Short summary
Targeted derivatization and non-targeted analysis with Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) were used to reveal the molecular composition of carbonyl molecules in PM2.5, and the important role of carbonyls in increasing the oxidative potential of organic aerosol was found in real samples.
