Analytical methods were developed for the screening of chemical substances in the oil spill accident.<BR>Headspace method was used for direct determination of volatile compounds in oil using gas chromatography/mass spectromety (GC/MS) method in scanning mode. Using this method, BTEX (benznene, toluene, etc.) and praffins were detected in Heavy oil.<BR>Solid-phase microextraction (SPME) was used for determination of volatile compounds in head space of water and air. SPME fiber with a 65μm Polydimethylsiloxane / Divinylbenzene coating was suitable for BTEX.<BR>5% hydrous silicagel column chromatography was used for analysis of chromatogram patterns of oils and separate paraffins and polycyclic aromatic hydrocarbons (PAHs) in heavy oil.<BR>PAHs were detected in spilled and drifted heavy oil of Nakhodka. The concentration of PAHs were similar to other heavy oil samples, but the concentrations of polar PAHs in drifted oil decreased compared with the original oil.
