The targets of this research is to study on the particle size distribution with reviewing references and compute the contribution of particle emission from stack in every industries. Furthermore, it is necessary to study on the measuring the particle size distribution in stack at brick plant, pulp plant, fuel plant, and Asphalt plant with determining the differences of benefits and drawbacks between USEPA Method 201 & 201A-“Determination of PM10 emission」and JIS K 0302「Measuring method for particle-size distribution of dust in flue gas”. The contribution of PM10 emission from stack is also determined in this study. The results showed that PM10/TSP is between 0.71 and 0.92. The PM10 concentration, as high as 114.7 mg/Nm3, in the stack at food plant is the hightest than the other plants with USEPA Method 201. The PM10 measured at Asphalt plant with USEPA Method 201 is roughly 18 ~ 200% times larger than with JIS K 0302. The MMD of particulate in stack is 2.4, 1.5, 4.4, and 2.2 μm at brick plant, pulp plant, fuel plant, and Asphalt plan, respectively. The emission rates predicted by following USEPA Method 201 is the highest and roughly two times of the emission rates predicted by following JIS K 0302. This study also suggests that the USEPA Method 201 is suitable to measure PM10 concentration. In contrast, the JIS K 0302 is suitable to determine particle size distribution.
