Researchers Provide New Insight into Formation of Secondary Organic Aerosols in Atmosphere; Implications for Health and Climate Models

Green Car Congress A new study led by a team from the University of California, Irvine is providing important new insight into the mechanisms by which secondary organic aerosol (SOA) particles form and grow. The work, published in the Proceedings of the National Academy of Sciences, has implications for model formulations of SOA, both outdoors and indoors, and the associated health and climate impacts predicted based on those model outputs. Airborne particles have significant impacts...

‘Sticky Smog’ Might Help Solve Smoggy Mystery

Pat Brennan, Orange County Register The hazardous gases that make up Southern California’s smoggy haze might stick together like tar, not dissolve inside droplets, a new study by UC Irvine scientists shows. And while that might sound like splitting hairs, it could have profound implications for how we understand smog and forecast its effects. The finding, by UCI chemistry professor Barbara Finlayson-Pitts and a team of researchers, might help solve the mystery of “missing”...

Gases Drawn into Smog Particles Stay There, UCI-Led Study Reveals

Finding could explain why air pollution models underestimate organic aerosols Janet Wilson, UC Irvine Today Airborne gases get sucked into stubborn smog particles from which they cannot escape, according to findings by UC Irvine and other researchers published today in the Proceedings of the National Academy of Sciences. The results could explain a problem identified in recent years: Computer models long used by the U.S. Environmental Protection Agency, California air regulators...

Chemists discover ozone-boosting reaction

It’s a recipe for choking smog. Burn tons of fossil fuels. Pump those chemicals into the air where they react on surfaces of buildings and roads. A result is the creation of photochemical smog-forming chlorine atoms, UC Irvine scientists report in a new study. Jennifer Fitzenberger, University Communications It’s a recipe for choking smog. Burn tons of fossil fuels. Pump those chemicals into the air where they react on surfaces of buildings and roads. A result is the creation of...
