Monoterpenes emitted to air from industrial barking of Scandinavian conifers.
Monoterpenes released to air were determined during single-log barking of timber at a saw-mill and during tumble drum barking of pulpwood at a TMP mill. Characteristic proportions of fourteen compounds were assessed by adsorbent sampling and gas chromatography. For Scots pine (Pinus sylvestris), the bicylic monoterpenes alpha-pinene and 3-carene predominated. For Norway spruce (Picea abies), alpha-pinene followed by beta-pinene were the major components. The proportions of beta-phellandrene and myrcene from spruce were remarkably high from barking compared to wood processing. Environmental aspects on the emissions are discussed.
