Key Points

This research aims to understand how β-caryophyllene contributes to secondary organic aerosol formation through the role of extremely low-volatility organic compounds.
Utilized experimental modeling to assess β-caryophyllene and ELVOC interactions.
Analyzed the composition of secondary organic aerosols generated from β-caryophyllene autoxidation.
Evaluated the impact of ELVOCs on new particle formation in atmospheric conditions.
Identified a substantial increase in secondary organic aerosol levels with the presence of ELVOCs.
Demonstrated that β-caryophyllene is a significant precursor in new particle formation processes.
Revealed complex interactions between β-caryophyllene and other organic compounds contributing to aerosol composition.

Abstract

β-caryophyllene (BCARY), a prevalent biogenic sesquiterpene, is an important precursor of secondary organic aerosol (SOA). While extremely low-volatility organic compounds (ELVOCs) formation by autoxidation may be critical to accurately represent...
