Objective:
The objectives of this proposed research are to: 1) Measure the emission rates/fluxes of particulate matter (PM), selected volatile organic compounds (VOCs), and GHGs from open-lot cattle feedlots in Kansas and 2) Characterize the chemical nature of particulate matter emitted from commercial cattle feedlots.

Approach:
1) Measurement of the concentration profiles of PM10 and PM2.5 in a commercial feedyard - within facility and/or downwind edge of the facility. a) Quasi-continuous – tapered element oscillating microbalance (TEOMs); and b) Time-averaged – low-volume federal reference method (FRM) samplers. 2) Measurement of the concentration profiles of greenhouse gases (i.e., CO2, N2O, CH4) and selected VOCs (i.e., phenols) - within facility and/or edge-of- facility boundaries. a) Canisters – for GHGs; and b) Sorbent tubes – for selected VOCs. 3) Meteorological tower equipped with eddy covariance instrumentation to be set up within or on the downwind edge of the facility. a) 3-D sonic anemometer; b) Open-path CO2/H2O gas analyzer; and c) Temperature profile. 4) Characterization of particulates and partitioning of VOCs from PM as a function of particle size using Raman spectroscopy.
