![]() ![]() ![]() “The outcome of the present research should encourage authorities to cultivate S. Jisha, assistant professor of plant science at the MES Asmabi College, Kodungallur, Kerala. “Phytoremediation is widely accepted for eliminating contaminants in the environment because it is eco-friendly and cost-effective, says K.C. “The caesium-137 isotope presents the worst radiation hazards as it can cause infertility and cancer,” he said. Syamchand, who was not a participant in the study, said caesium had 40 isotopes (members of an element’s family having the same number of protons but different numbers of neutrons in the atomic structure). Syamchand, researcher in chemistry and associate professor at the University College, Thiruvananthapuram. The finding that sesuvium is capable of hyper-accumulation of caesium is highly significant says S.S. ![]() The study acknowledges that further studies are required to understand the precise molecular mechanism of caesium tolerance that may depend on the presence of microbes associated with the plant. portulacastrum has been extensively studied for its applicability in phytoremediation of heavy metals such as cadmium, arsenic, lead, nickel and copper,” Nikam tells SciDev.Net. The presence of radiocaesium and other metal toxicants in soil, water and air can cause serious consequences to human health and the environment, says the study, and one way to deal with it is to use plants for “phytoremediation” of soils. Nikam, an author of the study and professor, Department of Botany, Savitribai Phule Pune University, Pune, India. That is why we selected the plant for this study,” says T. “Sesuvium plants rapidly uptake toxic compounds and translocate them to aerial parts such as leaves and stem. “Sesuvium plants rapidly uptake toxic compounds and translocate them to aerial parts such as leaves and stem” T. The study, published October in Advances in Agriculture,described it as a “hyper-accumulator” of caesium and capable of improving soils contaminated by the metal. Sea purslane or Sesuvium portulacastrum is a salt-tolerant, perennial flowering succulent that grows in sandy coastlines around the world. A herb that grows abundantly in coastal areas can be used to rid the soil around nuclear plants of caesium, a radioactive by-product of reactors, says a new study. ![]()
