Polycyclic aromatic hydrocarbons (PAHs) derivatives have been considered as an emerging environmental pollutant due to their high toxicity, strong durability and difficult degradation. With the increase of automobile ownership, automobile exhaust has become one of the main contributors of the PAHs derivatives. This has received extensive attention from scholars over the worldwide. Therefore, this paper sorted out and summarized the physicochemical properties, research methods and influence factors of PAHs derivatives emissions from automobile exhaust based on the research results over the worldwide. PAH derivatives from automobile exhaust mainly included nitrated PAHs (NPAHs) and oxygenated PAHs (NPAHs), which have much higher toxicity than their parent PAHs. Their emission level was closely related to the fuel type, vehicle technical level, operating condition of vehicle engine, after-treatment technology, etc. Oxygenated fuels could reduce NPAHs, but increase OPAHs. With the increase of engine load, the PAHs derivatives emission increased. The improvement of vehicle technology and the application of after-treatment technology could reduce the PAHs derivatives emission. The purpose of this paper was to clarify the emission characteristics and influence factors of PAHs derivatives from automobile exhaust, which would provide reference for the development of automobile emission control technology and the formulation of emission regulations. %K 汽车, %K 衍生物, %K 硝基多环芳烃, %K 含氧多环芳烃, %K 尾气排放
