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 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.
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
The dangerous practice is a means of getting high via inhaling hydrocarbons by misusing a variety of legal products, including permanent markers, aerosol deodorant, nail polish, metallic paint ...
An "incident" of chemical food contamination may be defined as an episodic occurrence of adverse health effects in humans (or animals that might be consumed by humans) following high exposure to particular chemicals, or instances where episodically high concentrations of chemical hazards were detected in the food chain and traced back to a particular event.
The Center for Disease Control and Prevention estimates that every year 48 million Americans, or roughly one in six people, get sick from foodborne illnesses, and about 3,000 cases each year are ...

The effect of inhaling irritant gases depends on the extent and duration of exposure and on the specific agent [22] [23] [24] Chlorine, phosgene, sulfur dioxide, hydrogen chloride, hydrogen sulfide, nitrogen dioxide, ozone, and ammonia are among the most important irritant gases.
