A new University of Hawaii study found toxic metals still in the bodies of Maui residents long after the 2023 fires, bad news for survivors who thought the health risk ended with the smoke.

• 1,400 Maui adults had high levels of several metals 6 to 18 months after the fires.
• Some also showed abnormal lung function.
• Urban fires leave contamination behind in ash, dust, soil, debris, burned homes, and cars.
• Researchers caution the metals come from a mix of sources, and some exposure may predate the fires.

Outlook: Expect more pressure for long-term health monitoring and cleanup on Maui as follow-up testing continues.
