Maui study links elevated metals with poorer lung function
A study announced September 28 reports an association between elevated metal levels and abnormal lung function among Maui residents examined after the 2023 wildfires. The researchers cannot separate the fire’s contribution from earlier pollution, local geology, diet and other exposures. The result makes longer-term exposure a question for follow-up, but it does not establish that the fire caused the metal burden or the lung findings.

Metal levels and lung findings coincide
A study announced on September 28 reports elevated metal levels among Maui residents examined after the 2023 wildfires and an association between higher metal burden and abnormal lung function. The University of Hawaiʻi described the finding, and Gizmodo independently reported it after speaking with the researchers. The association is a health finding from the post-fire period. It does not show that the fire itself caused either the measured metals or the lung findings.[1], [2]
The exposure source remains unsettled
The researchers say metal exposure on Maui can have several origins. Pollution from earlier agricultural or industrial activity, local geology, diet and other environmental sources may have contributed before the fire. The disaster may also have released new contaminants or moved existing ones through soil and dust. Without measurements from the same people before the fire, its share of the burden cannot be separated from those other possible sources.[1], [2]
Researchers turn to longer follow-up
The findings concern a fire that burned a developed community, where homes, vehicles and other materials can add to the exposure landscape. Gizmodo's interviews emphasize that a level measured months later need not mean the same material stayed in a person's body since the day of the fire; exposure may have continued or recurred. The University of Hawaiʻi describes further environmental sampling and longer-term follow-up as ways to identify the sources and track health. Those steps address what this association alone cannot settle.[1], [2]
