Özet

The concentrations of four metals (copper, cadmium, zinc and lead) were quantified in blue crabs (Callinectes sapidus) tissues collected in January, April, June and September at two stations in Mersin Bay, northeastern Mediterranean Sea, using ICP-MS. The metal concentrations in crabs from the two stations differed significantly. The hepatopancreas was the major organ accumulating metals, followed by gill and muscle tissues. Except for lead, the highest concentrations of metals were measured in the hepatopancreas. The hepatopancreas had higher concentrations of all heavy metals (Cu 321.1 +/- 4.30; Zn 182.2 +/- 3.40; Cd 48.2 +/- 2.00) compared to gill (Cu 90.2 +/- 1.35; Zn 104.3 +/- 2.30; Cd 22.3 +/- 3.40) and muscle (Cu 19.1 +/- 1.10; Zn 55.1 +/- 3.25; Cd 2.5 +/- 0.20). Among the metals analyzed, Cu, Zn and Pb were the most abundant in the different tissues while Cd was the least abundant in C. sapidus. Seasonality in the levels of the four metals was determined.The highest concentrations of all metals were observed in the June (Zn 55.1 +/- 3.25; Cu 19.1 +/- 1.10; Cd 2.5 +/- 0.20; Pb 5.1 +/- 0.18) compared to all other months (Zn 34.1 +/- 3.23; Cu 11.1 +/- 1.15; Cd 0.9 +/- 0.20; Pb 3.1 +/- 0.21).
