The photoionization efficiency curves of phenanthrene, anthracene, fluoranthene, pyrene and triphenylene have been measured by VUV photoionization. All spectra show a similar resonance peak at around 17 eV. This phenomenon can be explained as being due to autoionization via a giant plasmon resonance. Autoionization has a negligible contribution to fragmentation processes which occur in the same energy range.

The fluorescence intensity of polycyclic aromatic hydrocarbons (PAHs) is higher in Brij-35 micellar solution than in methanol. Pyrene, benzc$ghilperylene and benzo[a]pyrene could be determined in the presence of up to a lOO-fold excess of other PAHs, the errors being lower than 5%. The relative stan
## Abstract Induction of putative preneoplastic hepatocytes which are resistant to cytotoxic effect of 2βacetylaminoβfluorene (2βAAF) by five carcinogenic polycyclic aromatic hydrocarbons (PAH) was tested using Ξ³βglutamyl transpeptidase (Ξ³βGT) as a histochemical marker enzyme.

Five polycyclic aromatic hydrocarbons (PAHs) were studied by means of chemical deoxygenation micelle-stabilized room temperature phosphorimetry (MS-RTP) with sodium sulfite as \(\mathrm{O}_{2}\) scavenger and with thallous nitrate as heavy atom perturbation in sodium dodeyl sulfate micellar media.

Six polycyclic aromatic hydrocarbons (PAHs) are studied by chemical deoxygenation microemulsion-stabilized room temperature phosphorimetry with sodium sulfite as an oxygen scavenger and thallous nitrate as a heavy atom perturber in sodium dodecyl sulfate medium. Several factors influencing room temp
