St. Louis' Soulard air quality reflects the historic antebellum neighbourhood adjacent to the Anheuser-Busch Brewery, with vehicle traffic on the surrounding arterials and the brewery's distinctive yeast and malt fermentation operations contributing unique organic aerosol emissions alongside primary vehicle sources. The flat terrain allows reasonable dispersal, while the brewery's distinctive organic emission profile makes Soulard one of the US's more characterfully brewing industry-influenced urban neighbourhoods throughout the year.
