Are all nitrosamines carcinogenic?
The recent discovery of nitrosamine impurities in several marketed pharmaceuticals has increased interest in their mutagenic and carcinogenic potential. It was found that 18% of nitrosamines were considered non-carcinogenic.
What does nitrosamines do to your body?

How are Nitrosamines formed from amines and nitroso acid?
(nī-trōs’am-ēnz), Amines substituted by a nitroso (NO) group, usually on a nitrogen atom, to yield N-nitrosamines; can be formed by direct combination of an amine and nitrous acid (can be formed from nitrites in the acidic gastric juice); some are mutagenic and/or carcinogenic.
How are nitrosamines used as disinfection by-products?
Nitrosamines may be formed as disinfection by-products when dichloramine in water reacts with available organic matter of either natural or man-made origins.
