化学、红外线和热能分析提供了证据，证明在空气颗粒物提取物中存在N-亚硝基官能团。纽约市空气中N-亚硝基的总摩尔浓度相当于多环芳烃的总浓度。由于90%的N-亚硝基化合物已被测试是致癌物质，新发现的，但未经测试的材料可能代表一个重大的环境危害。
Chemical, infrared, and thermal energy analyses have provided evidence for the presence of theN-nitroso functional group in extracts of airborne particles. The total molarN-nitroso concentrations in New York City air are equivalent to the total concentrations of polycyclic aromatic hydrocarbons. Since 90 percent of theN-nitroso compounds that have been tested are carcinogens, the newly discovered but untested materials may represent a significant environmental hazard.
