A comparative Study of Heavy Metals Bioaccumulation in Different Types of Marine Algae from the Sudanese Red Sea Coast
الملخص
This study aimed to determine the concentrations of heavy metals, Cr, Mn, Ni, Cu, Zn, Cd, and Pb in three main groups of marine algae; green, brown and red from the Sudanese coastal water of the Red Sea at seven main locations. The results of the study showed an affinity towards essential elements (Manganese, Copper and Zinc).Among the essential elements, highest concentration was exhibited by Mn in all the species, irrespective of their classification,(average range from16.60to 172.53mg/g), where brown algae Cystoseirasp. contains the highest uptake of Mn (257.32 mg/g). However, green algae Enteromorphasp. contains the highest uptake of Cd and Pb (0.25 and 2.40 mg/g) respectively, these species suggesting its suitability for utilization as biomonitor in the Red Sea coastal environment.
