2. Background Particle exposure pollution (>2.5 microns in diameter) can cause health issues with the heart and lung. Sources of fine particles (PM 2.5) include all types of combustion activities: Motor vehicles Power plants Wood burning 2

3. PM 2.5 Air Monitoring Stations in California California Air Resources Board measures pollutants at over 50 sites PM 2.5 mass concentrations are collected at National Air Monitoring Stations (NAMS) and State and Local Air Monitoring Sites (SLAMS) 3

4. PM 2.5 Averages Throughout California Maximum: 21.2 µg/m 3 (Kern) Minimum: 3.3 µg/m 3 (Lakeport) California Average: 10.95 µg/m 3 LA County Average: 13.2 µg/m 3 (across 6 sites) 4

Additional Information SKILLS USED 1.Inset map 2.Graduated Symbols – Graduated symbols represent AVERAGE PM 2.5 therefore they were given a subtle grey outline to represent interpretation of averages 3.Boundary sub-sets selection (Kern and LA county was derived from selecting counties in the view of California and was converted to a shapefile) 4.Buffering – Slide 6 and Slide 7 show major roadways that exist within the one mile buffer (the one mile buffer was not shown on these maps in an attempt to keep the presentation simple) 5.Geoprocessing (Clip California and US States Layer with caliDetail) 6.Geocoding (Air Monitoring Stations added using X Y coordinates) REFERENCES California Enviornmental Protection Agency – Air Resources Board - http://www.arb.ca.gov/research/aaqs/aaqs.htm Census Tiger / Line Data (2009) - http://www.census.gov/geo/www/tiger/tgrshp2009/tgrshp2009.htmlhttp://www.census.gov/geo/www/tiger/tgrshp2009/tgrshp2009.html National Atlas Mapping Professionals - http://www.nationalatlas.gov/pros.html Benton Clean Air Agency (Image of size comparison; slide 2) http://bentoncleanair.org/air-quality/air- pollutants-frequent-questionshttp://bentoncleanair.org/air-quality/air- pollutants-frequent-questions Butte County Air Quality Management District (image; title slide) - http://www.bcaqmd.org/page/monitoring-air-quality.php http://www.bcaqmd.org/page/monitoring-air-quality.php Image of LA downtown (slide 2 & slide 10) – Caitlin Morrison Image of Compton MLK Monument - http://en.wikipedia.org/wiki File:Compton_martin_luther_king_monument.jpghttp://en.wikipedia.org/wiki Image of Bakersfield - http://en.wikipedia.org/wiki/File:Bakersfield_CA_-_sign.jpghttp://en.wikipedia.org/wiki/File:Bakersfield_CA_-_sign.jpg 10
