Additional information
Ultrastructural changes in liver tissue of mice fed nitrosamine precursors, 1000 ppm of the test substance and 2000 ppm nitrite, were observed. 6 months of chronic treatment with the combination resulted in swelling of mitochondria and distension of smooth ER, and after 12 months, an increased incidence of nodules, necrotic foci and hepatoma was found. Degenerative or neoplastic liver changes were not found in controls or in animals of treatment groups receiving a diet supplemented with soybean or ascorbic acid. The effect of the test substance, in the absence of exogenous nitrite, was not investigated.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
