Abstract: | The aim of this paper is to study the reaction products of alpha-pinene, beta-pinene, limonene, 3-carene and sabinene with OH radicals by FT-IR spectroscopy and by HPLC-MS-MS, to evaluate the secondary aerosol formation. All gas phase reaction products were quantified using reference compounds. As source of OH radicals were used H2O2 and CH3ONO. The experiments were performed at low terpene concentration (0.9-2.1 ppm) and at high terpene concentration (4.1-13.2 ppm), using H2O2 and CH3ONO as sources of OH radicals. |
