Abstract. Anthropogenic volatile organic compounds (AVOCs) often dominate the urban atmosphere and consist to a large degree of aromatic hydrocarbons (ArHCs), such as benzene, toluene, xylenes, trimethylbenzenes, e.g., from handling combustion fuels. These are important precursors for formation secondary aerosol. Here we show that oxidation aromatics with OH leads subsequent autoxidation chain reaction forming highly oxygenated molecules (HOMs) an O : C ratio up 1.09. This is exemplified...
