Short summary
The role of anthropogenic VOCs (AVOCs) for SOA formation needs to be scrutinised. The aromatic 1,3,5-trimethylbenzene (TMB) was shown to form highly oxygenated organic molecules (HOMs) in NOx-free environments, possibly contributing to new particle formation (NPF). However, formation of HOMs and particles was suppressed in the presence of NOx, while the formation of organonitrates (ONs) was increased. Thus, aromatic AVOCs may not enhance NPF in urban air masses.
