Ammonia emissions from livestock and poultry
Best insight from top research papers
Ammonia emissions from livestock and poultry have significant impacts on the environment, air quality, and human health. The intensive rearing of poultry and pigs in modern intensive agriculture has led to the implementation of protocols and regulations to reduce these emissions . Livestock, including poultry, is a major contributor to global ammonia emissions, with about 85% of anthropogenic emissions related to food and feed production . The ammonia emission levels and distribution characteristics vary depending on factors such as temperature, ventilation, and manure management . Agricultural activities, including livestock production, contribute to global ammonia emissions, with cattle, rice, maize, and wheat being major sources . Climate change is expected to increase ammonia emissions from poultry farming due to the influence of meteorological factors . Overall, reducing ammonia emissions from livestock and poultry is crucial for mitigating their negative impacts on the environment and human health.

How does atmospheric ammonia affect the reproductive cycle of laying hens?5 answersAtmospheric ammonia exposure can significantly impact the reproductive cycle of laying hens. High levels of atmospheric ammonia have been linked to stress responses in hens, leading to increased serum corticosterone levels, decreased egg production, and alterations in hormone profiles such as progesterone and estradiol-17. Additionally, ammonia-induced damage in ducks has been reported, highlighting the toxic effects of ammonia exposure on poultry. Furthermore, studies on NH3 emissions from different types of laying hen houses showed that environmental factors like temperature and ventilation rates can influence NH3 levels, which in turn affect the reproductive performance of hens. These findings underscore the detrimental effects of atmospheric ammonia on the reproductive health and productivity of laying hens.
What is the evidence to show that concentrations of ammonia higher than 10 ppm is aversive to chickens?4 answersEvidence from various studies indicates that concentrations of ammonia higher than 10 ppm are aversive to chickens, affecting their health, behavior, and performance. Research by R. N. Sa et al. demonstrated that ammonia concentrations exceeding 50 ppm reduced average daily feed intake and weight gain in broilers, with significant alterations in body fat distribution and lipid metabolism at 75 ppm, suggesting adverse effects on production performance and physiological health at concentrations well above 10 ppm. Guan-Lian Wang et al. found that exposure to ammonia levels of 25 and 35 ppm significantly affected pulmonary microflora, inflammatory cytokines, and neurotransmitters in broilers, indicating a detrimental impact on respiratory health and potentially the lung-brain axis.
While Morgan D. Hayes et al. and Angela R. Green et al. explored aversion in laying hens and pullets to 25 ppm ammonia without conclusive evidence of aversion, the trends suggested a potential for aversion that warrants further investigation. Christopher M. Wathes et al. conducted choice tests with domestic fowl, showing a significant preference for fresh air over ammoniated atmospheres and a decline in visit duration and frequency with increasing ammonia concentrations, indicating aversion to even lower concentrations than 25 ppm. This is supported by another review by Wathes et al., which suggests that animals avoid ammonia concentrations above 10 ppm based on preference studies, proposing that current guidelines for ammonia exposure may be too high.
Furthermore, H.A. Olanrewaju et al. reported that ammonia concentrations at 25 and 50 ppm induced eye lesions in broiler chickens, with the severity increasing with concentration, highlighting direct adverse effects on ocular health. Sadia Naseem and Annie J. King emphasized that less than 10 ppm is the ideal limit for ammonia exposure, indicating that levels above this threshold could be harmful. I.U. Sheikh et al. and D. M. Miles et al. both noted adverse effects on health and welfare, including reduced performance and ocular abnormalities, at ammonia concentrations exceeding 25 ppm, further supporting the aversion and detrimental impact of higher ammonia levels on chickens. Collectively, these studies provide compelling evidence that ammonia concentrations higher than 10 ppm are aversive to chickens, affecting their health, behavior, and overall well-being.
Ammonia used as fertilizer5 answersAmmonia is widely used as a fertilizer in the processing industry. It is an essential compound for modern society, supporting fertilizer production and chemical manufacturing. Ammonia can be produced through different processes, using various raw materials, with some methods being more environmentally friendly than others. The production of ammonia from natural gas is a common method, where natural gas is steam reformed to produce hydrogen, which is then converted into ammonia. Biological approaches have also been developed for sustainable ammonia production, such as nitrogen fixation by nitrogenase and ammonia production from food waste using microorganisms. The use of ammonia as a fertilizer requires special attention to ensure the safety of storage and handling.
Ammonia causing Water pollution5 answersAmmonia is a nitrogenous compound that can cause water pollution, leading to eutrophication and deterioration of water quality. It is discharged into natural water bodies by industrial and agricultural sectors. Ammonia pollution can also occur through accidents, such as ammonia pipe leaks, which can result in air and water pollution. Nitrogenous pollutants, including ammonia, can have toxic effects in water, stimulate eutrophication, and interfere with purification processes. Ammonia emissions primarily originate from agricultural sources and contribute to a wide range of environmental problems, including acid deposition, excess nutrient deposition, and climate change. Despite its harmful effects, ammonia emissions have not been subject to stringent control policies, unlike other pollutants. Therefore, it is important to identify emission sources and policy options to reduce the harmful environmental effects of ammonia.
What is impct Ammonia on Air?5 answersAmmonia has various impacts on air quality. It is a major pollutant that can be harmful to human health, causing irritations to the skin, eyes, respiratory tract, and lungs. Ammonia is also a key transboundary air pollutant that contributes to nitrogen and acidity impacts on terrestrial ecosystems. Additionally, ammonia is a component of particulate matter, which poses risks to human health. The presence of ammonia in the air can have both short-term and long-term effects. Short-term exposure can lead to irritations and burns, but these can be treated and recovered from. Long-term exposure to ammonia may not cause specific carcinogenic diseases, but it can result in permanent burn injuries, respiratory issues, and even brain-related diseases in some cases. Overall, ammonia in the air has significant implications for both human health and the environment.
What are the effects of ammonia on air quality?5 answersAmmonia (NH3) has significant effects on air quality. Reactions between NH3 and organic compounds in aerosol particles can form organic products that are less basic than NH3, leading to reduced efficiency in neutralizing nitric and sulfuric acids. NH3 emissions contribute to fine particulate matter (PM2.5) pollution, and reducing NH3 emissions can lead to reductions in PM2.5 concentrations and associated premature human mortality. NH3 concentrations in urban areas can be influenced by air masses from ammonia-rich areas and industrial emissions, and NH3 can contribute to the formation of sulfate-nitrate-ammonium (SNA) aerosols. NH3 emissions from agriculture play a role in the formation of airborne particulate matter, and exposure to particulate matter air pollution has been linked to human mortality. Surface exchange between the atmosphere and biosphere is an important part of the ammonia cycle, and modeling techniques are being developed to better understand NH3 fluxes from croplands.
