The exposure to high levels of lead and other toxic metals poses severe health risks, including developmental issues in children, increased blood pressure in adults, and potential cancer risks from arsenic. The fires destroyed over 16,000 structures, releasing harmful chemicals from burning materials like paint, electronics, and furniture. Millions of residents in Los Angeles were directly affected, with long-term health implications still uncertain. The study emphasizes the need for improved monitoring and emergency response to mitigate these risks.
