Accumulation of Some Trace Metals in Some Species of Sponges along the Syrian Coast

� ABSTRACT �

The aim of the present work is to test the value of some species of sponges living in Syrian coast as bio-indicators of trace metals contamination and compare results with concentration found in water. The concentrations of trace metals in sponges and water were determined in three sites distributed between Ras Al-bassit and Tartous coast. The

concentration of metals in sponges ranged between ( - ١٫٠ ) µg/g for Cd; Cu; Cr;Pb

while it was less than ١٫٠ µg/l in sea water. As for the mercury, the concentrations were

about ١٠ ng/g in sponges and in sea water they ranged between ( – ) ng/ l ; for zinc

the concentrations were too high: they ranged between ( – ) µg/g in sponges and

( ) µg/l in sea water. Most results indicate the high capacity of sponges to

accumulate trace elements form sea water; and the response of sponges to the changes of trace metals concentration was found to be significant between cleaner and clean area.

Keywords:

sponges , trace metals, bio-indicator, cadmium, chrome, mercury, lead, copper , zinc, Syrian coast.
