showed moderate satisfactory for hourly PM, and betteragreement for daily PM and weekly PM2.5in term of statistical evaluation.The simulatedPM2.5were used to estimate health burden in BMR by using BenMAP-CE. The results indicated that PM2.5-related mortalities account for 6.0%, 20.4% and 13.0% of total deaths by all causes, ischemic heart disease, and lung cancerin BMR.Further studies should analyze emission reduction scenarios and effects on human health in BMR to provide input to policy making. |
