A significant source of greenhouse gas (GHG) emissions comes from the manufacture of synthetic nitrogen (N) fertilizers consumed in the production of animal feed. States, the use of N fertilizer in livestock production is estimated to account for about 10% of the total GHG emissions from animal production.
U.S. livestock sector, N fertilization accounts for more than half of total N emissions, and the majority of these emissions come from synthetic N. Synthetic N is produced in a number of ways, including by using ammonium nitrate (NH4NO3) as a feedstock, by converting N to N-nitroso compounds (NOx), or by combining N with other compounds such as ammonia, hydrogen sulfide (H2S), and sulfur dioxide (SO2).
N has been shown to have a wide range of adverse effects on the environment. For example, it is a major contributor to the formation of nitrous oxide, which contributes to acid rain and smog, as well as to global warming.

What are 3 types of greenhouse gases?
The main gases responsible for the greenhouse effect are carbon dioxide, methane, nitrous oxide, and water vapor, which all occur naturally. Fluorine is one of the most important greenhouse gases. It is a colorless, odorless gas with a very short half-life, which means that it stays in the air for only a short time before it is no longer detectable by the human eye.
Fluoride is also a potent greenhouse gas because it traps heat and increases the Earth’s surface temperature. In addition, it has been shown to have a negative effect on the ozone layer, a protective layer of ozone that protects us from harmful ultraviolet radiation.
What are synthetic fluorinated gases?
(PFCs) and sulfur hexafluoride (SF6) are synthetic, powerful greenhouse gases that are emitted from a variety of industrial processes. SF6 are ozone-depleting substances that are not as effective as fluoroinated gases. States, the use of these gases is regulated by the Environmental Protection Agency (EPA) under the Clean Air Act (CAA).
CAA regulates the production, use, disposal, and disposal of HFC gases, as well as the manufacture, distribution and sale of refrigerants, aerosols, solvents and other chemicals used in refrigeration, air conditioning, heating and air-conditioning (A/C) systems. These laws include the Hazardous Substances Control Act of 1970 (HSCA), the Federal Food, Drug and Cosmetic Act and the Occupational Safety and Health Act.
What is a green house gas example?
The most important greenhouse gases are carbon dioxide, methane, and water vapour. The amount of carbon dioxide released by human activity is the main driver of global warming, but other factors also play a role. For example, the burning of fossil fuels such as coal and oil releases methane as a by-product.
Methane is a potent greenhouse gas, trapping up to 40 times more heat than CO2 over a 100-year time period. It is also a major contributor to global sea level rise, which is expected to accelerate as the planet warms. The melting of the Greenland and Antarctic ice sheets has also contributed to the rise in sea levels.
What is synthetic fertilizer?
Synthetic fertilizer is derived from chemicals such as ammonia, natural gas, atmospheric nitrogen, phosphate minerals, and sulfur. A manufacturing plant is used to make a number of different products. Fertilizers are used in a wide variety of applications.
What is artificial nitrogen?
Synthetic nitrogen, used extensively in conventional fertilizers, helps farmers produce higher yields to feed a growing world population. Nitrogen can be lost from the farm fields if it is not fully utilized by the growing plants.
“Nitrogen is a critical nutrient for agriculture, but it is also a pollutant that can have a negative impact on human health and the environment,” said lead study author and UC Davis professor of biochemistry and biophysics, Dr. Robert J. Kopp, Ph.D.
What is fluorinated greenhouse gas?
The f-gases are a family of gases with fluorine. The use of greenhouse gases has increased dramatically in recent decades. The use of fluorinated gases has led to a significant increase in global greenhouse gas emissions. States, for example, the amount of carbon dioxide (CO2) emitted from the burning of fossil fuels has more than doubled since the mid-1970s, from about 1.2 billion metric tons to about 3.6 billion.
Is ozone a greenhouse gas?
The ozone layer protects us from the sun’s harmful ultraviolet rays, which cause skin cancer and other diseases. Ozone also protects our lungs from harmful ozone-depleting substances, such as chlorofluorocarbons (CFCs), which are used in refrigerators, air conditioners, and aerosol cans.
Is CFC a fluorinated gas?
HCFCs, halons and other greenhouse gases have high global warming potential. Substances such as chlorofluorocarbons which deplete the ozone layer have long been subject to an international phase-down on their use.
States, for example, the Environmental Protection Agency (EPA) has proposed a rule that would phase out the production of the most widely used refrigerants, including refrigerant A, which is used in refrigerators, freezers and air conditioners. The proposed rule is expected to be finalized by the end of this year, and it is likely that it will be challenged in court.
U.K., the government is also considering a proposal to phase down the manufacture of halogenated hydrocarbons, or HHCs, a group of chemicals that are used to make halon-based air fresheners, dehumidifiers and deodorants. These chemicals have been linked to a wide range of health problems including cancer, birth defects, asthma and other respiratory problems.
Is CO2 a greenhouse gas?
The insulation that keeps the planet warm is formed by these gases. Greenhouse gas levels are measured in parts per million (ppm). For example, a measurement of 0.1 ppm is considered to be “safe” for humans to breathe. (EPA) has set a limit of 400 ppm as the safe limit for human exposure to greenhouse gases.
