1. CALIBRATING CONCERN ABOUT PAHS IN URBAN AIR USING MONITORING AND MODELING: A PROJECT PLAN SUMMARY Funding: U.S. EPA Community Air Toxics Ambient Monitoring Grant # XA00E00976 Passive Monitors: donated by Oregon State University, Simonich Environmental Chemistry Laboratory

2. Size Matters Ambient Temperature Matters Branching Matters Substitution Matters Cancer Potency Matters

3. Kristie Ellickson, Greg Pratt, Cassie McMahon, Mike Bauer, and (potentially a new planner from the air policy unit) Carl Herbrandson Paul Swedenborg, Mike Krause, Christina Rainaldo, Wyatt Hedine Charlie Lippert Project Team

17. Calibration of Passive Samplers C PAS = mass of specific PAH on passive sampler media (ng) C AIR = concentration of specific PAH in air (ng m -3 ) But, we may have to adjust for calculate an effective air volume
