摘要

PROBLEM TO BE SOLVED: To develop a means for effectively utilizing terpene compounds contained in tree leaves so that branches and leaves stemming from tree thinning and pruning can be utilized as a resource.

SOLUTION: With the goal of developing a means for effectively utilizing terpene compounds contained in tree leaves and utilizing branches and leaves stemming from tree thinning and pruning as the resource, there are provided a monoterpene component-rich essential oil containing 90% or more of monoterpene components; a method for producing the monoterpene component-rich essential oil which includes subjecting coniferous leaves to microwave steam distillation and collecting a distillate thus obtained; and a method for removing environmental pollutants which includes bringing the monoterpene component-rich essential oil into contact with atmosphere containing the environmental pollutants.
