• Description:
  Bioaerosol exposures are still poorly understood and a clear cause-and-effect relationship between the exposure and adverse health outcome has not been well established. This may be partial1y due to inadequate methods utilized for exposure assessment. Traditional sampling and analysis of airborne fungi and bacteria rely on measuring intact spores and bacterial cells whereas other types of microbial propagules have not been sufficiently explored. Our previous study on fungi showed that smaller-sized fungal fragments are released together with spores from moldy surfaces (Gorny et at, 2002). In this study, we investigated the aerosolization of microbial propagules from contaminated sources in a wide size range of 0.02-10 um. Two different aerosolization mechanisms were studied: aerosolization of dry microbial particles from surfaces and microbial aerosolization from liquids. [Description provided by NIOSH]
