Abstract

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.

水生生态系统中的亚硝胺：来源，形成，毒性，环境风险（综述）1.水体的结构，性质，进入和形成的方式

摘要

由于自然过程和人为活动所导致的氮化合物对天然水的饱和作用，因此出现了研究其在水圈和水生生物中迁移，转化方式的问题。环境中氮转化的方法之一是亚硝胺的形成，亚硝胺是具有致癌，诱变和致畸特性并对生物具有毒性作用的有毒生物或生物群。进入水体的含氮化合物（亚硝胺的前体）的主要来源是农业，工业和市政废水。本文分析了在水生环境和生物体或生物区系中亚硝胺的合成方法，这些化合物的主要分析方法，它们在水圈中的分布和转化，
