Proposed research areas of highest priority
Proposed Research Areas of Highest Priority

  • Driven by:

    • ORD Clients: OAQPS, States/Local/Tribes, ORD Internal Needs

    • Implementation Needs

    • CENR PM Strategy; NARSTO Assessment

  • Overall Approach:

    • Fundamental Understanding

    • Focus on Standards and Reference Materials


Proposed research areas of highest priority1
Proposed Research Areas of Highest Priority

  • Carbonaceous 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 priority2
Proposed Research Areas of Highest Priority

  • Highest 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)


Proposed research areas of highest priority3
Proposed Research Areas of Highest Priority

  • Highest 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 priority4
Proposed Research Areas of Highest Priority

  • High Priority Areas

    • Continuous Methods for Mass, Major Components of PM Fine and Coarse,and Physical Properties

    • Gas Phase Precursors: Continuous and Integrated

    • Others
