Abstract: Abstract: Based on an investigation of ambient total suspended particulate (TSP) matter concentrations, this study not only evaluates how the TSP levels deteriorate the air quality near Jhuoshuei River in central Taiwan, but also demonstrates that the monsoon season profoundly influences ambient TSP concentrations. Samples of ambient TSP obtained from representative areas in target areas during monsoon and other seasons in 2005–2006 were collected for use in receptor modeling. A chemical mass balance model version 8 (CMB8) developed by the United States Environmental Protection Agency, was implemented based on TSP emission information from version 5.1 of the Taiwan Emission Data System (TEDS5.1) and a source profile from SPECIATE3.2. CMB8 model estimates indicated that windblown soil coming from the Jhuoshuei riverbed largely contributed to the receptor site during the monsoon season. Statistical analysis revealed that metal species appearing during the monsoon season have a higher correlation with each other than during other seasons. The well-known fact that these elements are emitted from soil suggests that the soil source significantly contributes to TSP concentration at downwind sampling sites during the monsoon season. Moreover, the concentration of TSPs at downwind sites is significantly higher than that at upwind site during monsoons, posing a potential risk to human health in the downwind residential communities.
