Moscow is used as an example to discuss the problem of urban atmospheric pollution by carcinogenic N-nitrosamines. An analytical method is proposed, which is based on the use of a Russian gas chromatograph compatible with a chemiluminescence detector, that is a TEA thermal energy analyzer (USA) having some modifications to reduce the time of analysis and loss during sample pretreatment. The minimal detected concentration is 3 ng/m3 for 2-hour sampling. The method identifies and quantifies 7 volatile N-nitrosamines: N-nitrosodimethylamine (NDMA), N-nitrosodiethylamine, N-nitrosodibutylamine, N-nitrosodipropylamine, N-nitrosopiperidine, N-nitrosopyrrolidine, N-nitrosomorpholine. The pollution of the Moscow air was evaluated in the center of Moscow (30-60 ng/m3 for NDMA), in the industrial emission area (as high as several hundred ng/m3, and in the heavy traffic area (100 ng/m3 or more). It is proposed to study the working area for rubber and tire industries, to establish nitrosamine tolerances for these industries and maximum allowable discharge concentrations in the urban air and to monitor these parameters.
以莫斯科为例，讨论城市大气中致癌性N-亚硝胺的污染问题。提出了一种分析方法，该方法基于使用与化学发光检测器兼容的俄罗斯气相色谱仪，即对美国的TEA热能分析仪进行了一些改进，以减少分析时间和样品预处理过程中的损失。两小时采样的最低检测浓度为3 ng/m³。该方法可识别和定量7种挥发性N-亚硝胺：N-亚硝基二甲胺（NDMA）、N-亚硝基二乙胺、N-亚硝基二丁胺、N-亚硝基二丙胺、N-亚硝基哌啶、N-亚硝基吡咯烷、N-亚硝基吗啉。对莫斯科市中心（NDMA为30 - 60 ng/m³）、工业排放区（高达数百ng/m³）和交通繁忙区（100 ng/m³或更高）的空气污染情况进行了评估。建议对橡胶和轮胎行业的工作区域进行研究，为这些行业确定亚硝胺耐受量以及城市空气中的最大允许排放浓度，并对这些参数进行监测。
