“…1-a showed that Mata 1 presented a 137 Cs deficiency in the 0-2 cm profile, which was concordant with the value of soil loss of 2.6 cm obtained for this point. In this point, the 137 Cs activity determined for the 0-2 cm profile was due to the 137 Cs dilution in the adjacent downward layers by the bioturbation (Tyler et al, 2001). The bioturbation in this point was down to 6 cm and the 137 Cs concentration was approximately uniform too, which indicated that 137 Cs dilution had occurred in this profile (0-6 cm).…”

Radiocaesium being very soft, lustrous, and highly reactive metal is very harmful if present in large quantity in the environment. Here in this chapter, we will discuss the contaminated sites and possible remediation methods of radiocaesium just to eliminate from ecosystem and make our planet green and peaceful. Lots of radionuclides released not only to atmosphere but also into the oceans, rivers, lakes, and other water bodies after global fallout, Chernobyl accident, giant tsunami, and Fukushima nuclear power plant accident in 2011. It damaged all the living on terrestrial and aquatic ecosystems. Many attempts have been taken into account to reduce its dangerous effects but still world is facing this enigma. Many polluted sites and treatments have been discussed in detail.

“…As already indicated, any interpretation regarding leaching of 137 Cs may be in error if biological cycling from soil to plant to litter, that effectively reverses the leaching process, is not taken into account. Biological cycling is important for other contaminants as well, for example, Johnson et al (2004) (Tyler et al 2001). markedly slower.…”

“…When pollen from a specific species can be attributed to an event or time period, the presence of the pollen becomes a practical tracer for dating soil processes (Coil et al 2003;Hughes et al 2002). As a specific example, Tyler et al (2001) studied soil bioturbation using three tracers: bomb-test 137 Cs, pollen from non-native trees planted in a nearby arboretum operating since 1840, and spheroidal carbonaceous particles from Industrial Age emissions that also peaked after 1840. Mixing of the pollen and carbonaceous particles with depth was clearly the result of particle movement, and in this case agreed with the 137 Cs migration, corroborating that the migration of 137 Cs was as bound to soil particles.…”

Sheppard, S. C. 2005. Assessment of long-term fate of metals in soils: Inferences from analogues. Can. J. Soil Sci. 85: 1-18. The assessment of the health and environmental impacts of metal contamination in soils is complicated, and in different ways than is the assessment of many other contaminants. One of the foremost problems is that the metals are often relatively immobile, so that it is necessary to verify predictions of mobility and impact far into the future. One approach is to seek analogue information: information from studies that may not have set out to measure attributes related to metal behaviour, but that none the less provide useful insights. One example would be the information on the mobility of natural clays and pedogenic metals such as iron and aluminum in soils. It is well accepted that clay particles will move downward in soils; what is less commonly inferred is that any contaminants associated with the clays will also move downward. For mobility of some metals, this may be a dominant process. Similarly, bioturbation has proven to markedly outpace leaching for many metals. This paper considers analogues related to cesium from bomb-fallout and Chernobyl, other natural radionuclide inputs to the soil, soil pedogenesis, pollen and non-metal industrialage inputs, ancient metal works, and soil fertility management. Related to biological transfers and toxicity, it considers analogy among elements and among biota, and analogy to ecotoxicology of metals to freshwater biota. Where possible, limiting values for parameters of assessment models have been derived. Key words:Terrestrial, leaching, mobility, ecotoxicity, assessment Sheppard, S. C. 2005. Évaluation du sort à long terme des métaux dans le sol : inférences à partir des analogues. Can. J. Soil Sci. 85: 1-18. Évaluer l'incidence des métaux qui contaminent le sol sur la santé et l'environnement n'est pas une tâche facile et les difficultés diffèrent de celles soulevées par l'évaluation de nombreux autres polluants. Un des principaux problèmes a trait à l'immobilité relative des métaux. On doit donc vérifier si les prévisions concernant leur déplacement et leurs incidences se véri-fient très loin dans l'avenir. Une façon d'y parvenir consiste à recueillir des données sur les analogues, bref l'information issue d'études dont l'objet principal n'était pas de quantifier les particularités du comportement des métaux, mais qui nous renseignent néanmoins sur le sujet. Les données sur la mobilité des argiles naturelles et des métaux pédogènes tels le fer et l'aluminium dans le sol en sont un exemple. On sait pertinemment que les particules d'argile s'enfoncent dans le sol, mais on songe moins souvent que les substances contaminant l'argile en font autant. Il pourrait cependant s'agir d'un processus dominant pour la mobilité de quelques métaux. Pareillement, on a prouvé que la bioturbation revêt plus d'importance que la lixiviation pour maints métaux. Dans cet article, l'auteur examine les analogues du césium venant des retombées radioactives de l'incide...
