Estimation of Particulate Matter Emission Factors from Open Burning

It is very important to investigate air pollutants and emissions emitted from open burning in order to control nonpoint sources effectively. In this study, we utilized incineration simulator proposed by U.S. EPA and investigated concentrations of TSP, PM10, PM2.5 from woods and household wastes burning to calculate emission factors and build emission inventories. The results of experiment with 15 kg of woods and 3 kg of household wastes using the incineration simulator were as follows: in case of woods burning, TSP concentration was 66.4 mg/m(3), PM10 concentration was 28.4 mg/m(3), PM2.5 concentration was 17.9 mg/m(3), respectively; in case of household wastes burning, TSP concentration was 118.4 mg/m(3), PM10 concentration was 66.8 mg/m(3), PM2.5 concentration was 55.2 mg/m(3), respectively. Concentrations from household burning, as stated above, were higher than those from woods burning. Emission factors (EFs) for woods and household wastes burning were calculated as 2.45 and 6.75 g/kg for TSP, 0.86 and 5.45 g/kg for PM10, 0.78 and 4.81 g/kg for PM2.5, respectively. EFs of TSP, PM10, PM2.5 calculated from household wastes burning were higher than those of woods burning. When we added PM emissions from woods burning and household wastes burning to Korean National Emission Inventory named as Clean Air Policy Support System (CAPSS), CAPSS annual emissions of TSP, PM10, PM2.5 were increased by 0.08 similar to 0.26% (An increase rate for TSP, PM10, PM2.5 were 0.08 similar to 0.10%, 0.16 similar to 0.20% and 0.18 similar to 0.26%, respectively). Note that we assumed that the 1% of household wastes is emitted by open burning.
