RESULTS 



The six metals studied are considered from the 

 viewpoint of differences in concentrations be- 

 tween the two species, variable concentrations 

 in different tissues, and seasonal variations. 

 Results are expressed in Atg g"^ wet weight for 

 all elements except mercury, which is expressed 



in ng g 1 wet weight. These can be converted to 

 dry weight using the factors presented in Table 3. 



Mercury 



The seasonal distribution of mercury in various 

 tissues in both the sardine and anchovy ranged 

 from 5 to 610 ng g^ wet weight (Table 4). During

 tissues analyzed for metal concentrations.

 sardine Sardina pilchardus and anchovy Engraulis encrasicholus from the 

 Adriatic Sea.
