| Résumé: | The level concentrations of heavy metals (essential and nonessential) were measured in different marine biota including cephalopoda, bivalve, crustacean and fish. The results reveal that these organisms show more or less the same order of distribution for each of the metals studied. The average concentrations of heavy metals exhibited the following decreasing order: cephalopoda > bivalve > crustacean > fish. The levels of metals in all studied samples are still comparable to those in their corresponding in the Mediterranean Sea. K (98-181μg/g) and Ca (547-1472 μg/g) were present at the highest concentrations in all investigated samples. Octopus and Sepia do not follow the general pattern. The highest value of Metal Pollution Index (MPI) in cephalopod was recorded in octopus (9.55) followed by sepia (7.62). Among investigated bivalve, the highest values of MPI were recorded in Mactra coralline (2.87). |
