Particulate matter from open lot dairies and cattle feeding: recent developments

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.…

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). …

Why Is It Important for Industry and Regulators to Work Together?

The community in the Yakima Region of Washington State has raised concerns over the potential adverse effects of air emissions from dairy operations. To address these concerns, the Yakima Regional Clean Air Agency (YRCAA) proposed a policy process in October 2010 to control and mitigate emissions through implementation of site-specific best management practices (BMPs) on dairy operations.…

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.…
