gonad. In spring, high Ni content was recorded in digestive
gland than in gill, RST, and gonad.
For Sercouf mussel, far high Ni levels were found in the gill
(winter) and the digestive gland (spring) compared with the
remainder organs; similar Ni contents (not far) were found in
gills, digestive glands, and gonads throughout summer and
autumn seasons with highest levels found in the digestive
glands.
All organs of Algiers port mussels were more Ni loaded over
summer and autumn than in winter and spring seasons. On the
other hand, significant Ni contents were found in all digestive
gland samples compared with the other organs with the
