A mobile air monitoring station monitored air quality in Ballarat from August 2005 to August 2006. Several common pollutants with known health impacts were monitored.Ballarat’s air quality was generally similar to or better than other monitored regions in Victoria (Melbourne, Geelong and the Latrobe Valley).The results showed that Ballarat had generally good air quality during the daytime but was locally impacted by woodsmoke during the evenings, especially during the colder months of the year, and by bushfires.
