This study investigates ventilation and processing methods for industrial facilities by analyzing the distribution chart and concentration of fine particles generated. Analyses of fine particles were conducted in crushing rooms, sorting room, Primary manufacturing room and packing room, where the concentration of 0.3~10.0 μm particles were measured for 10 minutes during processing of herb medicines. The result revealed that particles with sizes greater than or equal to PM2.685 took up most of the space, and the concentration of fine particles (PM10) was 1,672.24 μg/m3 in 1th crushing room, 3,144.7 μg/m3 in crushing 2nd room, 262.45 μg/m3 in sorting room, prior to processing (2,302.3 μg/m3 for Aralia continentails and 5,564.9 μg/m3 for Poria cocos), 4,656.5 μg/m3 in Primary manufacturing room, and 20,213.3 μg/m3 in packing room. The concentration of fine particles generated during manufacture of herb medicines was, in comparison to the standard of 150 μg/m3 established in the Indoor Air Quality Control Act, 1.7 to 135 times higher. High concentrations of fine particles were found in all rooms, except for packing, even with partial ventilation. Also, it can be inferred that adequate deodorization system may be required in order to control unpleasant herb odors. Through this study, it is recommended that the use of scrubbers and concealment may facilitate control of fine particles containment.
