Air Toxics

​William Lambert served as a member of the ATSAC since its inception in 2004, though 2013. He has agreed to serve another three-year term with ATSAC, and will serve as chairperson. He is an Associate Professor in the Department of Public Health and Preventive Medicine at Oregon Health and Science University. From 1987 to 2000, he held faculty and research positions at the University of New Mexico School of Medicine. He received his Ph.D. from the Department of Epidemiology and Environmental Analysis at the University of California, Irvine and a BA degree from the Department of Biology at the University of California, Los Angeles.

His areas of expertise are air pollution epidemiology, exposure assessment, toxicology and biostatistics. He has served on a number of advisory/regulatory committees, including Chair of the City of Albuquerque/Bernalillo County Air Quality Control Board, a principal author of state of the science reviews for the American Thoracic Society's Environmental Health Committee, and as member of the Childhood Lead Poisoning Taskforce, Children's Environmental Improvement Project, and Turning Point Environmental Health Initiative in New Mexico. Currently, he is Chair of the Board of Directors for the Josiah Hill III Clinic in Portland. His community service has been recognized by several organizations, including the Clean Air Award of the American Lung Association of New Mexico and the Lifesaver Award of the New Mexico Chapter of the American Cancer Society.

Dean B. Atkinson previously served on the ATSAC from June 2009 through 2013. He is an Associate Professor of Chemistry at Portland State University in Portland, OR. He received his Ph.D. in Physical Chemistry from the University of Arizona in Tucson in 1995, where he studied the low-temperature kinetics of atmospherically relevant reactions (primarily involving OH radicals) with Dr. Mark A. Smith. He had a two-year NRC Postdoctoral Research Assistantship at The National Institute of Standards and Technology in Gaithersburg, MD, where he worked with Dr. Jeffrey W. Hudgens on methods for measuring reaction kinetics of free radical reactions, predominantly using pulsed laser photolysis/cavity ring-down spectroscopy. After starting at PSU, he built on that work and became one of the acknowledged experts in the application of the cavity ring-down method, particularly as applied to environmentally related measurements. Since much of his work at PSU has centered on atmospheric chemistry and physics, he has developed some expertise in this area, particularly in methods used to measure atmospheric species (e.g., trace gases, radicals, particulate matter.) He is familiar with the methods used to model the atmosphere, although his research has not involved the application of those methods to date.

The Atkinson group was funded by The National Oceanic and Atmospheric Administration to produce a new type of airborne cavity ring-down instrument for measuring the optical properties of the aerosol aloft. The measurements made possible by this instrument should help to clarify both the direct and indirect radiative forcings associated with particulate matter, currently the largest single unknown in the estimation of global climate change. A prototype of the instrument was used for an EPA funded field study in Portland investigating the ambient aerosol optical properties and whether they can be used as a "signature" for diesel PM. This instrument was also used in the TRAMP (TexAQS II Radical and Aerosol Monitoring Project) portion of the TexAQS II field intensive during the summer of 2006.

Current research projects focus on the use of the cavity ring-down technique to investigate air quality and climate change in the context of aerosol effects and the measurement of ambient atmospheric benzene levels in Portland.

Dave Farrer previously served on the ATSAC from December 2009 through 2013. He is a public health toxicologist for the Oregon Health Authority, where he has worked for seven years on human health risk assessment, risk communication, and production of public health assessment documents for the general public, with a special focus on Superfund and other hazardous waste sites. He also provides ongoing assistance to the Oregon DEQ and USEPA, related to the technical areas discussed above. He received his BS degree from Brigham Young and his MS and PhD in Toxicology from the University of Rochester and has authored several peer-reviewed and numerous government publications. He has been an Associate Member of the Society of Toxicology since 2002.

Bruce Hope is a principal environmental toxicologist in CH2M HILL’s Portland, Oregon, office where he works on projects involving environmental toxicology, ecological and human health risk assessment, chemical bioaccumulation modeling, development of air and water quality guidelines, and regulatory-science policy strategies. From 1995 to 2011, he was a senior environmental toxicologist with the Oregon Department of Environmental Quality where he was instrumental in identifying persistent pollutants in Oregon’s municipal effluents, developing ambient benchmark concentrations for air toxics, completing the Umatilla chemical weapons incinerator post-trial burn risk assessments, and reviewing human health and ecological risk assessments. Prior to joining DEQ, he was a consultant in the private sector managing human health and ecological risk assessment projects for commercial and government clients throughout the U.S. and the Pacific Rim. In 2000-01, he was an American Association for the Advancement of Science risk policy fellow in Washington DC, working on food safety, microbial risk assessment and bioterrorism issues.

He has served on the North American Board of Directors for the Society of Environmental Toxicology and Chemistry, is on the editorial board of Human and Ecological Risk Assessment, and was previously on the editorial boards of Environmental Toxicology and Chemistry, and Risk Analysis. He also served on several U.S. EPA national advisory and review panels addressing cumulative risk, wildlife, ecological, probabilistic, and environmental modeling issues, as well as on two National Research Council committees: one evaluating human health risk assessment practices and the other examining ecological risk assessment in the context of The Federal Fungicide Insecticide and Rodenticide Act and the Endangered Species Act. He holds M.S. and Ph.D. degrees in biology from the University of Southern California and a B.A. degree from the University of California at Santa Barbara.

Max Hueftle is a Senior Environmental Engineer, Permit Section Manager and Air Toxics Coordinator for Lane Regional Air Protection Agency. Hueftle has been an Environmental Engineer with LRAPA since 1998. He writes permits and reviews applications for commercial and industrial sources of all sizes and many different types. He has also been the Air Toxics Coordinator for LRAPA since 2000 with focus on the promulgation of recently issued federal toxics standards, responding to questions from the public and industry regarding toxics, and operation a portable Gas Chromatography/Mass Spectrometer monitoring device called the HAPSite. He was promoted to Permit Section Manager of LRAPA in 2013. He was also a member of the DEQ Air Toxics Advisory Committee, which was a predecessor committee to the ATSAC, from November 2000 to March 2002 as an assistant/backup for the LRAPA Director.

Prior to working at LRAPA, he worked in the private sector managing a nickel-plating process at a computer hard-drive manufacturer in Eugene for two years. He has a B.S. in Chemical Engineering from the University of Idaho and is a licensed Professional Engineer in Environmental Engineering.
