title: Capillary GC/MS determination of organic sulfur compounds detected in oyster and mussel caught in the sea as an oil pollution index.
abstract: The organic sulfur compounds usually contained in crude oil were used as a marker of oil pollution in shellfish. The oyster (Crassostrea gigas) and mussel (Mytilus edulis) were caught in the Seto Inland Sea of Japan. Capillary-column gas chromatography/mass spectrometry (GC/MS) of extracts showed the presence of organic sulfur compounds of dibenzothiophene and alkyl dibenzothiophenes (C1-C3). The concentration factor of organic sulfur compounds in the oyster and mussel was determined by gas chromatography using a flame photometric detector.
