This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A total of 110 samples of volatile organic compounds (VOCs) were collected and analyzed in a field study to characterize such compounds emitted at six swine facilities in Eastern North Carolina between April 2002 and March 2003 as part of the Project OPEN (Odors, Pathogens, and Emissions of Nitrogen). Two baseline sites employed conventional lagoon and field spray technologies while four sites utilized various alternative 'Environmentally Superior Technologies' (ESTs) in an effort to substantially reduce gaseous compound emissions, odor, and pathogens from these swine facilities. More than 200 compounds, including various paraffins, alkynes, aromatics, esters, ethers, monoterpenes, alcohols, aldehydes, ketones, monoterpenes, halogenated hydrocarbons, phenols, and sulfides were identified and quantified by Gas Chromatographic/Flame Ionization Detection (GC/FID) analysis as well as confirmed and/or verified by Gas Chromatographic/Mass Spectrometry (GC/MS). GC/MS analysis of three particularly complex samples collected at one site assisted in providing identification and retention times for more than 20 sulfur type volatile organic compounds (VOCs) including methyl mercaptan, dimethyl sulfide, dimethyl disulfide, and dimethyl trisulfide as well as many other VOCs. Carbonyl sulfide and carbon disulfide were positively identified by GC/MS analysis but were not identified by GC/FID due to their particular compound characteristics. The results of these samples were subsequently used as a source fingerprint to identify and/or verify these compounds in all other samples collected. Overall, the highest VOC concentration levels measured at each of the sites were in close proximity to the hog barns. The total measured VOCs at the hog barns were typically dominated by ethanol, methanol, acetaldehyde, and acetone. The combined overall contribution of these compounds in relation to total measured VOCs generally ranged from 46-94%. The highest concentration levels of both dimethyl.
Book Synopsis Air Quality and Livestock Farming by : Thomas Banhazi
Download or read book Air Quality and Livestock Farming written by Thomas Banhazi and published by CRC Press. This book was released on 2018-06-13 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Air quality has a direct influence on health, welfare and production performance of livestock as the high concentrations of noxious gases, dust and airborne microorganisms are likely to reduce production efficiency and the general welfare of farm animals. Long term exposure to particulates in livestock buildings might also affect the respiratory health of farm workers. Dust in animal buildings contains many biologically active substances such as bacteria, fungi, endotoxins and residues of antibiotics (as a result of veterinary treatments) that are suspected to be hazardous to human health. Furthermore, air pollutants emitted from livestock buildings can reduce air, water and soil quality and can potentially undermine the health of nearby residents. Airborne emissions include ammonia, methane, nitrous oxide, particulates like dust and microorganisms. In addition, other potentially harmful substances such as heavy metals, antibiotic residues and components of disinfectants might be also emitted from livestock building that are potentially damaging to ecosystems. In this book, key aspects of agricultural air quality, such as monitoring, managing and reducing airborne pollutants in and around livestock facilities are reviewed. Features: addressing the raising awareness of the importance of optimal health and welfare for lifestock species with contributions from international specialists and researchers providing up-to-date information for professionals involved in modern animal producti This book will be useful for farming professionals, academics, students, policy makers, business leaders, regulatory bodies and agricultural consultants.

Download or read book Air Emissions from Animal Feeding Operations written by National Research Council and published by National Academies Press. This book was released on 2003-04-07 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Air Emissions from Animal Feeding Operations: Current Knowledge, Future Needs discusses the need for the U.S. Environmental Protection Agency to implement a new method for estimating the amount of ammonia, nitrous oxide, methane, and other pollutants emitted from livestock and poultry farms, and for determining how these emissions are dispersed in the atmosphere. The committee calls for the EPA and the U.S. Department of Agriculture to establish a joint council to coordinate and oversee short - and long-term research to estimate emissions from animal feeding operations accurately and to develop mitigation strategies. Their recommendation was for the joint council to focus its efforts first on those pollutants that pose the greatest risk to the environment and public health.

Book Synopsis A Framework for Assessing Effects of the Food System by : National Research Council
Download or read book A Framework for Assessing Effects of the Food System written by National Research Council and published by National Academies Press. This book was released on 2015-06-17 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: How we produce and consume food has a bigger impact on Americans' well-being than any other human activity. The food industry is the largest sector of our economy; food touches everything from our health to the environment, climate change, economic inequality, and the federal budget. From the earliest developments of agriculture, a major goal has been to attain sufficient foods that provide the energy and the nutrients needed for a healthy, active life. Over time, food production, processing, marketing, and consumption have evolved and become highly complex. The challenges of improving the food system in the 21st century will require systemic approaches that take full account of social, economic, ecological, and evolutionary factors. Policy or business interventions involving a segment of the food system often have consequences beyond the original issue the intervention was meant to address. A Framework for Assessing Effects of the Food System develops an analytical framework for assessing effects associated with the ways in which food is grown, processed, distributed, marketed, retailed, and consumed in the United States. The framework will allow users to recognize effects across the full food system, consider all domains and dimensions of effects, account for systems dynamics and complexities, and choose appropriate methods for analysis. This report provides example applications of the framework based on complex questions that are currently under debate: consumption of a healthy and safe diet, food security, animal welfare, and preserving the environment and its resources. A Framework for Assessing Effects of the Food System describes the U.S. food system and provides a brief history of its evolution into the current system. This report identifies some of the real and potential implications of the current system in terms of its health, environmental, and socioeconomic effects along with a sense for the complexities of the system, potential metrics, and some of the data needs that are required to assess the effects. The overview of the food system and the framework described in this report will be an essential resource for decision makers, researchers, and others to examine the possible impacts of alternative policies or agricultural or food processing practices.
Book Synopsis Pigs, Profits, and Rural Communities by : Kendall M. Thu
Download or read book Pigs, Profits, and Rural Communities written by Kendall M. Thu and published by State University of New York Press. This book was released on 1998-07-23 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book illuminates the processes and consequences of agricultural industrialization, particularly within the swine production industry, for the social, economic, human, environmental, and political health of the rural United States. Contributors come from widely divergent backgrounds including a former U.S. senator, farmers, a veterinarian, a medical psychologist, an agricultural economist, a biological ecologist, a farm organization president, and anthropologists. Set within the theoretical framework of Walter Goldschmidt's research on the community consequences of industrialized food production, these contributions show that the increasing divergence of ownership has real human costs that continue to be ignored by economic developers and policymakers.
