This project will determine the age-adjusted prevalence of airways obstruction in Federal wildland firefighters, as well as examine predictors of decreased lung function in these individuals at baseline and of short-term changes in lung function (pre-post fire), adjusting for competing and confounding factors. Predictors of airways inflammation and FEV1 and FVC as well as the relationship between these two measures will be examined. Additionally, we will determine the size distribution of particulate matter in wildfire smoke and ascertain the free radical concentration in the products of combustion. Finally, we will size-classify the smoke aerosol ranging from the ultracoarse (> 10 µm) through the ultrafine (< 100 nm) fractions.
