To estimate the association between environmental pollutant concentration and residents’ exposure, this project has conducted the sampling of environmental particulate matter (PM2.5), developed the chemical analysis of trace elements and evaluated the major source of PM2.5 and its contribution in three years, separately. Presently, the first year of this project has completed micro-environmental sampling to PM2.5 from residence and monitoring car in Taipei city, and assessed the association between the middle-long term micro-environmental PM2.5 concentration and PM2.5 concentration form air quality monitoring station. The second year of this project has completed the sampling of environmental particulate matter to PM2.5 in Kaohsiung city and developed the chemical analysis of trace elements. In this year, this project will focused on the comparison of the sampling method of micro-environmental PM2.5 and the standard sampling method of PM2.5, developed land use regression model based on trace elements and estimated the source of ambient particulate matter (PM2.5) and source contributions in urban area.
