2006 journal article

Comparison of measured total suspended particulate matter concentrations using tapered element oscillating microbalance and a total suspended particulate sampler

JOURNAL OF THE AIR & WASTE MANAGEMENT ASSOCIATION, 56(3), 261–270.

By: S. Jerez*, Y. Zhang *, J. McClure*, L. Jacobson*, A. Heber*, S. Hoff*, J. Koziel *, D. Beasley n

MeSH headings : Air Pollutants / analysis; Animal Husbandry; Animals; Chickens; Dust / analysis; Environmental Monitoring / instrumentation; Environmental Monitoring / methods; Humidity; Reproducibility of Results; Swine; Temperature; United States; Ventilation
TL;DR: A comparison of the concentration of the total suspended particulate (TSP) matter measured by the tapered element oscillating microbalance (TEOM) monitor and the isokinetic TSP samplers developed at the University of Illinois was carried out in several types of confinement livestock buildings; the model that best describes the relationship between the two methods was site specific.
