Due to the saturation of natural waters with nitrogen compounds resulting from natural processes and anthropogenic activities, the problem arises of studying the ways of their migration, transformation in the hydrosphere and in aquatic biota. One of the ways of nitrogen transformation in the environment is the formation of nitrosamines—toxic organisms or biota that exhibit carcinogenic, mutagenic and teratogenic properties and have a toxic effect on living beings. The main sources of nitrogen-containing compounds, precursors of nitrosamines, into waterbodies are agricultural, industrial and municipal wastewater. The present paper analyses the ways of synthesis of nitrosamines in the aquatic environment and in living organisms or biota, the main methods of analysis of these compounds, their distribution and transformation in hydrosphere, as well as the ways of decrease in their concentrations and modern techniques for removal of nitrosamines from aquatic ecosystems.
