2 Proposed Research Areas of Highest Priority rDriven by: ORD Clients: OAQPS, States/Local/Tribes, ORD Internal Needs Implementation Needs CENR PM Strategy; NARSTO Assessment rOverall Approach: Fundamental Understanding Focus on Standards and Reference Materials

3 rCarbonaceous PM, A Major Focus: New and Improved Methods, Quantifying Uncertainty, and Minimizing Artifacts for Collecting and Analyzing PM Collected on Filters for the Determination of:  Organic Aerosol and Semi-Volatile Species with an Emphasis on Source Apportionment Needs  Organic Carbon (OC) and Elemental Carbon (EC)  Biogenic vs. Anthropogenic Carbonaceous Material using Radiocarbon Methods Proposed Research Areas of Highest Priority

4 rHighest Priority Areas PMcoarse FRM/FEM Organic Carbon and Elemental Carbon Collection and Analysis Methods  Sampling Artifacts for OC When Using Quartz Filters  Artifacts in EC and OC TOA Analysis  Optimization of TOA Protocol - Fundamental Approach  Development of OC and EC Standards; PM on Filters and Synthetic  Proportionality of OC to Organic Material (account for C, H, O, N)

5 rH ighest Priority Areas (continued) Organic Aerosol Speciation with Focus on Source Apportionment  Development of Calibration Standards and Reference Materials for Source Tracer Species  Comparability Amongst Labs Nationwide Performing the Analyses (OC Workgroup)  OC Collection Methods Minimizing Interferences from SVOC Using Denuders and Reactive Filters Biogenic vs Anthropogenic Sources of Carbon  Radiocarbon Methods Proposed Research Areas of Highest Priority

6 rHig h Priority Areas Continuous Methods for Mass, Major Components of PM Fine and Coarse,and Physical Properties Gas Phase Precursors: Continuous and Integrated Others Proposed Research Areas of Highest Priority
