Determination of dietary exposure and extraction efficiency of nitrosamine from cooked meat
Meat products are claimed to be a source of carcinogenic nitrosamines (NAs) exposure in food. In this study, dietary exposure of six nitrosamines: N-nitrosodimethylamine (NDMA), N-nitrosodiethylamine (NDEA), N-nitrosopyrrolidine (NPYR), N ...

Permitted daily exposure limits for noteworthy N‐nitrosamines
A genotoxic carcinogen, N‐nitrosodimethylamine (NDMA), was detected as a synthesis impurity in some valsartan drugs in 2018, and other N‐nitrosamines, such as N‐nitrosodiethylamine (NDEA), were later detected in other sartan products.

Use of the bacterial reverse mutation assay to predict carcinogenicity of N-nitrosamines.
Under ICH M7, impurities are assessed using the bacterial reverse mutation assay (i.e., Ames test) when predicted positive using in silico methodologies followed by expert review.
