Abstract

Organic Aerosol Formation from the Oxidation of Bornyl Acetate with Hydroxyl Radicals Guest contribution C Coeur, V. Jacob, P. Foster and P Baussand Laboratoire GRECA (Groupe de Recherche sur I 'Environnement et la Chimie Appliquee), 39-41 Bvd. Gambetta, 38000 Grenoble, France The gas phase reaction of bornyl acetate (l,7,7-trimethyl-bicyclo[2,2,l]-heptan- 2-ol-acetate), VOC emitted by Mediterranean trees (orange and mandarin trees), with hydroxyl radicals has been studied in a smog chamber. It was found that the reaction of bornyl acetate with OH radicals leads to organic aerosols. The chemical composition of the aerosol was studied. On the basis of mass spectral data, l,7,7-trimethyl-6-acetyloxy-bicyclo[2.2. l]-heptan-2,3-dione has been identified in irradiated CHgONO-NO-air-bomyl acetate mixtures. The aerosol carbon yield, the fraction of the carbon initially present that is converted to aerosol, has been esti
