Ambient VOC concentrations measured at Windsor West Station from 2001 to 2009 were used for a VOC source apportionment study using Chemical Mass Balance model. The ranking of source contribution estimates was: "Vehicle Emission", "Commercial Natural Gas", "Industrial Refinery", "Liquefied Petroleum", "Coke Oven", "Architectural Coating", and "Biogenic Emission". From 2003 to 2009, PAMS measurements in Windsor decreased by approximately 37%. Source contribution reduction of "Vehicle Emission" accounted for 57.6% of total source contribution reduction. Source contribution reduction percentages of "Vehicle Emission", "Architectural Coating", and "Biogenic Emission" were above PAMS reduction percentage; however, source contribution reduction percentages of "Commercial Natural Gas", "Industrial Refinery", "Coke Oven", and "Liquefied Petroleum" were below it. From 2001 to 2009, a seasonal pattern of PAMS measurements with low level in winter and spring but high in summer and fall was observed in some years. A similar seasonal pattern of "Vehicle Emission" source contributions was also obeserved in most years.
