Summary: | 碩士 === 萬能科技大學 === 環境工程研究所 === 105 === In this study, the spectral analytical method was successfully applied to estimate the contribution ratio of different sources to the air pollutant concentrations monitored by a air quality automatic monitoring station. To reduce the interference caused by weather conditions, the Ventilation Index correction factor was developed to modify the original monitoring data. Such modification was further confirmed to be necessary since significant differences were identified between the two group of time series data. By comparing the wave frequency of the CO time series data collected from Yuen-Ho monitoring station, a traffic source station, the characteristic wave frequencies which were obtained by applying the emission scenario for both mobile and stationary sources were confirmed. The estimation of amounts of source contribution to the monitored air pollutant concentrations were further confirmed by comparing the source profile of Yuen-Ho area. Accordingly, this method may aid the planning of air quality management.
