The health consequences of catastrophic wildfires that burn through towns and cities may extend far beyond the period when flames are extinguished and smoke disappears, according to new research from the University of Hawaiʻi at Mānoa’s Maui Wildfire Exposure Study (MauiWES).
The health consequences of catastrophic wildfires that burn through towns and cities may extend far beyond the period when flames are extinguished and smoke disappears, according to new research from the University of Hawaiʻi at Mānoa’s Maui Wildfire Exposure Study (MauiWES).
A study of 1,400 Maui adults 6–18 months after the August 2023 wildfires found substantially elevated concentrations of several metals in participants’ urine, and also discovered that greater amounts of metals accumulated in the body was associated with abnormal lung function. Researchers measured 24 metals while assessing pulmonary function through standardized breathing tests at the same visit. The findings were published on September 28 in the Proceedings of the National Academy of Sciences.
Compared with U.S. biomonitoring data, Maui participants had markedly higher concentrations of several metals, including antimony at nearly 40 times, manganese at 3.8 times, barium at 2.3 times and arsenic at 2.2 times U.S. reference values. Across three complementary statistical approaches, higher combined metal exposure was associated with several measures of abnormal lung function. Arsenic, cadmium, copper and antimony were among the metals that contributed most strongly to those patterns.
