Sc.) - Asian Institute of Technology, 1988  aFor assessing acid deposition problem in Bangkok.  measurement of precipitation pH were made from October to  December 1987 at nine sampling stations. The measured pH of  rainfall ranged from 4.8 to 7.3. Particulate were also  collected at the same sampling stations during December 1987  to January 1988 for determining acidity and sulfate. The  concentration of sulfate in the atmosphere was relatively high  (from 26.0 to 48.0 ~g/m3). comparing with the value of Dorset.  Ontario. Canada and high concentration of particulate sulfate  was found near the roadside. But the acidity in particulates  was in the normal range (from 5.2 to 9.4 pg/m3). Emission of  S02 and NO. of Bangkok was also estimated. The value  comparatively high.  0aAirxPollutionxThailandxBangkok 0aAcid depositionxThailandxBangkok1 a I, Fude,eChairperson1 aOrth, H.M.,eExamination Committee0 aPakit KiravanicheExamination Committee2 aDAAD,eScholarship Donor2 aAsian Institute of Technology.tResearch studies project report ;vno.
