Gas Phase Terpene Oxidation Products. A Review.

Terpenes are emitted in large quantities from vegetation into the troposphere, where they react readily with ozone, OH and NO radicals leading to a number of oxidation products. The current knowledge about gas - phase terpene oxidation products is reviewed. Their formation and decomposition pathways, their products and their relevance for the troposphere, and their chemical analysis are discussed. Data on oxidation kinetics, and products yields is presented for 23 terpenes and 65 oxidation products. A total of 84 references are quoted.JRC.(EI)-Environment Institut
