Third, although aerosol concentrations of any one aldehyde are unlikely to result in significant self-polymerization, cross-reactions between aldehydes and/or between aldehydes and alcohols may be significant and are specifically shown here to occur between propanal and two common aerosol organic species (glyoxal and methylglyoxal).
