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 (chemical- 

 ly) 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.
