Total monoterpene levels of the order of 100 μg/m3 were assessed in the summer night air of a typical young planted forest of Scots pine (Pinus silvestris) in Sweden. These concentrations are much higher than those reported in previous studies of ambient monoterpenes. Predominant species were α-pinene and 3-carene. Camphene, β-pinene, myrcene, β-phellandrene and limonene were other prominent components determined. The monoterpenes were shown to originate almost exclusively from Scots pine and the proportions between them to be characteristic of this conifer species.

Forest decline due to photooxidants formed from emitted hydrocarbons was a major environmental issue in Sweden when this study was performed. The assessment of high levels of reactive biogenic terpenes under certain conditions emphasized the complexity of the problem.
