Abstract: The observational data set of ambient PM10 concentrations from monitoring stations in Saraburi during 2001 to 2005 was analyzed to investigate the spatial and temporal variations. The result shows that Nah Phra Laan sub-district and its vicinity, mineral products industrial area in Saraburi, is very serious area for particulated problem. During 2001 – 2005, the PM10 concentrations at Nah Phra Laan site exceeded annual standard of 50 ug/m3 every year. PM10 levels show strong spatial variation that can be attributed to low wind speed and coarse particulate matters emitted from crushed stone plants and re-suspended dust from roads. The result reveals that local sources are main contributors of PM10 in Nah Phra Laan’s atmosphere. Monthly average PM10 concentrations show strong seasonal variation. Annual average PM10 concentrations in winter, summer, and rainy season were 102.3+-66.0, 80.3+-44.8 and 86.8+-38.7 ug/m3, respectively. Higher PM10 concentration in winter is due to less precipitation, weaker wind speed, and lower temperature. The diurnal variations of PM10 concentrations characterize by two peaks at around 9.00-11.00 and 7.00-900 PM that are associated with high emission rate and accumulated condition (low wind speed and short mixing height). The difference of diurnal variations in each season is found with the high variation in winter and the low variation in summer
