抄録

Thirty-one n-alkanes (C₁₀-C₄₀), two branched alkanes (pristane and phytane), eight alkyl dibenzothiophenes and 22 polycyclic aromatic hydrocarbons (PAHs) were identified from nine oil samples collected from the coasts of the Niigata Prefecture during May to August 1997. Compositions and relative ratios of these compounds to C₃₀ in the oil samples were compared with those in the heavy oil (N-1) from a Russian-registered tanker, Nakhodka which has broken and sunk on January 2, 1997, in the Sea of Japan.<BR>Low molecular weight compounds, such as n-alkanes with C₁₀-C₂₂, alkyl dibenzothiophenes and PAHs decreased by weathering in the environment. Volatilization rather than elution and/or bio-degradation seems to be a major factor for the disappearance of the compounds. Six among nine oil samples from the coasts did not seem to be originated from Nakhodka based on the comparison of the compositions and the relative ratios of the target compounds in the oil samples with those of the oil from the tanker.
