ABSTRACT: Concentrations
of Fe, Cu, Pb, Zn, Cd and Ni were determined in the red alga Corallina officinalis (Linnaeus, 1758), the green alga Ulva lactuca (Linnaeus, 1753) and
sediment sampled in four stations of the coastline of Hona?ne (extreme Western
Algeria). The abundance of metal concentrations in algae and sediment samples,
is in the following order: Fe > Zn > Pb > Ni > Cu > Cd. The
schematic representation by PCA reflects a strong correlation of the corallina
with Cd and Pb, the ulva with Zn and Ni and sediment with Cu and Fe, in
addition, to homogeneity of rehearsals in each matrix. The results of this study validate
the use of these species as reliable tools for biomonitoring of metal pollution
of coastal ecosystems, even if the levels of heavy metals in sediment and algae
from the coastline of Hona?ne are in general, very low compared with those from
other geographic areas and by guidelines.
