The purpose of this study is to evaluate the PM2.5 concentrations improvement by application of reduction technology such as plasma DPF and hydro carbon SCR (HC-SCR) for construction vehicles. To do this, we have built a 3D air quality modeling system (WRF-SMOKE-CMAQ) and investigated emission characteristics for construction vehicles. At first, we have estimated PM2.5 based on 2016 national emission inventory, and we evaluate the reduction amount of air pollutants (PM10 and PM2.5, NOx) by application of plasma DPF and HC-SCR. The reduced concentration for PM2.5 due to the application of each technology were analyzed with various application scenarios. As a result, we found that the application of plasma DPF was more efficient to reduce the PM2.5 concentrations in the metropolitan area (Seoul 0.83 μg/m3, Gyeonggi 0.56 μg/m3, Incheon 0.54 μg/m3). However, in the case of Jeonbuk and Jeonnam, Gyeongbuk and Gyeongnam, the effective reduction of PM2.5 concentrations by construction vehicles emissions can be expected when plasma DPF and HC-SCR are applied simultaneously (Jeonbuk 0.30 μg/m3, Jeonnam 0.20 μg/m3, Gyeongbuk 0.33 μg/m3, Gyeongnam 0.33 μg/m3). We expect the results of this study can provide a valuable scientific background in developing air pollutant control technology, and policies for air quality improvement. KCI Citation Count: 2
