4.2 Results Based on analyses of petroleum hydrocarbons in tissues of five species of molluscs, performed as part of this program (see Section 2), all four bays received some oil during or after the simulated oil spill. Mya truncata from Bay 10 became the most heavily contaminated with petroleum hydrocarbons, followed in order by clams from Bays 9, 7, and 11 (Table 4.1). Mya from the two dispersed oil bays (Nos. 9 and 10) accumulated the most oil immediately after the spill. The mean concentration of petroleum hydrocarbons in clams from Bay 11 (oil alone) increased between one-day and 2 weeks post-spill. Clams from the reference bay (Bay 7) were contaminated with a mean of 114 ppm (range 60-194 ppm in clams from the 5 stations on the 7-meter transect) one day after the spill, indicating that some oil reached this bay. Before the spill, clams from all four bays contained similar low levels of petroleum hydrocarbons. There was a great deal of variation among replicates, experimental bays, and sampling times in the concentration of carbohydrates and lipids in the tissues of Mya truncata (Table 4.1). Mean concentrations of free glucose were higher in clams from all four bays two weeks after the simulated oil spills (second post-spill sample) than in samples collected at the two earlier sampling times. There was a drop in the concentration of free glucose in clam tissues between the pre-spill and first post-spill samples in Bay 10 (dispersed oil) and 11 (oil alone). Glucose concentrations in tissues of clams from the four bays were nearly the same at the time of the second post-spill sampling. In clams collected before the spills, clams from Bays 9 and 10 had significantly lower tissue glucose concentrations than clams from Bay 11. Immediately after the spill, clams from the three experimental bays (9, 10, and 11) had significantly lower tissue mean glucose concentrations than clams from the reference bay (7). Clams from the more heavily oiled of the two bays receiving dispersed oil (Bay 10) had a significantly lower tissue glucose concentration than clams from the less heavily oiled, dispersed oil bay (Bay 9). There was a tendency for tissue glycogen concentration in clams to increase between the first, second, and third collections, particularly in clams from the reference bay. In clams from Bays 10 and 11, mean tissue glycogen concentrations dropped between the first and second post-spill samples. The mean concentration of tissue glycogen in 81
