STAR Grantee Will Chair AWMA Technical Council

Delbert J. Eatough, PhDWASHINGTON (NCER) - Delbert J. Eatough, PhD, who recently completed his EPA STAR-funded research, has been named Chair of the Technical Council for the Air and Waste Management Association (AWMA). Dr. Eatough will hold this position from 2005-2008. Currently, he is Vice-Chair of the Technical Council.

Dr. Eatough is Professor of Chemistry at Brigham Young University where he has been since 1970. Previously, he was Director of the Thermochemical Institute at Brigham Young University and Research Scientist for the Shell Development Company. For more than 25 years, Dr. Eatough’s research has focused on the atmospheric chemistry of man-made emissions. He has been a leader in the development of techniques for studying atmospheric pollution and the use of these techniques in ambient and indoor environments. Dr. Eatough’s second area of interest is the application of thermodynamics to the understanding of the properties of aerosols.

Dr. Eatough made an important discovery while conducting research as part of Project MOHAVE, an air quality research program focusing on the causes of decreased visibility in the Grand Canyon National Park during the 1990s. Using methods he developed for tracking pollutants during long-range transport, Dr. Eatough was able to determine that emissions from Mexico were a major contributor of particulate matter (PM) in Grand Canyon National Park. Previously, it was thought that the Mohave Power Plant, which is upwind of the Park and emits sulfur oxides, was the primary contributor.

Recently, Dr. Eatough completed the “Relationship Between PM2.5 Semi-Volatile Organic Material, Other PM2.5 Components and Heart Rate Variability in the Elderly,” funded by the EPA STAR grants program. As a result of this research, Dr. Eatough and colleagues were able to establish state-of-the-art atmospheric monitoring facilities in Salt Lake City, Bountiful and Lindon, Utah, for determining the time- and health-relevance of continuous PM2.5 mass and composition measurements.

They were also able to:

  • Validate a new tool (RAMS) for the continuous measurement of PM2.5 mass, including semivolatile organic material;
  • Determine that semivolatiles are major constituents of the Salt Lake City aerosol, and that, previously, semivolatiles were not correctly monitored; and
  • Determine that PM2.5 may be one of several factors that influence the health endpoints of heart-rate variability and C-reactive protein levels. Heart rate variablility and C-reactive protein levels are both thought to be indicators of cardiovascular disease.

In the late 1990s, the EPA STAR grants program funded Dr. Eatough’s research on “Continuous Measurement of PM2.5 and Associated Semi-Volatile Particulate Species.”

Dr. Eatough is the recipient of several honors. He received the 1980 Brigham Young University Research Award, the 1980 Calorimetry Conference First Sunner Memorial Award, the 1986 Brigham Young University Maeser Research and Creative Arts Award, and the 1993 American Chemical Society Utah Award. He is a Member of the EPA Ambient Air Monitoring and Methods Subcommittee of the Clean Air Scientific Advisory Committee, former Member of the EPA Science Advisory Board Committee on Environmental Tobacco Smoke, Member of the Air and Waste Management Association Technical Committee on Atmospheric Chemistry, and Member of the Editorial Boards of Aerosol Research & Technology and Journal of the Air and Waste Management Association.

Dr. Eatough received a PhD in Physical Chemistry from Brigham Young University in 1967. Additional sources of support for his research include the EPA EMPACT Program, Desert Research Institute, National Science Foundation, and U.S. Department of Energy. Dr. Eatough is the author or coauthor of more than 300 publications.
