Compositional characteristics and origin of polycyclic aromatic hydrocarbons(PAHs), which should be strongly regulated for environmental protection in the crude oils and petroleum products, have been investigated by gas chromatography-mass spectrometry(GC/MS). In the crude oils analyzed, two-rings compound(naphthalene) of PAHs was detected around $72.3\sim93.5%$, but five- or six-rings compound of PAHs was not detected. In the crude oils analyzed, the molecular ratio indices of Phe/Ant(phenanthrene/anthracene)>15, Fla/Pyr(fluoranthene/pyrene)<1, BaA/Chr(benzo (a)anthracene/chrysene)$\leq0.4$ could be effectively applied, and we found that the origin of PAHs was petrogenic sources. Total PAHs concentrations in the crude oils were increased with increasing API gravity and with decreasing sulfur contents of the analyzed crude oils. Five- or six-rings compound of PAHs were not included in ail petroleum products except bunker-C. Furthermore, the molecular ratio indices of Phe/Ant(phenanthrene/anthracene) vs. Fla/Pyr(fluoranthene/pyrene) could be effectively applied as the standard for the PAHs contamination criterion at the other Korean areas.
