9) Oysters were initially heavily impacted by oil (several
thousand ppm) and after two years (June 1980) traceable
AMOCO CADIZ residues are still evidenced by homologous series
of isoprenoid alkanes, phenanthrenes and dibenzothiophenes.
Petroleum residues persist approximately at the 100 ppm
level .
10) Fish do not appear to have been directly impacted (chemically)
by the spillage to any significant extent.
11) Compositional profiles traceable to AMOCO CADIZ oil are likely
to "disappear" from all sediments within another year (i.e.
1982; four years after the spill) although this should be
confirmed by direct measurements and attention to molecular
marker compound distributions.
