The 2023 wildfires on the Hawaiian island of Maui exposed residents to a complex mix of smoke and ash. A study reported by MedPage Today and published in PNAS found that up to 18 months later, local residents had elevated urinary levels of several metals, including antimony, manganese, barium, and arsenic.
The elevated metal levels were associated with abnormal lung function, according to the study. The findings suggest that wildfire-related metal exposure may have lasting respiratory health effects, even well after the immediate disaster has passed.
