NCIt definition : A volatile, combustible, yellow, oily liquid nitrosamine with a faint characteristic
odor that decomposes when exposed to light and emits toxic fumes of nitrogen oxides
when heated to decomposition. N-Nitrosodimethylamine is primarily used in laboratory
research to induce tumors in experimental animals. This substance may be formed during
the cooking of foods, especially cured meats and fish, that contain sodium nitrite
as a preservative, but is also found in several vegetables, cheeses, alcoholic beverages
and fruits, and as a contaminant in rubber products. Exposure to NNitrosodimethylamine
irritates the skin and eyes and damages the liver. This substance is reasonably anticipated
to be a human carcinogen. (NCI05);
