Abstract

Biological tests have shown that a significant part of the mutagenicity of organic extracts of collected airborne particulate matter is not due to polycyclic aromatic hydrocarbons (PAH). It is possible that part of these unknown compounds are transformation products of PAH. This survey focuses on the reaction of PAH in the atmosphere with other copollutants, such as nitrogen oxides, sulfur oxides, ozone and free radicals and their reaction products. Photochemically induced reactions of PAH are also included. The reactivity of particle-associated PAH is discussed in relation to the chemical composition and the physical properties of the carrier. Recommendations for future work are given.

摘要

生物学测试表明,所采集的空气中颗粒物有机提取物的致突变性很大一部分并非归因于多环芳烃(PAH)。这些未知化合物的一部分有可能是PAH的转化产物。本调查聚焦于大气中PAH与其他共污染物的反应,如氮氧化物、硫氧化物、臭氧和自由基及其反应产物。PAH的光化学诱导反应也包括在内。还讨论了与载体的化学组成和物理性质相关的颗粒结合PAH的反应活性。并给出了对未来工作的建议。
