Abstract

ABSTRACT: The paper reports the biomonitoring of metallic pollution generated by Jijel city and the port of Bouddis on the coast of Jijel (Algeria) using algological species algae [C. officinalis (Linnaeus, 1758) and Ulva lactuca (Linnaeus, 1753)] as bioindicators and biomarkers, which indicated heavy metal concentrations well above international standards (USEPA) and (IAEA-392), indicating unexpected levels of metals in seawater. The bioconcentration factor calculation has shown that these algae are excluders of Cr, accumulators of (Cu, Cd and Pb) and hyperaccumulators of Zn. These algae show different responses to toxic metals, depending on station, sampling period, age and phenological stage of specimens. These algae are suitable for use in biomonitoring for metallic pollution in coastal areas by expressing a specific range of biomarkers (MTs, GST, APX, CAT, carbonyls proteins and MDA).
