The qualitative and quantitative composition of volatile compounds emitted and absorbed by undamaged boles of lodgepole pine trees ( Pinus contorta murrayana) was determined by trapping the compounds on activated charcoal in the field. Among eight samples, each from a different tree, total volatile flux ranged between 60.61 μg m −2 day −1 emitted and 0.61 μg m −2 day −1 absorbed to give a mean of 11.89 μg m −2 day −1 emitted. The main compounds emitted were β-phellandrene, p-cymene, β-pinene, an oxygenated monoterpene, and α-pinene. Absorption of β-pinene from that present in ambient forest air was observed in two samples.
