Wearable Devices Track Postwildfire Indoor Exposures

Researchers led by Krystal Pollitt at Yale deployed silicone wearable passive air samplers to 30 Los Angeles-area homes between February and April 2025 to profile chemical exposures following the LA wildfires. They found combustion-related volatile and semivolatile chemicals persisted indoors for months, with indoor levels often exceeding outdoor concentrations, informing remediation and biomonitoring efforts.
Scoring Rationale
Strong, timely academic field study demonstrating persistent indoor exposures; limited direct clinical outcome linkage and biomarker calibration remain.
