Determination of some heavy metals in seagrass "Poisdonia oceanica"(L.) Delile of Benghazi Coast in Libya "Mediterranean"

The heavy metals (Cr, Cd, Zn, Co, and Pb) concentrations were determined in Seagrass Poisdonia oceanica (L.) Del. Tissues. Samples that collected from five sites along 30Km north and south of Benghazi, the second largest city in Libya, [Northern sea of African coast (Mediterranean)]. The technique used for the analysis was Flame Atomic Absorption Spectrophotometer (model novAA300).The study shows that an elevated concentration of Zn, Cd, and Pb were found in most samples particularly those collected near the discharge point of city sewages effluent, and the north Benghazi power station site. The concentration of Cr and Co was very low in all samples except for those collected near the city. Statistical analysis (one-way ANOVA) indicated that the Seagrass Poisdonia oceanica (L.) Del. tissues had different levels of metal bioaccumulation and might be used as a biomoniotors for trace metals
