Study Methods
Which toxins were released from the fire?
Air Pollutants
We are investigating chemicals (VOCs), metals, and particles (PM2.5 and PM1.0) in indoor and outdoor air.
Debris
We are investigating the distribution and transport of fire debris in surface water and stormwater.
Water Pollutants
We are investigating chemicals (VOCs) and metals in tap water.
Ash
We are investigating data briefs investigating contents of settled ash in and around homes.
How are we measuring them?
Mobile Monitoring
Using our mobile vans to take measurements of chemicals (VOCs), metals, and particulate pollution (PM2.5 and PM1.0) in and around affected areas.
Home Studies
Measuring air/water/dust/soil in homes in and around burn zones.
Emissions Modeling
Modeling exposures from fire emissions based on the distribution of different fuel stocks in urban and woodland areas.
Smoke Composition
Characterizing the composition of smoke residues and settled ash in communities downwind.
Surface Water Flow and Soil Testing
Mapping the transport of fire debris in surface water and taking soil samples of affected areas.
Firefighters
Monitoring exposures to professional and resident firefighters.
