In this study, an analytical procedure was evaluated for the determination of atmospheric PAH, both in gaseous and particulate phases. The method involves Soxhlet extraction of the filters and Tenax adsorbent, followed by a clean-up stage using a silica mini column prior to analysis by reversephase HPLC with wavelength programmable fluorescence and UV detection. A total of 18 PAH were identified and quantified, all of which have been of environmental concern. In order to validate the methodology and to ensure compatibility of the results, the analytical method used for the determination of PAH was evaluatd with respect to the efficiencies of extraction and clean-up procedure, HPLC separation, and lower limits of detection. In addition, substrate dependency of PAH recovery was also investigated for the two type of filter(glass fiber and PTEF filters) and Tenax adsorbent.
