A universal method for the efficient separation and detection of partially oxidized polycyclic aromatic hydrocarbons has been developed and was applied to real samples. These method bases on a liquid chromatographic separation with a phenyl-modified silica reversed stationary phase and mass spectrometric detection with APCI-single-quadrupole-MS. The applicability was demonstrated with 73 reference substances and with real samples of environmental, medical, and technical relevance. Another topic in this work was the characterization of products and the kinetic from the reaction of ozone with polycyclic aromatic hydrocarbons, especially with benzo[a]pyrene. Several up to now unknown degradation products and physico-chemical parameters could be determined (rate coefficients, adsorption equilibrium constants, etc).
