AbstractAbstract
[en] During October 1995 - January 1996, 66 samples of airborne particulate matter were collected from Bangkok and Samutprakan provinces. Samples of the particle sizes of 2.5 - 10 microns (33 samples) and less than 2.5 microns (33 samples) were determined for elemental concentration of 34 elements. A comparative study of the data from both sampling size was initiated to investigate the trends, source and origin of the aerosols by comparing the concentration, enrichment factor (E F) and coarse/ fine ratio. The results show Al, Fe, Sc are from crustal elements, Ca, K, Mn, V has moderate high E F and As, Br, Cd, Cu, Ni, Sb, Se and Zn has rather high E F. Comparison between the two sites yields higher levels of As and Sb at Samutprakan appearly due to smelting or other industries nearby. Higher level of Br might be due to the heavier of transportation of trucks in and out of the city
