Kouassi, A. Hachem, A. Morsad, Y. Bokra] This study is devoted to the determination of percentages of fluoride and chloride in Ebrié located in Abidjan and wells located in the central and southern areas of Ivory Coast. Nondispersive X-Ray Fluorescence method and potentometric method with ion sensitive electrodes have been used. For underground water, the concentrations obtained are, with the exception of some isolated cases, lower than the upper limits tolerated for drinking water. These waters are drinkable. In a lagunal environment, the results show that the elements drawn from the bottom of the sea, through the Vridi Canal, spread in the lagoon. The ratio of the concentration of elements and the corresponding salinity confirm the fact that chloride undergoes an essential dilution in the lagoon due to contact with continental waters. A semi-diurnal periodicity of the concentration of elements has been firmly established. This period is the same as the tidal one. Akadémiai Kiadó, 1992 Kouassi E.
