Outdoor Smoke Monitoring

Two reports have been released on the magnitude of outdoor tobacco smoke levels in typical locations, including private patios, airports, restaurants, and hospitals. The first report completed at Stanford University describes measurements made using real-time particle monitoring instruments that were carried by investigators to different locations where smokers were present. The second report (Part A, Exposure Assessment, Chapter V, page V-7 and Appendix C) completed by the California Air Resources Board describes integrated nicotine measurements and simultaneous counts of smokers. Nicotine is a unique indicator of the presence of tobacco smoke.
