Figure l.-Station locations' collections oi Arctic a islandica. Stations 367, 335 and 349 are on the Scotian Shelf at the following coor- 

 dinates: Station 367 (lat. 43°44'N, long. 61°08'W), Station 335 (43°25'N, 61°42'W) and Station 349 (43°21'N, 61°23'W). 



tional AA techniques. Reagent blanks were carried 

 through the same procedure All reagents used were 

 of trace metal analytical grade Deionized water was 

 of 18 megohm purity. The National Bureau of Stan- 

 dards (NBS) SRM 1566, freeze-dried oyster homog- 

 enate, was used as the tissue standard. Recoveries 

 were at least 80% of this standard in all cases. 



RESULTS 



The analytical results for organic contaminants are 

 presented in Tables 1 (PHC and PCB) and 2 (PAH). 

 PHC values are given as total saturated and aromatic 

 hydrocarbons as determined by GC 2 . PCB values 

 are given as total tri-, tetra-, penta-. hexa-, and hepta-
