The research comes from the University of Hawaiʻi at Mānoa's Maui Wildfire Exposure Study (MauiWES), according to Medical Xpress, which reported that the health consequences of catastrophic wildfires burning through towns and cities may extend long after the flames are extinguished and the smoke disappears.

STAT reported that the risk from toxic metals can persist for months after wildfires, and that the study suggests post-wildfire air quality needs to be monitored over the long term after finding Maui residents had high levels of toxic metals months after the fires.
