To evaluate fine dust amount occurring from a construction waste intermediate treatment plant and seek measures to control fine dust occurrence, this study analyzed the fine dust occurrence situations and characteristics. The analysis results are as follows: 1) As a result of measuring fine dust using a light scattering method, PM10 showed relatively higher values in the area where there was a lot of heavy equipment access/exit and the area where comminution work was carried out and the surrounding area in terms of boundary area of the plant. Therefore control to prevent external fine dust from scattering was necessary. PM2.5 was measured at the atmosphere concentration level, and so there was almost no effect of PM2.5. 2) Concerning PM10 whose fine dust scattering effects were on the surrounding areas during the operation of the plant, a trend of fine dust concentration decrease was shown, as separation distance increased, but the high values of PM10 were shown in the areas adjacent to roads or areas where vehicles traveled, despite far separation distance. As for PM2.5, constant values were shown, irrelevant of distance, and so the operation of the intermediate treatment plant hardly affected the concentration in the surrounding area. 3) Regarding the heavy metal analysis result, the concentration of Pb was measured at 25~40ng/m3, which revealed the concentration value similar to the Pb concentration revealed in the Monthly Report of Atmospheric Environment. 4) The analysis result of SEM-EDX showed no difference of components before and after the operation.
