1840 illustration of a man inhaling nitrous oxide, and another experiencing its effects Until at least 1863, low availability of equipment to produce the gas, combined with low usage of the gas for medical purposes, meant it was a relatively rare phenomenon that mainly happened among students at medical universities.
Nitrous oxide is a colourless gas with a faint, sweet odour. Nitrous oxide supports combustion by releasing the dipolar bonded oxygen radical, and can thus relight a glowing splint. N 2 O is inert at room temperature and has few reactions. At elevated temperatures, its reactivity increases. For example, nitrous oxide reacts with NaNH
Nitrous oxide is thought to be particularly non-toxic, though heavy long-term use can lead to a variety of serious health problems linked to the destruction of vitamin B12 and folic acid. [17] [18] Nitrous oxide "whippets" are small aerosol containers designed for charging whipped cream dispensers.
The Food and Drug Administration (FDA) regulates nitrous oxide under its Food Drug and Cosmetics Act. Although buying nitrous oxide for its intended purpose is legal, some states have outlawed the ...

The six criteria pollutants were identified based on scientific knowledge of health effects caused by the pollutants. The six criteria are the following: particulate matter (PM), nitrogen oxide NO 2, ozone O 3, sulfur dioxide SO 2, carbon monoxide (CO), and nonmethane hydrocarbons (NHMC).
