  2. NOx - Wikipedia

    en.wikipedia.org/wiki/NOx

    There are also other indirect effects of NO x that can either increase or decrease the greenhouse effect. First of all, through the reaction of NO with HO 2 · radicals, • OH radicals are recycled, which oxidize methane molecules, meaning NO x emissions can counter the effect of greenhouse gases.

  3. Greenhouse gas - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas

    This is an accepted version of this page This is the latest accepted revision, reviewed on 24 January 2025. Gas in an atmosphere with certain absorption characteristics This article is about the physical properties of greenhouse gases. For how human activities are adding to greenhouse gases, see Greenhouse gas emissions. Greenhouse gases trap some of the heat that results when sunlight heats ...

    en.wikipedia.org/wiki/Nitrous_oxide

    2 O entering the atmosphere is the result of human activity, [68] control of nitrous oxide is part of efforts to curb greenhouse gas emissions. [ 130 ] Most human caused nitrous oxide released into the atmosphere is a greenhouse gas emission from agriculture , when farmers add nitrogen-based fertilizers onto the fields, and through the ...

  5. Regulation of greenhouse gases under the Clean Air Act

    en.wikipedia.org/wiki/Regulation_of_greenhouse...

    These six greenhouse gases are: carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF 6). These greenhouse gases in the atmosphere constitute the "air pollution" that threatens both public health and welfare.

    In 2022 the IEA said that greenhouse gas emissions from gas-fired power plants had increased by nearly 3% the previous year and that more efforts were needed to reduce them. [19] As well as greenhouse gases, these power plants emit nitrogen oxides (NOx) [20] but this is less dangerous than NOx from gas appliances in houses. [21]

    Furthermore, the effectiveness of nitrous oxide as a greenhouse gas is magnified by its longer life than carbon dioxide, methane and CFC's. In essence the rate at which low level ozone is formed is determined by hydrocarbons, whilst the availability of oxides of nitrogen influences the amount it produces.

  8. Trace gas - Wikipedia

    en.wikipedia.org/wiki/Trace_gas

    A few examples of the major greenhouse gases are water, carbon dioxide, methane, nitrous oxide, ozone, and CFCs. These gases can absorb infrared radiation from the Earth's surface as it passes through the atmosphere. The most influential greenhouse gas is water vapor. It frequently occurs in high concentrations, may transition to and from an ...

  9. Peroxyacetyl nitrate - Wikipedia

    en.wikipedia.org/wiki/Peroxyacetyl_nitrate

    It is thermally unstable and decomposes into peroxyethanoyl radicals and nitrogen dioxide gas. [2] It is a lachrymatory substance, meaning that it irritates the lungs and eyes. [3] Peroxyacetyl nitrate, or PAN, is an oxidant that is more stable than ozone. Hence, it is more capable of long-range transport than ozone.
