Air Quality

“If you’re 100 meters from the freeway or 500 meters from the freeway, there’s a total difference in your level of exposure,” said Suzanne Paulson, a professor of atmospheric chemistry and director of the Center for Clean Air at UCLA. Read more

We believe that the process of unconventional fossil fuel development including shale tight oil and gas development in the Monterey Shale formation using hydraulic fracturing, acidization, and other forms of well stimulation will exacerbate many of these environmental threats, particularly climate disruption, local air and water pollution, and resource consumption. Thus, the decisions you make about the development of unconventional oil and gas production from shale in California will hold important consequences for California and the state’s future.

Abstract: Current literature is insufficient to make causal inferences or establish dose-response relationships for traffic-related ultrafine particles (UFPs) and cardiovascular (CV) health. The Community Assessment of Freeway Exposure and Health (CAFEH) is a cross-sectional study of the relationship between UFP and biomarkers of CV risk. CAFEH uses a community-based participatory research framework that partners university researchers with community groups and residents. Our central hypothesis is that chronic exposure to UFP is associated with changes in biomarkers.

Just beyond the front door of the Montessori School at Five Canyons, a square glass-walled foyer is brimming with verdant houseplants in clay pots. Garden sculptures and glazed ceramic art are interspersed throughout. Above it all floats the looped sound of softly chirping birds. This lush tableau provides a fitting transition between the world outside and the carefully controlled atmosphere within, where child care director Meher Van Groenou has made environmental health one of her top priorities.

Low-income neighborhoods are more often exposed to poor environmental quality when compared to wealthier communities, and scientists are saying this gap will increase as climate change is more widely felt.

Diesel-powered vehicles are a significant source of pollution, impacting health and contributing to climate change. The Ditching Dirty Diesel Collaborative, a coalition of community, environmental advocacy and public health departments, is working together with the Pacific Institute to reduce the impact of this pollution on low-income communities in the San Francisco Bay Area.

Los Angeles, California, is one of the biggest transportation in the world, but that has major health implications for residents. Exposure to diesel fumes has an impact on everyone, and Switzer Fellow Scott Fruin documents those effects, especially on children.
