Finding F-1586

“We found a slow decrease in VOC mixing ratios over the course of roughly 5 weeks starting 10 days after the fire, and those levels decreased to ∼20% of the initial indoor value on average.”

Volatile Organic Compounds Inside Homes Impacted by Smoke from the Marshall Fire Published as part of ACS ES&T Air special issue “Wildland Fires: Emissions, Chemistry, Contamination, (2025). ACS EST Air. Page 1. CKB 1135

Structure

Source: Wildfire smoke
Factor: Volatile organic compounds (VOCs)
Method: Mass spectrometry
Setting: home, US
Study design: field measurement campaign in homes affected by a wildland-urban interface fire: volatile organic compounds measured indoors by proton-transfer-reaction time-of-flight mass spectrometry over the weeks following the fire, with mitigation tests using activated-carbon air cleaners and window opening (class 4)
Effect: other 20
Caveat: approximately, and on average across the compounds, over roughly 5 weeks starting 10 days after the fire
