| Abstract | In this study particulate samples were collected at three sites, Bang Na, Bangkok University and AIT in Bangkok Metropolitan Region (BMR) during rainy season (10 June - 30 August 2003). Two collocated dichotomous samplers were used to collect 24-hour PM2.s and PM10.2.s on mixed cellulose ester and Quartz fiber filters. 52 pairs of Quartz fiber and mixed cellulose ester samples were collected from three sampling sites. The mass concentration and chemical component of fine (PM2.s) and coarse (PM10-2.s) fraction were determined. Mixed cellulose samples evaluated for mass measurements and analyzed for elements by proton-induced X-ray emission (PIXE) and black carbon by reflectometer. Quartz samples were analyzed for ionic compositions by ion chromatography (IC). None of the 24-h average concentrations of PM10 exceeded the Thailand's Ambient Air Quality Standards and all PM2.s concentration below the US National Ambient Air Quality Standard. The highest average concentration of PM2.s and PM10 were found at Bang Na. AIT had the lowest average concentration of PM2.s and PM10. Calcium (Ca2+), Sodium (Na+), Chloride (Cl") and Nitrate (N03.) were the major components in coarse fraction, while Ammonium (N!Li ), Potassium (K+) and Sulphate (So/·) were major components in the fine fraction at all sites. Furthermore the elemental carbon was dominating in PM2.5 and crustal elements were predominant species in PM10.2.s. Chemical Mass Balance model (CMB) and Constrained Physical Receptor model (COPREM) are the receptor models used to determine the particulate source contribution. The results of both models showed that the major contributions of fine fraction at all sites were traffic, biomass and secondary sulfate. For the coarse fraction, construction, soil, N03·, and sea salts were the major sources. |
