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

ABSTRACT:

Objectives

Dust is generally sampled on a filter using air pumps, but passive sampling could be a cost-effective alternative. One promising passive sampler is the University of North Carolina passive aerosol sampler (UNC sampler). The aim of this study is to characterize and compare the UNC sampler's performance with PM10 and PM2.5 impactors in a working environment.

Methods

Area sampling was carried out at different mining locations using UNC samplers in parallel with PM2.5 and PM10 impactors. Two different collection surfaces, polycarbonate (PC) and carbon tabs (CT), were employed for the UNC sampling. Sampling was carried out for 4-25 hours.

Results

The UNC samplers underestimated the concentrations compared to PM10 and PM2.5 impactor data. At the location with the
