Occupational Safety

Air Sampler for Collecting Airborne Pollutants in a Micro Centrifuge 
Tube for Molecular Analysis

    Occupational exposure to small particles, such as fungal spores, 
bacteria, dust, etc., is of concern in a number of places that exhibit 
air quality problems, for example, school buildings and agricultural 
settings. The conventional approach for assessing human exposure to 
bioaerosols has been to take samples using filters, impingers, or 
impactors and then perform laboratory analyses, which could be directly 
counting the organisms or indirectly counting their colony-forming 
units. While these methods provide reasonably adequate assessment in 
bioaerosol concentration, they are time-consuming and sometimes take 
days or even weeks to conduct the analysis. In addition, although the 
health consequence is evident, there has been difficulty in 
establishing exposure-response relationship because of the poor 
correlation between measured biomass and recorded health effect. Recent 
attention paid to indoor air quality, biological warfare and terrorist 
attacks has revealed a need for highly specific and sensitive 
techniques, such as immunoassays and polymerase chain reactions (PCR), 
for detecting a variety of air pollutants. However, there is a lack of 
sampling devices that could provide adequate sampling of airborne 
pollutants and match these advanced analytical techniques.
    Researchers at NIOSH have evaluated sampling techniques matched to 
the analytical procedures used in PCR, immunoassays, and other 
procedures, and developed a personal sampler for collecting airborne 
pollutants. Preliminary data have demonstrated an excellent aspiration 
and collection efficiency for the sampler. It is the intent that use of 
this sampler would solve the technical compatibility problem between 
sampling and analyzing as well as allow sample analysis without the 
need for sample extraction which is required by most current air 
sampling methods. In turn, the whole scheme of sampling and analysis 
would help enhance the assessment of exposure to airborne pollutants.
