Structural Features of Aliphatic N-Nitrosamines of 7-Azabicyclo[2.2.1]heptanes That Facilitate N−NO Bond Cleavage

, 2016
N-Nitrosamines can be considered as potential nitric oxide (NO)/nitrosonium ion (NO+) donors. However, the relation of the structures of N-nitrosamines, in particular of aliphatic N-nitrosamines, to the characteristics of release of NO or NO+ remains ...

A Survey of N-nitrosamines in Namhan River and Natural Solar Photolysis of N-nitrosamines

Journal of Environmental Analysis, Health and Toxicology
This study aimed to evaluate the impact of sunlight on the behavior of N-nitrosamines in the Jugdangcheon stream, a tributary of the Namhan River. N-nitrosamines were monitored over four occasions in 2024, and experiments were conducted to investigate their decomposition under natural sunlight, considering variables such as radiation intensity and ...
