The location of estuaries downstream of rivers favors their contamination by many polluting products, especially heavy metals. In the present work, we evaluated Fe, Zn, Cu and Pb concentrations in the sediment and in the flesh of two mollusc species living in the Sebou estuary (Morocco), i.e. Solen marginatus
and Scrobularia plana
The results have shown that the concentrations of the four metal elements were lower in the sediment than in the flesh of both species suggesting a bioaccumulation of some metal elements by these organisms. However, the concentrations of these elements varied between the two species and depended on the season for both materials (sediment and mollusc flesh). For S. plana, flesh Zn concentrations were relatively high and contrasted to those of Cu. As for lead, flesh concentrations were higher than those noted in the sediment.
On the other hand, an important bioaccumulation of Fe was observed in S. marginatus. This species behaved contrastively to S. plana with regards to Zn concentrations and showed a good ability to avoid lead excess in the medium. Pages: 223-227 | 850 Views 39 DownloadsDownload Full Article:
