A Pilot Study: The UNC Passive Aerosol Sampler in a Working Environment

ConclusionsParticle mass concentrations appear to be underestimated by the UNC sampler compared to impactors, more so for PM2.5 than for PM10. CT may be preferred as a collection surface because the blank values were lower and less variable than for PC. Future validations in the working environment should include respirable dust sampling.
