The aftermath of the Palisades Fire has left toxic debris on Los Angeles beaches, prompting concerns about ocean contamination. Ash from burned homes, including hazardous materials, threatens marine life and public health. Recent heavy rainfall and mudslides worsen these risks as runoff potentially carries pollutants into the ocean. Influential agencies are working on measures to sample water for toxins. While tests so far show no immediate health hazards, experts warn of long-term consequences, including possible contamination of the food chain. Researchers are investigating how urban fire impacts aquatic ecosystems in the face of disaster-induced pollution.
