Abstract"Acid-rain" is causing problems in industrial cities and this has been blamed on the increased burning of sulfur containing fuels. This study involved the four months (May through August, 1976) sampling and analysis of particulates and rainfalls at 9 stations in Bangkok to determine the acid contents . The street level and ambient level concentration of particulate acidity observed in Bangkok are not excessive and are comparable to those reported for other urban cities in the world and are of the order of 5.38 3 10.15 µg/m and 5.84 µg/m3 respectively. The weighted average concentration of acidity of rain water at the nine sampling stations ranged between pH 6.32 (at Samsen Road) and pH 5.57 (at Bangna Meteorological Department). At the latter station, a minimum pH value of 4.45 was also recorded. A regression line fitted to all stations weighted average of pH values versus acid contents of particulate yielded the following relationship. (pH value) 6.7 - 0.09 (Acidity of Particulates) (µg/m3)
