| Abstract | 24-h sampling was conducted to collect coarse and fine particulate matter by Dichotomous samplers during March - May 2002 at three sampling sites in Bangkok Metropolitan Region. The samples were analyzed for mass concentrations, 7 ionic species (IC, this study), 20 elements (Proton-induced X-ray emission, NERI, Denmark) and Elemental carbon (Reflectometer, AIT and Goteborg, Sweden). The data for Bang Na were analyzed by receptor modeling called Positive Matrix Factorization (PMF) to identify the sources contribution to respirable suspended particulates in the study area. A few cases at each site, the 24-h average PM10 concentration were exceeding the Thailand's Ambient Air Quality Standards and PM2.5 concentration were exceeding US National Ambient Air Quality Standard. 55-60 % by weight of PM10 in Bangkok are PM2.5. For coarse particulate matter, four sources were identified: 1) soil and road dust characterized by high concentrations of Calcium (Ca), Silicon (Si), Aluminum (Al), and Iron (Fe); 2) Sea-salts with high concentrations of Sodium (Na+) and Chlorine (Cl); 3) Metal industry dominated by Zinc (Zn), Iron (Fe) and Manganese (Mn); and 4) Motor vehicle with high concentrations of Bromine (Br) and Manganese (Mn). The relative contributions of these sources are 70%, 28%, 1 % and 1 %, respectively. For fine particulate matter, six sources were identified, that are: 1) Industry and biomass burning with high Potassium (K), Sulfur (S) and Sulphate (SO/-); 2) motor vehicle characterized by high Elemental Carbon (EC) and Zinc (Zn); 3) secondary pollutant has high Sulphate (SO/); 4) sea salts dominated by Sodium (Na+) and Magnesium (Mg 2 +), 5) soil and road has high Silicon (Si), Aluminum (Al), Iron (Fe) and Calcium (Ca);; and 6) metal industry has high Fe, Zn, Lead (Pb) and Nitrate (N03} The relative contributions of these sources are 43%, 42%, 6%, 4%, 3% and 2%, respectively. |
