Presentation Transcript

  1. Transport and Characterization of Hazardous Substances in Arid Environments Proposal from Northern Arizona University Flagstaff, AZ Presented by Richard D. Foust, Jr. HBCU/MI Steering Committee Member

  2. Three Sub-Projects under this “Umbrella” Proposal • Biogeochemical Transformations of Arsenic in a Well-defined Ecosystem • Chemical Speciation of PM-2.5 from Prescribed Fires in the Southwest • Interfacial Chemistry of Heterogeneous Systems

  3. Biogeochemical Transformations of Arsenic in a Well-defined Ecosystem Research Objectives • Determine concentration at each trophic level in Montezuma Well ecosystem • Identify forms of arsenic within the organisms of Montezuma Well ecosystem • Understand the factors causing movement and transformations of arsenic in the Montezuma Well ecosystem

  4. Chemical Speciation of PM-2.5 from Prescribed Fires in the Southwest Research Objectives • Analyze the chemical composition airborne particulate matter generated during real and simulated prescribed fires • Analyze aerosols for polyaromatic hydrocarbons (PAHs) and test for mutagenic activity

  5. Interfacial Chemistry of Heterogeneous Systems Research Objectives • Investigate of metal speciation with respect to mobility in the environment • Measure the bioavailability of metals to microbial communities • Understand the reaction pathways, the kinetics, and the thermodynamics of metals in environmental systems

  6. Benefits to DOE • Arsenic is an international health issue and present in the ground water of many DOE facilities • Airborne particulates from the Los Alamos fire were a major concern in will be an issue in any similar events at DOE facilities • Bioavailability of metals at Hanford, Rocky Flats and the Nevada test site is governed by heterogeneous surface chemistry

  7. Deliverables • Master’s theses by well-trained students anxious to enter the DOE workforce • Well trained undergraduate students capable of entering graduate school or entering the DOE workforce • Publications in first-tier scientific journals

  8. Co-Principal Investigators • Sub-Project 1. Richard D. Foust, Jr., Professor of Chemistry and Environmental Science • Sub-Project 2. Marin Robinson, Associate Professor of Chemistry and Environmental Science • Sub-Project 3. Jani Ingram, Associate Professor of Chemistry
