“…19 Overall mean net mass concentrations of PM 2.5 , PM 10 , and TSP at KS1 were 25, 76, and 201 mg/m 3 , respectively. For KS2, only two cases of 24-hr net mass concentrations were obtained; the upwind TSP data were not available because of TSP sampler malfunction.…”

“…This finding was consistent with the MOUDI results, in which the mean GMD was 13.0 mm and consistent with previous studies that reported GMD ranging from 9.5 to 16.0 mm. 18,19 In comparison, PM measurements in urban areas showed the PM 2.5 /PM 10 , PM 2.5 /TSP, and PM 10 /TSP ratios typically run higher with average of 0.54, 0.30, and 0.50, respectively. 31,32 Studies in Swiss and Asian regions also Note: *Row means followed by the same letter are not significantly different at the 0.05 level of significance.…”

“…These values were within the ranges of published values for cattle feedlots. Sweeten et al 19 reported mean downwind concentrations of 700 mg/m 3 (range of 97-1685 mg/m The primary and secondary 24-hr national ambient air quality standards (NAAQS) for PM 10 is 150 mg/m 3 and is not exceeded more than once per year on average over a 3-yr period. The PM 2.5 24-hr concentration must not exceed 35 mg/m 3 over a 3-yr period.…”

“…[18][19][20] Based on cattle feedlots in Texas, the mean net TSP was 412 mg/m 3 (15 events measured seasonally in 1987), with PM 10 concentrations of 19% to 40% of TSP. 18,19 In a related study, Purdy et al 20 reported that the downwind PM 2.5 /PM 10 ratio was close to 10%. From the limited data available, dust from cattle appears to be large with over half larger than PM 10.…”

Particulate matter (PM) emitted from cattle feedlots are thought to affect air quality in rural communities, yet little is known about factors controlling their emissions. The concentrations of PM (i.e., PM 2.5 , PM 10 , and total suspended particulates or TSP) upwind and downwind at two large cattle feedlots (KS1, KS2) in Kansas were measured with gravimetric samplers from May 2006 to October 2009 (at KS1) and from September 2007 to April 2008 (at KS2). The mean downwind and net (i.e., downwind À upwind) mass concentrations of PM 2.5 , PM 10 , and TSP varied seasonally, indicating the need for multiple-day, seasonal sampling. The downwind and net concentrations were closely related to the moisture content of the pen surface. The PM 2.5 /PM 10 and PM 2.5 /TSP ratios at the downwind sampling location were also related to the moisture content of the pen surface, humidity, and temperature. Measurement of the particle size distribution downwind of the feedlot with a cascade impactor showed geometric mean diameter ranging from 7 to 18 mm, indicating that particles that were emitted from the feedlots were generally large in size.

“…Direct measurements have been converted to volume as described above. Since we do not have a direct measurement of particle density, we considered converting volume to mass three ways, using the density of airborne dust, 1.71 g cm −3 , compacted feedlot soil, 2.65 g cm −3 , and water, 1.0 g cm −3 (Sweeten et al, 1998;Smettem, 2006). We consider the density of dust to be the best estimate, and soil and water as upper and lower limits to the actual density, respectively.…”

High concentrations of coarse particles emitted from a cattle feeding operation

Abstract. Housing roughly 10 million head of cattle in the United States alone, open air cattle feedlots represent a significant but poorly constrained source of atmospheric particles. Here we present a comprehensive characterization of physical and chemical properties of particles emitted from a large representative cattle feedlot in the Southwest United States. In the summer of 2008, measurements and samplings were conducted at the upwind and downwind edges of the facility. A series of far-field measurements and samplings was also conducted 3.5 km north of the facility. Two instruments, a GRIMM Sequential Mobility Particle Sizer (SMPS) and a GRIMM Portable Aerosol Spectrometer (PAS), were used to measure particle size distributions over the range of 0.01 to 25 µm diameter. Raman microspectroscopy was used to determine the chemical composition of particles on a single particle basis. Volume size distributions of dust were dominated by coarse mode particles. Twenty-four hour averaged concentrations of PM 10 (particulate matter with a diameter of 10 µm or less) were as high as 1200 µg m −3 during the campaign. The primary constituents of the particulate matter were carbonaceous materials, such as humic acid, water soluble organics, and less soluble fatty acids, including stearic acid and tristearin. A significant fraction of the organic particles was present in internal mixtures with salts. Basic characteristics such as size distribution and composition of agricultural aerosols were found to be different than the properties of those found in urban and semi-urban aerosols. Failing to account for such differences may lead to errors in estimates of aerosol effects on local air quality, visibility, and public health.
