Waters Metallic Typology of Oued Tisslit-Talssint (Morocco Oriental)

In The purpose of the management and conservation of the aquatic environment of WadiTislit-Talssint, a principal components analysis of eight heavy metals, has been conduct during the period of low water (May 2011). The visualization of results has allowed us to show that, Mn, Fe and Ni are positively correlated to the axis F1, unlike the heavy metals: Co, Cu, Cd and Zn which is associated with this axis negatively. On the main axis F2, only the problem that a positive correlation, as well the application of the principal component analysis on these results, shows that we have two groups of stations: a first group of stations in the positive part of the F axis1, characterized by waters with high concentrations (Mn, Fe and Ni), in the stations S0 and sc1.A second group of stations in the negative part of the F axis1, characterized by waters with high concentrations (Cu, Cd, Zn, and CO in the stations (SR1 and SR2). This enrichment in metallic elements is to put in relationship with the inputs of wastewater and solid waste of the commune of Talssint, flowing upstream of the stations SR1 and directly at the level of the station SR2.
