在人工空气系统中以环境浓度水平研究了Tenax采样期间萜烯和萜类化合物的臭氧分解，8-150 ppbv臭氧的有害影响取决于化合物的化学结构：饱和萜类化合物如1，8-桉叶素、樟脑和乙酸肉豆蔻酯不受臭氧影响，萜烯类和含一个C-C双键的萜类化合物的降解程度依次为：α-蒎烯<桃金娘烯醛附近的β-蒎烯<α-蒎烯<香茅醛附近的桧烯。含有两个或两个以上双键的化合物的降解顺序为d-柠檬烯>柠檬醛<芳樟醇<β-罗勒烯<萜品油烯
The ozonolytic decomposition of terpenes and terpenoids during sampling on Tenax is investigated in an artificial air system at ambient concentration levels, The detrimental effect of 8-150 ppbv ozone depends on the chemical structure of the compounds: saturated terpenoids such as 1,8-cineole, camphor, and bornyl acetate are unaffected by ozone, The terpenes and terpenoids which containing one C-C double bond are slightly decomposed in the order camphene < beta-pinene approximate to myrtenal < alpha-pinene < sabinene approximate to citronellal. The compounds containing two or more double bonds are significantly decomposed in the order d-limonene approximate to citral < linalool < beta-ocimene < terpinolene
