Abstract Air pollution has become a global issue getting more public concern. Such a small island with a well-developed industry and heavy ongoing traffic like Taiwan, public attention on air quality is increasing even its air quality has been constantly improving since the last decade. To attain the national regulatory goal (15 μg/m3 for, annual average), counties in Taiwan are currently developing a series of action plan for PM2.5 emission reduction. However, considering the current air quality policies and strategies, it’s not easy to meet the national regulatory goal (15 μg/m3, annual average) in most of the geographical areas in the near future.
The purpose of this study was mainly investigating the contribution of emissions from each county to itself as well as to other counties in central Taiwan and discussing the necessity of cross-region policies by the using the Weather Research and Forecasting (WRF) model and the Community Multiscale Air Quality (CMAQ) model. This study could help understanding the impact proportion of PM2.5 emitted from point , traffic and non-point sources to the air quality. The findings of this research not only offer important insights about the air quality impacts of each country, but also provide useful information for the decision making of cross-regional policy.
