title: Non-volatile N-nitroso compounds in human feces.
abstract: A bacterial mutagen has been detected in ether extracts of freeze-dried feces of humans on Western diet. Several types of evidence suggest that nitroso compounds are present in human feces and the mutagen could be a nitroso compound. Ascorbic acid supplement in the diet reduces the levels of both the mutagens and nitroso compounds in the feces.
