![]() Phytoremediation Radiocesium Radiotoxicity Soil-plant transfer.Ĭopyright © 2017 Elsevier B.V. Monitoring of contaminated soil therefore has to continue for many decades, and edible plants grown on such soil must continuously be monitored. Inside plants, cesium distributes fast between the different plant organs and cells, but cesium in soil is extremely stable and remains for decades in the rhizosphere. Plants with high uptake potential could be used to remediate soil and water from radiocesium by accumulation and rhizofiltration. We reviewed information about reducing cesium in the vegetation by loss processes, and we extracted transfer factors from the available literature and give an overview over the uptake capacities of 72 plants for cesium from the substratum to the biomass. Cesium has many industrial applications, including the construction of atomic clocks. Some improve desorption of Cs+ from clay minerals, while surfactants and polymers expand the interlayer. Most techniques use ion exchange with acids, cations, polymers, and surfactants. Uptake of cesium occurs also from air through interception and absorption on leaves and from water through the whole submerged surface. It has an atomic symbol Cs, atomic number 50, and atomic weight 132.91. This review summarizes the mechanisms for desorbing and extracting cesium (Cs+) from clay minerals and soil. ![]() In soil, bioavailability of cesium depends on the chemical composition of the soil and physical factors such as pH, temperature and tilling as well as on environmental factors such as soil microorganisms. Uptake of cesium into cells occurs through molecular mechanisms such as potassium and calcium transporters in the plasma membrane. Atlantic Metals & Alloys, LLC has been in business since 1983, supplying metals, chemicals and compounds to the Aluminum Industry, to the Chemical Industry, to. In this review we summarize investigations about sources of stable and radioactive cesium in the environment and harmful effects caused by internal and external exposure of plants to radiocesium. ![]() Plants are at the base of the food chain it is therefore essential to understand the mechanisms of plants for cesium retention and uptake. ![]() It either acts directly on living organisms from external sources, or it becomes incorporated through the food chain, or both. Radiocesium in water, soil, and air represents a severe threat to human health and the environment. ![]()
