Toxicological Evaluation of Realistic Emissions of Source Aerosols (TERESA): Application to Power Plant-Derived PM2.5

PDF Version Also Available for Download.

Description

This report documents progress made on the subject project during the period of September 1, 2007 through February 28, 2007. The TERESA Study is designed to investigate the role played by specific emissions sources and components in the induction of adverse health effects by examining the relative toxicity of coal combustion and mobile source (gasoline and/or diesel engine) emissions and their oxidative products. The study involves on-site sampling, dilution, and aging of coal combustion emissions at three coal-fired power plants, as well as mobile source emissions, followed by animal exposures incorporating a number of toxicological endpoints. The DOE-EPRI Cooperative Agreement ... continued below

Description

This report documents progress made on the subject project during the period of September 1, 2007 through February 28, 2007. The TERESA Study is designed to investigate the role played by specific emissions sources and components in the induction of adverse health effects by examining the relative toxicity of coal combustion and mobile source (gasoline and/or diesel engine) emissions and their oxidative products. The study involves on-site sampling, dilution, and aging of coal combustion emissions at three coal-fired power plants, as well as mobile source emissions, followed by animal exposures incorporating a number of toxicological endpoints. The DOE-EPRI Cooperative Agreement (henceforth referred to as ''the Agreement'') for which this technical progress report has been prepared covers the performance and analysis of field experiments at the first TERESA plant, located in the Upper Midwest and henceforth referred to as Plant 0, and at two additional coal-fired power plants (Plants 1 and 2) utilizing different coal types and with different plant configurations. During this reporting period, fieldwork was completed at Plant 2, located in the Midwest. The following scenarios were completed: (1) July 19-22: POS (oxidized + SOA); (2) July 25-28: PONS (oxidized + neutralized + SOA); (3) August 8-13: P (primary); (4) August 14-15: POS; (5) August 16-17: POS (MI rats); (6) August 28-31: OS (oxidized + SOA, without primary particles); (7) September 1-4: O (oxidized, no primary particles); (8) September 6-9: S (SOA, no primary particles); and (9) September 19-22: PO (oxidized). Results indicated some biological effects with some scenarios. Also during this reporting period, the annual meeting of the TERESA Technical Advisory Committee was held at the Harvard School of Public Health in Boston. During the next reporting period, data analyses will continue for Plant 2 as well as for pooled data from all three plants. Manuscripts documenting the overall project findings will be prepared for submission to the peer literature. Preliminary planning will begin for the mobile source component of the research (funded through the Harvard-EPA Center for PM Health Effects), scheduled to take place in 2008.
