Oligomeric amide formation in secondary organic aerosol from the photooxidation of aromatics in the presence of ammonia.
This study aims to enhance our understanding of the chemical composition and potential formation pathways of oligomeric amides in relation to the photooxidation of aromatic volatile organic compounds (VOCs) in atmospheric aerosol. Aromatic hydrocarbons (e.g., toluene, m-xylene, and ethylbenzene) undergo complex photooxidation processes that interact with NH3, leading to the formation of complex N-containing organic compounds. In this study, we successfully synthesized and characterized several oligomer amides, which were employed as standards to detect N-containing secondary organic aerosol (SOA) generated in a smog chamber under simulated atmospheric conditions. The results revealed the presence of oligomeric amides in the SOA, indicating their formation during the photooxidation process in the presence of NH3 and providing significant insights related to the chemical formation pathway of SOA.
期刊介绍：
The Science of the Total Environment is an international journal dedicated to scientific research on the environment and its interaction with humanity. It covers a wide range of disciplines and seeks to publish innovative, hypothesis-driven, and impactful research that explores the entire environment, including the atmosphere, lithosphere, hydrosphere, biosphere, and anthroposphere.
The journal's updated Aims & Scope emphasizes the importance of interdisciplinary environmental research with broad impact. Priority is given to studies that advance fundamental understanding and explore the interconnectedness of multiple environmental spheres. Field studies are preferred, while laboratory experiments must demonstrate significant methodological advancements or mechanistic insights with direct relevance to the environment.
