THE EFFECT OF WEIGHT COMPOSITION OF SARDINA PILCHARDUS FISHED FROM BENGHAZI COAST ON ITS CONTENT OF MERCURY AND LEAD
This study was conducted in order to evaluate the contents of mercury, and cadmium common fish in Benghazi coast nominated Sardina Pilchardus. The effects of the fishing area and weight composition on the accumulation of these minerals were also studied.
Data showed the concentration of mercury and lead in the tissues (muscles, gills, gut, and spinal column) of Sardina Pilchardus from Benghazi coast was 0.2331 ppm and 8.403 ppm, respectively. The weight composition of Sardina Pilchardus no significant differences were found for concentration of lead; the less concentration was observed in mussels and less concentration of mercury was found in the gut.
There was a fishing area effect on the content of these minerals; whereas the effect was clear for the concentration of lead in muscles, gills and spinal columns. The same effect was found for cadmium in the gill, gut and spinal column, while was an effect on mercury concentration was only in the spinal column.
