Maui Wildfires Linked to Long-Term Lung Health Risks
US · Published Sep 29, 2026
• A recent study published in the Proceedings of the National Academy of Sciences highlights the long-term health impacts of the 2023 Maui wildfires.
• Researchers found elevated levels of metals such as arsenic, cadmium, copper, and antimony in the urine of residents living near the affected areas, including Lahaina, Wailuku, and Kahului.

Impact & Risks

Residents near the 2023 Maui wildfire zones, particularly in Lahaina, Wailuku, and Kahului, face elevated health risks due to prolonged exposure to harmful metals in the environment. These metals, released from burned infrastructure, have been linked to respiratory issues, including reduced lung capacity and difficulty breathing. The study found antimony levels nearly 40 times higher than U.S. averages, along with significant increases in manganese, barium, and arsenic. The geographic distribution of smoke and ash suggests that those closest to the fire zones are at the highest risk. The findings highlight the broader implications of climate-related disasters, which can leave lasting health and environmental impacts.
