TEs Contents,Distribution,Origin and Geochemical interactions in soils. Case study of two cultivated soils irrigated by raw wastewater (Mekn?s-Morocco)

      Аннотация: This book present a now and power methods in the environmental geochemistry with a studied cases. The cases study of the TEs behaviours in cultivated soils irrigated by a raw wastewater in Ourzirha area (North-Western of the Meknes City). Different physicochemical data of studied profiles were put at various analyses to evaluate and discuss the principal phenomena controlling the contents of these micropollutants on the studied profiles. Indeed, the chemical assessments calculation us allowed to determine the vertical dynamics of the considered TEs. An approach of multivariate statistical analysis was carried out on the various physicochemical data of the samples taken on the studied soils for predict the sources of TEs on the profiles and to see their various associations. The results of this study, shows the presence of a significant concentrations of TEs on the levels of the surface horizons of the studied soils.
