State Senate confirms Sherriffs as air board member

The state Senate this week confirmed Dr. Alex Sherriffs as a governing board member on the California Air Resources Board.

Sherriffs is a Fowler physician and member of the governing board for San Joaquin Valley Air Pollution Control District. Known as a clean-air advocate, he was named to the local air board in late 2011 and the state board last year.

On the local board, he fills a seat dedicated to a health professions. On the state board, he is the Valley air district’s representative. There is no compensation for either position, state officials said.

UC Davis uses Fresno air to study most toxic particles

Not all pollution particles are created equally bad for you. The ones from cars, trucks, fireplaces and cooking are probably getting the worst reactions from your body.

Two University of California scientists came to the conclusion after collecting air samples from Fresno in summer 2008 and winter 2009, identifying the particles in the samples and allowing laboratory mice to inhale them.

The approach is the first of its kind, according to the UC Davis scientists, Anthony Wexler and Kent Pinkerton. Wexler is the director of the Air quality Research Center at Davis. Pinkerton is professor of pediatrics at the School of Medicine.

Their work on this study will help regulators in the future as they tighten standards to protect human health.

“Right now, air-quality standards are based on the mass of the particulate matter and don’t distinguish between natural sources, like sea spray, and known toxic sources, like diesel exhaust,” said Wexler, who led the study.

The bottom line: New standards some day might be aimed at certain types of particles, instead of all particles. It would save money for industries in the cleanup.

The study was funded by the California Air Resources Board and the Electric Power Research Institute.
