Variations in VOCs Emissions and Their O₃ and SOA Formation Potential among Different Ages of Plant Foliage.

ABSTRACT: Volatile organic compounds (VOCs) emitted by plant foliage play an important role in ozone (O₃) and secondary organic aerosol (SOA) formation. Their emissions can be influenced by the leaf age. We explored the VOCs emissions and their effects on the formation of O₃ and SOA from plant foliage in different ages. VOCs emissions from the young, mature, and senescent leaves of Ginkgo biloba, Ligustrum lucidum, and Forsythia suspensa were measured using the dynamic enclosure system and the TD-GC-MS technique. Based on the emission rates of quantified compounds, their potential to form O₃ and SOA was estimated. Results showed that there were significant differences in the VOCs emission rate and their composition among leaves in different ages.
