The surge of urban wildfires across Los Angeles County in early January 2025 released hazardous air pollutants and ash, raising environmental concerns and potential health risks associated with toxic particulate inhalation among workers in post-wildfire settings. To test the cytotoxicity of nanoparticles in wildfire ash, we designed an in vitro model to examine the inflammatory responses and cell death of human bronchial epithelial cells.
