from Science Friday · host Science Friday

This time last year, Los Angeles was on fire, and more than 16,000 homes and buildings burned to the ground. Cars, batteries, solar panels, insulation, and cleaning supplies went up in flames, releasing chemicals like lead, benzene, and asbestos into giant smoke plumes that wafted across the city.A year later, scientists are trying to understand the fallout of this urban wildfire—what chemicals got left behind, how to remediate them, and the threats to our health. Host Flora Lichtman talks with Yifang Zhu and Francois Tissot, who are at the forefront of this research. And for one of them, this work is personal.Guests:Dr. François Tissot is a professor of geochemistry at Caltech in Pasadena, California. Dr. Yifang Zhu is a professor of environmental health sciences at the University of California, Los Angeles.Transcripts for each episode are available within 1-3 days at sciencefriday.com.Subscribe to this podcast.
