It has been revealed that the importance and role of volatile organic compounds (VOCs) on ozone formation in the atmosphere for years. A total number of nine photochemical assessment monitoring stations (PAMS) were established in Taiwan for more than a decade for studying the regional high-ozone episodes and their relationships between VOCs. However, the estimation of public health risks in individual areas is yet to be well-validated. In this study, a well-testified atmospheric chemistry model, PAMS-AQM, will be employed in association with the observational data to investigate the long-term and seasonal variations of regional VOC patterns and distributions. As a result, the diffusion information derived from the model simulation could be further used for health risk calculation and shed a light on the mechanism of tropospheric ozone formation. The primary objectives of this research are listed below:The first objective of this research is to analyze and develop the long-term and seasonal changes of VOCs in individual areas. By applying model simulations, the presence of anthropogenic VOC pollutants in the atmosphere can be evaluated by using their diverse lifetimes. Further studies on deteriorated air qualities in individual regions will be focused in this study by investigating the VOCs patterns and their potentials on ozone formation.The second goal is to evaluate and simulate the changes and magnitudes of individual VOCs in association with wind field data in the impacted area for resident studies. The fingerprint databases of regional VOC concentrations can be established based on distribution analysis and their relationships in between. Finally we propose to calculate the public health risks based on the results derived from the simulation which provides the hourly diffusion information of anthropogenic VOC pollutants in individual areas. These results could provide the useful understanding and knowledge on the VOC-related environmental issues for the policymakers to make adequate abatement regulations.
