3.5 Oysters and Plaice (Neff, Battelle) Samples of oysters and plaice from several impacted regions (L'Aber Wrac'h, L'Aber Benoit and Baie de Morlaix) and two supposedly unimpacted locations (Brest and Loctudy) were analyzed (Table 17, Figure 3.65) . The results of the oyster time series analyses are summarized in Table 18. Both the "gross" hydrocarbon parameters as well as the petroleum-associated aromatic hydrocarbons are presented. Though not "clean", the control (Brest) oysters are several times lower in gross concentration throughout the time period and an order of magnitude lower in aromatic hydrocarbon content than either of the impacted sites. It is not apparent if the levels have decreased substantially in either of the Abers, though aromatic levels are 3 to 4 times lower a year and a half after the spill. For <strong>com</strong>parison, levels of several of the non-petrogenic PAH <strong>com</strong>ponents (i.e. m/e 252) are presented. TABLE 17.
