“…These may be due to the fact that different plants had different tolerant mechanisms and uptake models to metals [39]. Other researchers also indicated that the accumulation of metals (e.g., Sr) in plants was affected by site-specifi c and plant-specifi c parameters such as the capacity of plant species, the availability of metals, and other competing elements [27,40,41]. For reeds, root was the main pathway for trace metals to enter tissues [42].…”

“…Each data point is the mean of four observations (df= 53). The trendline shown is representative of the more rapid decrease in CR from 0 to approximately 0.5% illite, followed by a more gradual reduction from 0.5 to 5.0% illite time between 137 Cs and the sediments, the less mobile it becomes (Evans et al 1983;Crusius and Anderson 1995;Sanchez et al 2002). In addition to fixation by increasing contact time, 137 Cs can be experimentally aged in sediments by exposure of the sediments to wet dry cycles (Madruga and Cremers 1997;Sanchez et al 2002).…”

“…Comparison of other US sites with 137 Cs contamination, such as Oak Ridge, TN and Hanford, WA, provides evidence that sediment composition influences the mobility of 137 Cs within the system, and clay soils more effectively sequester 137 Cs than other types of soils (Sharitz et al 1975;Evans et al 1983;Carlton et al 1992;Guivarch et al 1999;McKinley et al 2001). Since 137 Cs is most strongly sorbed to the clay fraction of soils or sediments, the amount of clay and the type of clay present affects its mobility (Sawhney 1972;Comans and Hockley 1992;Hinton et al 2001;Sanchez et al 2002;Hinton et al 2006).…”

“…Les expérimentateurs se sont attachés à définir une relation entre le Kd du césium et les paramètres du sol qui influent sur les sites de sorption, en particulier : argiles, potassium et ammonium échangeables et CEC (Yasuda et al, 1995 ;Elejalde et al, 2000 ;Rigol et al, 2002 ;Sanchez et al, 2002 ;Camps et al, 2003Camps et al, , 2004. Différents modèles ont été décrits, basés sur le paramètre RIP (Radiocesium Interception Potential) qui prend en compte les sites spécifiques et non spécifiques du césium.…”

“…Sous sa forme la plus simple, il permet une évaluation de Kd L en connaissant les teneurs en potassium et en argiles et la capacité d'échange cationique du sol. En outre l'étude de Sanchez et al (2002) effectuée sur une trentaine de sols différents dont une vingtaine de sols organiques modélise l'influence de l'état de végétalisation du sol sur le Kd. Ces modèles semiempiriques permettent une évaluation du Kd du césium « labile » à partir de paramètres ordinairement mesurés dans les sols agricoles.…”
