TL;DR: Results from photooxidation of aromatic compounds in a reaction chamber show that a substantial fraction of the organic aerosol mass is composed of polymers, which results in a lower volatility of this secondaryorganic aerosol and a higher aerosol yield than a model using vapor pressures of individual organic species would predict.

TL;DR: In this article, the authors proposed that the interaction between NO2 and soot particles may account for the high concentrations of HNO2 in air masses where combustion sources contribute to air pollution by soot and NOx emissions.

TL;DR: In this paper, 14C was determined in elemental carbon (EC) and different organic carbon (OC) fractions from ambient urban aerosols with aerodynamic diameter <10 μm collected in Zurich (Switzerland).

TL;DR: Evidence for oligomer formation for SOA from both precursors was given by an increasing abundance of compounds with a high molecular weight and by an increase thermal stability with increasing aging time.
