Intérêt de la FRX-RT (Fluorescence des Rayons X à Réflexion Totale) pour le suivi de la pollution des eaux des rivières par les métaux : Cas de oued Bouregreg (Maroc)

Autor: M. Ibn Majah, M. Bounakhla, Pierre Dubois, A. El Hamdaoui, Simone Cohen-Jonathan

Publikováno v: Cahiers de l'Association Scientifique Européenne pour l'Eau et la Santé. 7:15-22

Les analyses des metaux dans les eaux de l'estuaire de Bouregreg, ont ete effectuees par fluorescence des rayons X a reflexion totale (FRX-RT). L'objectif etant d'une part d'evaluer le taux en elements majeurs et traces dans l'estuaire de Bouregreg,

Anthropogenic radionuclides in the water column and a sediment core from the Alboran Sea: application to radiometric dating and reconstruction of historical water column radionuclide concentrations

Autor: M. Ibn Majah, M. Benmansour, José-María Abril, S. Mulsow, A. Laissaoui, N. Ziad

Global fallout is the main source of anthropogenic radionuclides in the Mediterranean Sea. This work presents 137Cs, 239+240Pu and 241Am concentrations in the water column in the southwest Alboran Sea, which was sampled in December 1999. A sediment c

Distribution of anthropogenic radionuclides in Moroccan coastal waters and sediments

Autor: M. Ibn Majah, M. Benmansour, Pavel P. Povinec, A. Chafik, S. Benbrahim, A. Laissaoui

Concentrations of anthropogenic radionuclides ( 137 Cs, 239, 240 Pu and 241 Am) were measured in surface seawater, water column and sediment samples collected in Moroccan coastal waters. The average activity concentrations in surface water were 2.7 m
