gland in winter) at Algiers port.
Much far higher Mn concentrations were found in the digestive gland of mussels collected at Figuier, during all sampling
seasons (from 3 to 5 times larger than other organs); not far
Mn concentrations were found for the three organs gill, RST,
and gonad throughout the four sampling seasons.
At Sercouf site, high Mn contents were found in the gill
followed by the digestive gland during both summer and autumn seasons. However, moderate Mn contents were found in
RST and gonad. Mn content over winter was significantly
