"Each of these three individuals has made a distinguished and lasting mark on California's environment,” said ARB Chairman Mary D. Nichols. “Whether in the fields of policy, research, or the development of breakthrough technologies, they have demonstrated a lifelong commitment to protecting the environment and public health.”

Dr. Joan Denton - for her work in Environmental Policy

Dr. Joan Denton award winnerDr. Denton has 29 years of professional experience and consistent accomplishment in environmental health programs.  She recently retired after 13 years as Director of the California Office of Environmental Health Hazard Assessment.  During this time she was responsible for the performance of scientific risk assessments for the regulation of chemicals in the environment, and for providing information about the health and environmental risks of chemicals to government agencies and the public.  As Director she was also responsible for providing overall scientific guidance and consultation to the Secretary of the Environmental Protection Agency and the Cal EPA Boards and Departments.  Dr. Denton was appointed and re-appointed as Director of OEHHA by 3 different governors.  During her tenure at OEHHA she was instrumental in the identification of diesel particulate matter, environmental tobacco smoke, and lead as toxic air contaminants.  California’s air quality standards for particulate matter, ozone, and nitrogen dioxide were revised to include effects on sensitive populations, including children and infants.  She also oversaw the implementation of the Safe Drinking Water and Toxic Enforcement Act of 1986, also known as Proposition 65.  We are proud that Dr. Denton was at ARB prior to her serving as Director of OEHHA.  She worked in a number of programs including, the identification of diesel particulate matter. 

Dr. Bradley Edgar - for his work in Science and Technology

Dr. Brad Egdar Dr. Edgar is co-founder and the President and Chief Technology Officer of Cleaire Advanced Emission Controls, which is based in the San Francisco Bay Area.  ARB’s diesel regulations have relied on the development and commercialization of retrofit technologies.  Over the last decade, Dr. Edgar has pioneered important breakthroughs in developing advanced technologies to reduce diesel particulates and oxides of nitrogen.  Cleaire has emerged as a leader in the diesel retrofit market, having received more than 10 Air Resources Board verifications for its products, and delivering more than 11,000 diesel retrofits into commercial use.  Dr. Edgar began researching and working in the field of mechanical engineering nearly 20 years ago and has been the inventor or co-inventor for 11 United States Patents related to emission control technology.

Dr. Edgar earned a reputation as an industry leader helping to deploy the technology needed to keep California’s air clean.  He has demonstrated leadership in the California business community helping to solve environmental problems while also contributing to economic development and job growth.  In 2008, Cleaire was awarded the Clean Air Award for Technology and Research by Breathe California in recognition of the company’s contribution to improving air quality.

Dr. John Froines - for his work in Environmental Health Research

Dr. John FroinesDr. Froines has a long history of teaching and conducting research on air pollution-related health effects.  He is a professor in the Department of Environmental Health Sciences at UCLA, having joined the faculty of the School of Public Health in 1981.  He holds several key positions in health sciences and toxicology programs including Director of the Southern California Particle Center and Supersite.  He is Associate Director of the Southern California Environmental Health Sciences Center and Director of the UCLA Fogarty Program in Occupational and Environmental Health.  Dr. Froines served as Director of UCLA’s Center for Occupational and Environmental Health Sciences for 25 years and was Deputy Director of the National Institute for Occupational Safety and Health before coming to UCLA.  He also Chairs California’s Scientific Review Panel on Toxic Air Contaminants; one of the major accomplishments of the panel under Dr. Froines’ leadership was the exhaustive review and recommendation to list diesel particulate emissions as a toxic air contaminant.

Dr. Froines’ area of expertise is toxicology and exposure assessment.  His air pollution-related research includes studying the health effects of exposure to particulate matter, lung cancer and non-cancer health effects attributable to air pollution, and the biochemical mechanism of the carcinogenicity of toxic air contaminants.

Dr. Froines’ teaching and research is highly regarded for enhancing the understanding of toxic air contaminants and their health impacts.  Through his dedication to translating scientific information in ways that are useful in public policy settings, his work has had a tremendous impact nationally and internationally.

Last year, his strong commitment to outstanding research was recognized by the South Coast Air Quality Management District with a Clean Air Award for his Promotion of Good Environmental Stewardship.
