In the production of food Nitrosamines are formed from the joining of amines and a nitrosating agent. Especially in the process of direct-fire drying, nitrogen from the air combines with amines to form volatile Nitrosamines. Ascorbic acid and sulfur dioxide are often used to prevent the formation of Nitrosamines but usually only limit it. Not much is known about these volatile Nitrosamines but that they occur in a variety of foods including fish, meats, dairy products, and more. Sometimes however there is not a detectable amount of Nitrosamines in some samples or very little. While investigators assure that the intake of these Nitrosamines is only 1 microgram per person daily, the dangers still exist.<ref name=mig> Sahelian, Ray.

Unfortunately Nitrosamines can also sometimes be found in drinking water. They are often found in waste water treated with chlorine based disinfectants. The US average of Nitrosamines infested treated water is 9%. As high as 34.5% of the treated water in Texas contains Nitrosamines.

According to Professor William Mitch's tests, indoor pools contain nearly 6 times more Nitrosamines than outdoor pools. This leads to his conclusion that UV rays from the sun help kill much of the Nitrosamine molecules. In addition his tests also show that in hot tubs the high temperature promotes Nitrosamines to grow 10 times greater than even indoor pools.<ref name=yale> Muller, Brent.
