New research from the University of Hawaiʻi found that Maui residents tested significantly higher for toxic metals like arsenic, manganese, and antimony compared to national benchmarks, months to over a year after the 2023 Lāhainā wildfires. Researchers link higher metal exposure to impaired lung function but have not yet determined how much contamination was caused by the fires versus pre-existing environmental conditions.
- A UH Mānoa study of 1,400 Maui adults found arsenic levels 2.2x, manganese 3.8x, and antimony nearly 40x higher than a pre-fire national health survey.
- The findings build on earlier research showing more than 1 in 5 Maui residents had reduced lung function following the fires.
- Researchers caution that wildfire health impacts extend well beyond smoke exposure when entire communities — including homes, cars, and infrastructure — burn.
- Scientists cannot yet determine how much of the toxic metal contamination was caused by the fires versus already present in the environment.
- Community health organizations like Maui Medic Healers Hui continue operating free clinics, with leaders saying the health and housing crisis remains far from resolved three years later.
