ABSTRACT Samples of sediment were taken at intervals between 1979 and 1986 from soft sediment locations in the Aber Benoit, an estuary heavily impacted by the Amoco Cadiz oil spill of 1978, and from a comparable reference site outside the spill zone. Each sample was analyzed for aliphatic hydrocarbons by capillary gas chromatography. The data demonstrate the progressive weathering of the Amoco Cadiz oil resulting in an assemblage of biogenic hydrocarbons similar to the reference site by 1986 at all but the most heavily impacted locations. The data indicate that any residues of weathered Amoco Cadiz oil present in 1985-86 were in the final stages of degradation.

Some of the volatile metabolites of eight species of blue-green algae of the genera Oscillatoria, Phormidium, Aphanizomenon, and Anabaena were identified by gas chromatography mass spectrometry (GC-MS). As a result, five sesquiterpene alcohols (C15H26O) and two sesquiterpene hydrocarbons (germacrene-D and γ-cadi-nene) were detected in the cultures of Oscillatoriasplendida. O. amoena, and Anabaenamacrospora. Three aliphatic hydrocarbons (n-heptadecane,1-heptadecene and 7-methylheptadecane) were also identified in the cultures of most of these algae. None of these compounds appeared to impart an unpleasant taste or odor to water supplies.
