title: [N-nitrososarcosine formation from predecessors in the body].
abstract: A method has been developed for isolation and analysis of the non-volatile carcinogen N-nitrososarcosine in different media. It has been found that in aqueous solution and gastric juice of the dog, N-nitrososarcozine is formed in an acid medium, with maximum yield being attained at pH 3 and at an equal molar ratio of the precursors. Endogenous formation of the carcinogen in the rat stomach has been studied.
