Particulate Matter: Spotlight on Health Protection

Increasing evidence shows health impacts from particulate matter, or PM, can occur well below the current national ambient air quality standards. As impacts in our communities increase with our changing climate, it is important that we reassess the health effects of PM.

This year, the Air District’s Advisory Council will be convening a four-part conference series on PM to facilitate a discussion among nationally recognized scientists, stakeholders, and the Air District to identify the most effective measures to further protect public health. The symposia will shine a spotlight on this public health challenge and share information and tools to inform future policy decisions.

The first symposium in the series took place on October 28, 2019 from 9 AM to 4:30 PM, at the Bay Area Metro Center, 375 Beale Street, San Francisco, California.

The second symposium will be scheduled in the first quarter of 2020, more details will be updated on this page.

Topics will include:

  • PM health effects:
    • observed health effects from PM exposure
    • affected biological systems
    • knowledge about the mechanisms
    • population groups most at risk
    • most relevant sensitivities and uncertainties
  • PM exposure and risk:
    • PM emissions and sources
    • PM levels in the air
    • community exposure
    • current understanding of PM health risks
    • economic and other costs

Oct. 28 event speakers included:

Dr. H. Christopher Frey is the Glenn E. Futrell Distinguished University Professor of Environmental Engineering in the Department of Civil, Construction, and Environmental Engineering at North Carolina State University. Dr. Frey’s research includes quantification of uncertainty in engineering process technologies and emission factors, probabilistic methods for exposure assessment, measurement and modeling of human exposure to air pollution, and measurement and modeling of vehicle emissions. Dr. Frey also is an adjunct professor in the Division of the Environment and Sustainability at the Hong Kong University of Science and Technology, where he is part of a large team developing an exposure model for Hong Kong. Dr. Frey is a Fellow of the Air & Waste Management Association and of the Society for Risk Analysis. He has a B.S. in mechanical engineering from the University of Virginia, a master of engineering in mechanical engineering from Carnegie Mellon University, and Ph.D. in engineering and public policy from Carnegie Mellon.

Scott Jenkins

Dr. Scott Jenkins is a senior environmental health scientist in EPA's Office of Air Quality Planning and Standards (OAQPS). He is currently leading EPA’s review of the National Ambient Air Quality Standards (NAAQS) for Particulate Matter (PM). Over the past 15 years, he has also worked on reviews of the NAAQS for other criteria pollutants, including ozone and nitrogen dioxide, and on standards for air toxics. Dr. Jenkins came to OAQPS from the EPA’s Office of Research and Development. Prior to EPA, Dr. Jenkins was a Howard Hughes Postdoctoral Research Fellow in the Department of Cell Biology at Duke University. His PhD is in Behavioral Neuroscience from the University of Alabama at Birmingham and his bachelor’s degree is in Psychology from Furman University.

Michael T. Kleinman

Michael T. Kleinman is UC Irvine Professor of Environmental Toxicology and Co-Director of the Air Pollution Health Effects Laboratory in the Department of Community and Environmental Medicine, Adjunct Professor in College of Medicine. He received a Ph.D. in Environmental Health Sciences from New York University. Dr. Kleinman brings expertise on the health effects of air pollution on animals and humans, as well as the development of analytical techniques for assessing biological and physiological responses to exposure to environmental contaminants and for determining concentrations of important chemical species in air. His current studies involve the inhalation exposures to manufactured and combustion-generated nanomaterials fine and coarse particles using state-of-the-art field exposure systems and real-time physiological monitoring methods. Biological mechanisms related to oxidative stress have been identified after particulate matter exposure, and Dr. Kleinman’s team is also pursuing how these mechanisms affect pathological and physiological changes in the heart and lungs. He currently serves on the Air District Advisory Council.
