Aquatic ecosystems are highly polluted with heavy metals arising from anthropogenic and terrigeous sources. The object of this study was to investigate the current status of metal pollution of water and sediment from Wadi Bouhamra which is a major antropic source of Annaba Gulf pollution. Samples were collected during the various seasons and 13 metallic trace elements (MTE) were analyzed by inductive coupled plasma optical emission spectrometer (ICP-OES) and atomic fluorescence. The obtained results showed high metal contamination of water and sediment. According to French standards, water is altered respectively by Pb, Zn, Cu, Cd and Cr giving it a poor quality, whereas, sediment is mainly contaminated by Cd, As, Cr, Zn and Pb that assign it a passable ability to biology. Finally, the statistical principal component analysis (PCA) was used to identify the industrial, agricultural and domestic sources of this pollution.
