concentrations of Pb were found in the digestive gland
(spring) and the gill (autumn and winter) compared with
those in other organs. During summer, the distribution
of Pb in different organs was found as follows: digestive gland ˃ gill ˃ gonad ˃ RST.
For Sercouf mussels, significantly high Pb concentrations
were found in the RST (summer), gill (autumn), and the
