Curious about what might be in your soil after the fires? Our friends at @departmentofangels and @dornsife.usc.edu CLEAN are hosting a free community soil testing event TOMORROW in Altadena. Learn more and RSVP here: www.eventbrite.com/e/altadena-c...

“We’ve known that smoke exposure causes poor outcomes, but we haven’t understood how,” said Dr. Kari Nadeau for ABC News. “Our study fills in this knowledge gap, so that [we're] better equipped to respond to the growing threat of ... toxic wildfires.”

ABC News spoke with Dr. Kari Nadeau and Dr. Susan Cheng about their research into the health impacts of toxic exposure of wildfire smoke in firefighters. The first of its kind study found that exposure to smoke may alter the immune system on a cellular level. Watch now:

Dr. Joseph Allen from @HarvardChanEnvHlth and the LA Fire HEALTH Study, recently told ‪@insideclimatenews.org,‬ “In these national emergencies, I think all of us in this field feel compelled to do what we can to help." ‪@joeallenjoe.bsky.social.‬ Read more: insideclimatenews.org/news/2505202...

Please join researchers from the LA Fire HEALTH Study team for this panel hosted by Eaton Fire Residents United (EFRU) on Thursday, May 29th at 7pm Pacific. Learn more + register here:

New LA Fire HEALTH Study Data Brief finds low VOCs in tap water samples taken in Feb–April in Palisades and Altadena. Learn more about results and how to flush, filter, and test you tap water here: lafirehealth.org/newest-data-... #lafires #water #benzene

New data released from the LA Fire HEALTH Study on Friday shows that outdoor VOC levels during the Eaton and Palisades fires were elevated, but remained well below CA and EPA thresholds for exposure. Learn more at lafirehealth.org/data

Smoke and ash from forest fires contains very different compounds than smoke and ash from wildfires that spread into cities. These fires at the intersection of wild + urban areas burn different types of fuel (homes, cars, etc.), raising new concerns about health impacts of smoke. Read more:

New Data Brief looks at mudslide risks in wildfire areas: California's cycle of extreme rain, drought, wildfires, repeat, has compounded risks of mudslides and flooding in burned areas. New maps from LA Fire HEALTH can help planners reduce risk and rebuild safely.

The LA Fire HEALTH Study released preliminary* air quality data today for the LA area during the Palisades and Eaton wildfires in January 2025. The data shows how outdoor levels of particulate matter (PM) impacted air quality inside of homes during the wildfires. lafirehealth.org/data

What is PM? Air pollution is often measured by measuring the number of tiny particles in the air. These particles, called particulate matter (PM) are made up of a mixture of many different chemicals, including metals, carbon, and other toxins. Learn more:

What are VOCs? Volatile organic compounds (VOCs) are gases that are released into the air from solids. This can happen after structures burn during wildfires, but VOCs are also commonly emitted in homes from an array of sources like cleaning products. Learn more:

Looking for masks and PPE? The Altadena Public Library, and other LA Country Library branches have FREE N-95 and KN-95 masks for residents. recovery.lacounty.gov/2025/02/07/l...

The LA Fire HEALTH Study released its second Data Brief last week. This brief highlights the presence of VOCs and particles (PM) inside damaged homes in the burn area, and advises continued caution for residents entering affected homes.

What is LA Fire HEALTH? The Los Angeles Fire Human Exposure and Long-Term Health (HEALTH) Study is a 10-year study of the LA fires to determine which pollutants are present, at what levels, where, and how they change over time. And to evaluate their health impacts.

The LA Fire HEALTH Study is a partnership between researchers at @harvardenvhealth.bsky.social, @keck.usc.edu, @ucdavisengineering.bsky.social, @yalesph.bsky.social, @utaustin.bsky.social, Stanford, and UCLA Fielding School of Public Health. Meet the study team here:
