| Abstract | Major crop in Pathumthani is rice paddy which is about 94 % of total crop production per year. In dry weather conditions, rice straw remaining in paddy field after harvesting is burned. It releases large amounts of air pollution which may cause serious effects on air quality, public health and climate. In this study, both field and laboratory experiments were carried out to provide characterization of the air pollution emitted from this burning source. The field sampling produced the profiles of PM (TSP, PMl0-2.5 and PM2.5) and VOC emission. In PM source profiles, it was found that K+ is the most abundant species. Seven P AH compounds consisting of fluorene, phenanthrene, anthracene, fluoranthen, pyrene, BaA, and chrysene were detected. Nine PCB compounds including PCB 18, PCB 28, PCB 31, PCB 52, PCB 44, PCB 101, PCB149+118, and PCB 153, were detected. And seven Pesticides (cx-BHC, ')'-BHC, heptachlor, aldrin, heptachlor epoxide, endosulfan II, and DDD,) were found in field sample. Among semi-volatile organic compounds, phenanthrene, PCB 52, and heptachlor is the most abundant P AH, PCB and pesticide respectively. Laboratory experiment produced emission factors of the pollutants including SPM, ionic compounds, P AHs compounds, and BTX which are 2, 181 mg, 44 mg, 34 mg, and 263 mg per every m2 of rice straw paddy burnt, respectively. The annual pollution loads from rice straw burning to the air are 2,400 tons of SPM, 48 tons of total ionic species, 3 8 tons of total P AH compounds, 287 tons of BTX, 23,400 tons of CO, 3,000 tons of CH4, and 323,200 tons per year of C02. Analysis of correlation between ground air pollution data at a station in Pathumthani and number of hot spots from MODIS satellite was carried out and the obtained correlation coefficient between CO and hotspot was 0.56 and between PMIO and hotspot was 0.77. Forward trajectories using the HYSPLIT model were used to determine the dispersion path way of smoke from biomass burning in Pathumthani. The result illustrates that pollutant from this source can transport to neighboring area especially, the Bangkok Metropolitan Region (BMR). It is essential to develop a strategy to manage air pollution from open agro-residue burning to minimize the effects (impose scheduled burning) or minimize the amount of residues burnt (promotion of alternative utilizations of agricultural wastes. |
