“…Tada and Suzuki, 15 found that the main factor controlling the adsorption of metal was organic matter from the fine bottom mud. A remarkable adsorption decrease was found due to the destruction of the organic matter content.…”

The vertical distribution of Al, Cu, Fe and Zn in the soil salt marsh of the river Sado estuary was studied. The results obtained by an acid digestion procedure, indicate that the mean values at the first sampling point (near the Atlantic Ocean and very close to a populous city) are lower when compared with those found at the other Stations (approximately 8.0 and 20.0 km upstream), where they are very similar. These findings are related to the different nature of the soil matrix (essentially sand at Station 1 and silt-clay at Station 2 and 3), and the reduced availability of the sandy fraction to bind trace metals. A correlation analysis for all the metals in different soil cores indicate that the correlation values at Station 1 are, generally, not significant at a 0.05 significance level.

“…L'effet du pH sur l'adsorptiorï des métaux a été particulièrement étudié (BALISTRIERI et MURRAY, 1984 ;TESSIER et ai, 1989 ;TADA et SUZUKI, 1982 ;DHILLON et ai, 1985 ;BASTA et TABATABAI, 1992a, b ;ZHU et ALVA, 1993) ; ainsi une augmentation du pH favorise l'adsorption métallique sur la fraction réductible des sédiments (oxydes de fer et de manganèse), après échange des cations métalliques avec les ions H + sur certains sites de surface. La formation de sulfures, la biodégradation de la matière organique, toutes deux fonctions de l'acidité du milieu permettent d'interpréter la spéciation des métaux dans les sédiments et leur biodisponibilité.…”
