Health effects of airborne particulate matter near the Salton Sea: A Community-based exploratory project in the Imperial Valley, CA. The Salton Sea is a man-made, saline lake, located in southeastern California, in the Imperial and Coachella valleys. As a result of climate change, drought, agricultural practices, rural-urban water transfers, the Salton Sea is a polluted and shrinking lake. Communities are concerned about high rates of asthma and the potential role of the Salton Sea as a source of air pollution, both from hydrogen sulfide from the lake bed, and airborne dust and toxic particulate matter, and other health hazards stemming from the lake’s deteriorating water quality and increasingly exposed banks. For this project, Dr. Pinkerton and his team are investigating how particulate matter (ambient PM2.5 and PM10) might sensitize the immune system to house dust mite (HDM) allergen. In particular, the researchers are interested in understanding the role of inflammation, oxidative stress and other pathways of PM-mediated immunotoxicity in the Imperial Valley. The team is working in collaboration with The Environmental Justice Coalition for Water (EJCW) and Comité Cívico del Valle (CCV), and the communities of of Brawley and Calipatria.
The first ever UC Davis Environmental Health Sciences (EHS) Academy Day on March 21 brought together multi-disciplinary researchers and community-based organizations to discuss concerns about environmental health impacts, specifically those centered on water safety and contamination issues in the Central Valley. Academy Day provided attendees with opportunities for mutual learning and information sharing. The aim was to get individuals thinking about how scientists and communities can work together to solve environmental problems and translate science into action and policy.
