“…They indeed strongly affect radiocesium mobility and make it temporarily unavailable to the other components in the ecosystem. It should also be noticed that, contradictory to models on radiocesium leaching, upward mobilization of radiocesium occurs in forest soils (Brückmann and Wolters, 1994;Rafferty et al, 1997;Drissner et al, 1998). It was suggested that it could be explained by radiocesium transport from soil to plant by ECM fungi.…”

This review summarizes current knowledge on the contribution of mycorrhizal fungi to radiocesium immobilization and plant accumulation. These root symbionts develop extended hyphae in soils and readily contribute to the soil-to-plant transfer of some nutrients. Available data show that ecto-mycorrhizal (ECM) fungi can accumulate high concentration of radiocesium in their extraradical phase while radiocesium uptake and accumulation by arbuscular mycorrhizal (AM) fungi is limited. Yet, both ECM and AM fungi can transport radiocesium to their host plants, but this transport is low. In addition, mycorrhizal fungi could thus either store radiocesium in their intraradical phase or limit its root-to-shoot translocation. The review discusses the impact of soil characteristics, and fungal and plant transporters on radiocesium uptake and accumulation in plants, as well as the potential role of mycorrhizal fungi in phytoremediation strategies.

“…Numerous publications considering the soil-to-plant transfer report a strong dependence of TF on the soil characteristics, such as soil clay content, NH 4 C concentration and organic matter content (Absalom et al, 2001;Roca et al, 1997;Askbrant and Sandalls, 1998), as well as an effect from the biotransformation processes in the soil (Drissner et al, 1998).…”

“…Although clay content is an inherent feature of soils, their organic matter content levels are directly influenced by agronomic factors such as tillage frequency (Sawhney, 1972). Several experiments were carried out to determine whether two factors, soil organic mater content and mycorhizal infection, had a marked effect on plant accumulation (Drissner, 1998). AM fungi responded to pH in a highly variable fashion.…”

Availability of radiocasium in plant from soil: facts, mechanism and modelling

Radiocaesium is an isotope that can enter the food chain after having been absorbed by plants from soil. Our ability to predict the consequences of an accidental release of 137 Cs depends mainly on the level of understanding of the mechanisms involved in 137 Cs interactions with different components of agricultural and natural ecosystems and their formalization into predictive models. In this study the impact of some environmental and physiological factors, such as root density and presence of AM (Arbuscular mycorrhizal) fungal hyphae, on the ability of plants to uptake and accumulate radiocaesium through the roots was investigated. Three plant species were used: pea, soybean and oats. Experimental data suggested that, as roots explore new volumes of soil during growth, the plant will continue to accumulate this radionuclide at high rates in the early stages of ontogenesis. If plants are established on a contaminated site they may not be able to remove all of this radionuclide from soil, especially if a substantial amount of the radionuclide has been leached below the root zone which is commonly 30-40 cm in depth. Laboratory experiments indicate that certain plants may be able to remove radionuclides, especially 137 Cs, from soil over a time period of 5-20 years.
