Characterization of organic species and functional groups in pollen, fungi, algae, and bacteria bioaerosols

Little is known about the chemical composition of bioaerosols (pollen, fungi, algae, bacteria). In this study, several bioaerosols were characterized for their functional groups with 1H-NMR and were quantitatively analyzed for individual organics.

Interference of sea salt in capture vaporizer-ToF-ACSM measurements of biomass burning organic aerosols in coastal locations

Measurements of biomass burning organic aerosols using the capture vaporizer-ACSM are interfered with by sea salt aerosols, as both have m/z 60 as a marker ion and the capture vaporizer is able to detect refractory particles like sea salt.

Analysis of the effect of abiotic stressors on BVOC emissions from urban green infrastructure in northern Germany

Drought stress was identified as the most important abiotic stressor that modulates emissions of biogenic volatile compounds in a Northern European city. Isoprene concentrations were reduced by 65% under drought stress during the growing period compared to non-stress conditions.
