Abstract

Investigations on the Temporal Behaviour of ^C Incorporation into Biogenic VOCs Guest contribution Christoph Holzke, Johannes Kahl and Thorsten Hoffmann InstitutfUr Spektrochemie und Angewandte Spektroskopie (ISAS), Bunsen-Kirchhoff-Str. 11, 44139 Dortmund, Germany Introduction and experimental Volatile organic compounds (VOCs), like mono- and sesquiterpenes, are released by vegetation and play an important role in the composition of the troposphere (Fehsenfeld et ai, 1992). They react very rapidly with other atmospheric constituents, such as OH radicals and ozone. Otherwise they can also contribute to the generation of ozone, radicals and peroxides. Until now, large uncertainties exist about the relationship between terpenoid biosynthesis and emission behaviour of plants. Detailed information about the metabolite turnover will provide insight into the sites and pathways of terpenoid biosynthesis. Therefo
