Zawartość terpenów w powietrzu młodszych i starszych lasów

Abstract

The database contains results regarding the chemical composition of air in younger and older Scots pine (*Pinus sylvestris* L.) and European beech (*Fagus sylvatica* L.) stands, specifically focusing on terpenes. Air samples were collected between July 18 and October 2 using portable air samplers and sorption tubes packed with Tenax TA. Compounds captured on the sorbent underwent thermal desorption followed by analysis using gas chromatography with flame ionization detection (GC-FID). Qualitative identification of terpenes was performed by comparing the retention times of compounds in the samples with those of certified standards and by using linear retention indices. Quantitative determination was based on five-point calibration curves prepared for the analyzed compounds. A standardized analytical procedure—encompassing sampling, thermal desorption, and GC-FID analysis—was applied to all samples, enabling a comparison of terpene concentrations across the studied forest stands.
