The basin of the Annaba Gulf constitutes the ultimate receiver of innumerable chemical substances resulting from various anthropic activities. These telluric discharges are potentially accompanied by biocidal chemical compounds. In order to preserve the quality of coastal waters and limit these flows that are dangerous for the marine environment and human health, seasonal monitoring (year 2009-2010) of the physico-chemical quality of liquid effluents from Fertial (complex for the manufacture of phosphate fertilizers and phytosanitary products), as well as the waters of two wadis (Boujemaâ and Seybouse), which are the main sources of water pollution in the bay, was carried out. The determination of the multi pesticide residues was carried out by GC/MS. The results show that the Boujemaâ wadi is mainly polluted by organochlorine and organophosphate insecticides, herbicides and fungicides. The Seybouse wadi is mostly altered by organophosphorus insecticides, herbicides and fungicides.
