# Toxic Metal Exposure Persists Long After Maui Wildfires New research reveals elevated toxic metal levels in residents months after the 2023 disaster. - **Source:** [Grist](https://grist.org/) - **Published:** 2026-10-16 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/f1d4cd43-303f-48c5-8668-62e742d737f5 ## Persistent Health Crisis Three years after the August 2023 Maui wildfires, residents continue to face acute health and housing challenges. Noelani Ahia, co-founder of Maui Medic Healers Hui, notes that the catastrophe remains ongoing. Despite local volunteer efforts, the community still lacks sufficient medical infrastructure to address the long-term physical impacts of the disaster. ## Elevated Toxic Levels The Maui Wildfire Exposure Study analyzed urine samples from 1,400 adults six to 18 months post-fire. Findings indicate significantly higher concentrations of toxic metals compared to pre-fire national surveys. Specifically, antimony levels were nearly 40 times higher, while manganese, barium, and arsenic concentrations also showed marked increases among the local population. ## Complex Exposure Pathways Researchers are currently investigating the origin of these contaminants, distinguishing between fire-released toxins and pre-existing environmental hazards. Because entire communities burned, the exposure environment is far more complex than traditional smoke inhalation. Understanding these sources is critical for managing health risks in urban areas facing similar wildfire-related infrastructure destruction. ## Historical Environmental Context Experts suggest that decades of plantation agriculture and land development have created a legacy of environmental contamination. Katie Kamelamela emphasizes that disasters often compound existing issues like water diversion and herbicide use. True recovery requires addressing these historical factors rather than merely rebuilding structures that previously left residents vulnerable. ## Research Funding and Scope The project received a $3.6 million grant from the National Institute of Environmental Health Sciences to deepen its investigation. Future work will determine the specific contribution of past industrial activities to current contamination levels. This data is essential for informing community health responses and understanding long-term exposure risks for survivors. ## Linking Health and Land For Native Hawaiians, recovery is deeply tied to the health of the land, or ʻāina. Researchers argue that rebuilding efforts must prioritize the ability of residents to remain in their communities and practice traditional knowledge. Funding and planning must integrate environmental care with human health to prevent widening existing disparities. ## Community Health Support The study goes beyond data collection by providing participants with individual health results and professional consultations. This approach helps residents navigate potential hazards and understand their personal exposure levels. By facilitating direct communication with health professionals, the project aims to empower the community to manage ongoing risks effectively and safely. ## Future Disaster Preparedness The Maui findings highlight that wildfires are no longer isolated, one-time events but complex, recurring threats. As climate change accelerates, the intersection of housing, tourism, and environmental legacy will continue to amplify health disparities. Policymakers must recognize these multifaceted pressures to better protect vulnerable populations during future climate-related disasters. ## Sources covering this story - https://grist.org/indigenous/long-after-the-maui-fires-toxic-metals-linger-in-residents-bodies/ — --- _Summary written by Brifing from the original reporting.
