This feasibility study is in collaboration with the European Union's project on air pollution. The main objective is to understand the relationship between environmental concentration and population exposure. (1) Our field experiments were based on the sampling methodology developed by EU. We compared the sampling results to the continuous monitoring data collected at the air monitoring network in Taipei and Kauoshung city. We then drafted a standard method for outdoor microenvironmental monitoring of PM2.5 and NOX. (2) Using Taipei city as an example, we demonstrated the feasibility of setting up a technical platform for exposure assessment. This platform is based on the GIS technology and integrated the information of population density, traffic flow data, and pollutant spatial distributions which were obtained from data collected from current air quality monitoring network. (3) Finally, we compared the differences between the air dispersion models and land use regression models in Taiwan to those in the EU. We further proposed how to incorporate the concept of exposure assessment into our national air quality management policy.
