Criteria air pollutants gases threaten both the public health and the public welfare, and that greenhouse gas emissions from motor vehicles contribute to that threat. This final action has two distinct 'findings,' which are: 1) The 'Endangerment Finding' in which the Administrator found that the mix of atmospheric concentrations of six key, well-mixed greenhouse gases threatens both the public health and the public welfare of current and future generations. These six greenhouse gases are: carbon dioxide (CO), methane (CH), nitrous oxide (NO), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF). These greenhouse gases in the atmosphere constitute the "air pollution" that threatens both
Nitrous oxide system, and this may be related to its analgesic and anxiolytic properties. Nitrous oxide is 30-40 times more soluble than nitrogen. The effects of inhaling sub-anaesthetic doses of Nitrous Oxide have been known to vary, based on several factors, including settings and individual differences, however, from his discussion, Jay (2008) suggests that it has been reliably known to induce the following states and sensations: A minority of users also will present with uncontrolled vocalisations and muscular spasms. These effects generally disappear minutes after removal of the nitrous oxide source. In rats, stimulates the mesolimbic reward pathway via inducing dopamine release
