The research community is making good progress in understanding the mechanical, biochemical, and atmospheric processes that are responsible for airborne emissions of particulate matter (PM, or dust) from open-lot livestock production, especially dairies and cattle feedyards. Recent studies in Texas, Kansas, Nebraska, Colorado, California, and Australia have expanded the available data on both emission rates and abatement measures.…

Why Study Monoslope Barns and Air Quality?
Confined cattle facilities are an increasingly common housing system in the Northern Great Plains region. Many of these facilities add organic bedding material to the pens once or twice per week. Particulate matter concentrations and emissions from these facilities have not been evaluated. …
Photometric measurement of ground-level fugitive dust emissions from open-lot animal feeding operations.
Waste to Worth home | More proceedings….
Abstract
Fugitive dust from confined livestock operations is a primary air quality issue associated with impaired visibility, nuisance odor, and other quality-of-life factors. Particulate matter has conventionally been measured using costly scientific instruments such as transmissometers, nephelometers, or tapered-element, oscillating microbalances (TEOMs). …

Abstract
Air emissions from animal feeding operations have become a growing concern for producers and their neighbors. Much work has been done to quantify emission rates; however, little information has been provided about air quality downwind from these facilities. …

Abstract
Livestock GRACEnet is a United States Department of Agriculture, Agricultural Research Service working group focused on atmospheric emissions from livestock production in the USA. The working group presently has 24 scientists from 13 locations covering the major animal production systems in the USA (dairy, beef, swine, and poultry).…
Measuring Particulate Matter (Dust) in Animal Agriculture
Particulate matter (often called dust) is made up of particles that are suspended in the air. The following materials were developed for college instructors to utilize in their classrooms when presenting about particulates and livestock or poultry farms.
Laboratory Exercises

Techniques for Determining Particle Size Distribution (PSD) of Particulate Matter
This presentation was given to the American Chemical Society in 2011 and focuses on comparisons between different techniques as well as the challenges is making these measurements.…
Mitigating Dust (Particulate Matter) Emissions from Animal Agriculture
Air emissions from animal animal feedlots are sources of many different emissions including particulate matter (dust).
The materials on this page were developed to assist educators and professors who wish to include dust and particulate emissions and their control as a topic in their classrooms or educational programs.…
Dust From Cattle Feedyards: A Case Study From Texas
When talking about air quality around animal agriculture, one of the most common neighbor complaints comes from dust (sometimes also called particulate matter). Dust is given off from cattle feedyards as animals move around on the pen surface. Although this dust usually settled out of the air relatively close to the feedlot, it can lead to nuisance issues with neighbors or nearby roadways.…
Dust (Particulate Matter) Emissions From Animal Agriculture: An Introduction
Air emissions from animal animal feedlots are sources of many different emissions including particulate matter (dust).
