Cd, Cr, Cu, Pb, and Zn concentrations in Ulva lactuca, Codium fragile, Jania rubens, and Dictyota dichotoma from Rabta Bay, Jijel (Algeria)

Abstract

Concentrations of Cd, Cr, Cu, Pb, and Zn were determined in algae samples collected from the Rabta Bay in the Mediterranean Sea, Algeria. The levels of heavy metals in the macroalgae, Ulva lactuca, Codium fragile (green algae), Jania rubens (red algae), and Dictyota dichotoma (brown algae) recorded high concentrations except for Cd. Moreover, Zn was the most predominant metal in the seaweeds. The obtained HM contents indicate that different species demonstrate various degree of metal accumulation and the obtained higher values in site 1 of the studied zone can be attributed to the discharge influence of two rivers (Mouttas and Larayeche Rivers), entering the Mediterranean Sea and local pollutant emissions. The abundance of heavy metal concentrations in the macroalgae samples was found in the order below: Zn > Cu > Pb > Cr > Cd from the studied zone. The highest amounts of heavy metals in algae samples were Cd, Cu, and Pb in brown algae, and Cr and Zn in green and brown algae from the studied zone (Rabta Bay).

Use of Sediment and Algae for Biomonitoring the Coast of Honaïne (Far West Algerian)

“…In this study, it is noted to the contrary, where a preferential accumulation of Zn Corallina officinalis relative to Ulva lactuca, which is in agreement with the results reported by [6] [27].…”

“…This agrees with the results of [25] from Alexandria (Egypt); [26] from Ghazaouet for Corallina officinalis and [27] from Jijel on other calcified red algae: Corallina mediterranea and Jania rubens from Algeria. This is may be due to the affinity of Pb to the calcified structures [28].…”

Ecological Quality Status of the Algiers coastal waters by using macroalgae assemblages as bioindicators (Algeria, Mediterranean Sea)

“…Unfortunately, there are no studies on the application of the EEI-c index to macroalgae inhabiting waters off African coastal countries and Algerian coasts. Most related studies have focused on macrofauna to assess the water quality (Bakalem et al, 2009;Grimes et al, 2010) or measuring the concentration of heavy metals in an accumulator species and seawater (Soualili et al, 2008;Laib & Leghouchi, 2012;Belkacem et al, 2016).…”

A new biosorbent for the removal of Cu(II) from aqueous solution; red marine alga,Ceramium rubrum

“…Various species of marine alga were used as biosorbent for removal of heavy metals from environmental samples (Yu, 1999;El-Sikaily, 2007;Fagundes-Klen, 2010;Laib, 2011;Esmaeili, 2011;Nessim, 2011). But to the best of our knowledge, there is no significant study on the use of red marine alga, Ceramium rubrum for this purpose although there are a lot of studies on evaluation of its structure (Miller, 2002), determination of its metal content (Jordonava, 1999) and its pharmaceutical effect such as antiviral (Zagal, 2004) and antibacterial activity (Kesternich, 1997).…”
