ResumoThe spatial and temporal retention of metals has been studied in water and sediments of the Gavião River, Anagé and Tremedal Reservoirs, located in the semi-arid region, Bahia -Brazil, in order to identify trends in the fluxes of metals from the sediments to the water column.The determination of metals was made by ICP OES and ET AAS.The application of statistical methods showed that this aquatic system presents suitable conditions to move Cd 2+ and Pb 2+ from the water column to the sediment.
