Dynamic air sampling of volatile organic compounds using solid phase microextraction
TL;DR: A new dynamic air sampling system was devised and evaluated in conjunction with solid phase microextraction (SPME) fiber materials for extracting odor-causing volatile organic compounds (VOCs) present in swine building environments and revealed that it was capable of detecting over 60 VOCs in a swine house.

TL;DR: In this paper, a laboratory apparatus was developed for measuring the dust-emission potential of cattle feedlot surfaces asaffected by manure surface characteristics, and the vertical action of the cattle hoof was reproduced by dropping a steel weight onto the manure surface.

Characterization of volatile organic compounds on airborne dust in a swine finishing barn
TL;DR: In this paper, three methods of extracting volatile organic compounds (VOCs) adsorbed on the airborne dust in a swine finishing building were investigated: solvent extraction using dichloromethane, solid-phase microextraction (SPME) using carboxen/======polydimethylsiloxane (CAR/PDMS) and PDMS fibers, and purge and trap.

Particulate matter emission rates from beef cattle feedlots in Kansas—Reverse dispersion modeling
Henry F. Bonifacio,Ronaldo G. Maghirang,Brent W. Auvermann,Edna B. Razote,James P. Murphy,Joseph P. Harner +5 more
TL;DR: PM10 emission rates from two large commercial cattle feedlots in Kansas were determined based on extended measurement period for PM10 concentrations and weather conditions, and reverse dispersion modeling, providing baseline information on emission rates in the Great Plains that could be used for improving emissions estimates.

Concentrations of particulate matter emitted from large cattle feedlots in Kansas.
TL;DR: This work characterized the total suspended particulates (TSP), PM10, and PM2.5 concentrations emitted from large cattle feedlots in Kansas, providing baseline information on concentrations and size distribution of particulates emitted from feedlOTS in the Great Plains.
