“…This alters the plant membrane fluidity, resulting in lower membrane permeability at low temperatures and lower metal uptake (Marschner 1995). Several studies of plants grown at high root temperatures found higher uptakes of zinc (Zn), lead (Pb), cadmium (Cd), silver, chromium and antimony than was the case with plants grown at low root temperatures (Macek et al 1994;Baghour et al 2001;Albrecht et al 2002). These studies indicated that temperature could have indirect effects on plant growth, and also on species relationships, by affecting the availability and accumulation of trace elements in the soil and the plant.…”

A simulated warming manipulation was conducted to evaluate the effects of temperature increase on cadmium (Cd), lead (Pb), copper (Cu), iron (Fe) and zinc (Zn) accumulation in Solanum tuberosum L. at Dingxi, Gansu, in the semiarid northwest of China. The objective of this study was to determine if temperature increases significantly changed trace element concentrations and contents in the different ecosystem compartments by affecting soil content, soil solubility and plant capture. The results reveal that an increase in temperature will lead to a significant change in trace element concentrations and contents in Solanum tuberosum L. The strongest effects of a 3°C temperature increase are increased Cu, Zn and Fe leaf concentrations of 25, 27 and 24%, respectively; but decreases in Cd, Pb, Fe, Zn and Cu tuber concentrations of 27, 55, 41, 29 and 23%, respectively. The increasing concentrations of some trace elements in Solanum tuberosum L. leaves are related to greater retranslocation, photosynthetic capacity and growth. Warming decreases the concentrations of some trace elements in tubers, implying that tuber growth rate exceeds its metal uptake rate at higher temperatures. Indeed, it is expected that by the year Climatic Change (2012) 112:655-672 2050 the increased temperature will have induced a decrease of concentrations of Cd, Pb, Cu, Fe and Zn of 9.1, 11.5, 18.5, 16.8 and 15.8%, respectively, in tubers in the study area. In addition, the results indicate that a 1-3°C increase in temperature will improve the availability of selected trace elements and transfer potential of these elements from soil to Solanum tuberosum L.

“…The concentrations, mobility, and bioavailability of radionuclides depend upon several factors. These include the quality, quantity and the rate of release of radionuclides present at the source; hydrological factors, like dispersion, advection, and dilution; geochemical processes, such as complexation at aqueous phase, pH, adsorption/desorption, solid/liquid distribution coefficient, reduction/oxidation (redox), ion exchange, precipitation/dissolution, diffusion, colloid-facilitated transport, exchangeable potassium ion distribution, anion exclusion and organic matter contents (Albrecht et al 2002;Napier et al 2012;Chakraborty et al 2013;Hegazy et al 2013). Absorption and distribution of contamination in plants may take place either through direct (exposures at aerial organs like leaf, stem, and tendrils) or indirect (through root systems in soil related contamination) routes, which varies considerably in different plant species especially in case of long-lived radionuclides (Din et al 2010).…”

Application of radioactive elements or radionuclides for anthropogenic use is a widespread phenomenon nowadays. Radionuclides undergo radioactive decays releasing ionizing radiation like gamma ray(s) and/or alpha or beta particles that can displace electrons in the living matter (like in DNA) and disturb its function. Radionuclides are highly hazardous pollutants of considerable impact on the environment, food chain and human health. Cleaning up of the contaminated environment through plants is a promising technology where the rhizosphere may play an important role. Plants belonging to the families of Brassicaceae, Papilionaceae, Caryophyllaceae, Poaceae, and Asteraceae are most important in this respect and offer the largest potential for heavy metal phytoremediation. Plants like Lactuca sativa L., Silybum marianum Gaertn., Centaurea cyanus L., Carthamus tinctorius L., Helianthus annuus and H. tuberosus are also important plants for heavy metal phytoremediation. However, transfer factors (TF) of radionuclide from soil/water to plant ([Radionuclide]plant/[Radionuclide]soil) vary widely in different plants. Rhizosphere, rhizobacteria and varied metal transporters like NRAMP, ZIP families CDF, ATPases (HMAs) family like P1B-ATPases, are involved in the radio-phytoremediation processes. This review will discuss recent advancements and potential application of plants for radionuclide removal from the environment.

“…Grains are subjected to contamination during storage and if fall out occurs during the growing season and in the soil. Radionuclide will be transported into grains through the plant growth process (Albrecht et al, 2002). Naturally occurring Radionuclide (NORM) of Thorium and Uranium are significant contribution of ingestion dose and are present in the biotic systems of plants, animals, soil, water and air.…”

Abstract:The gross alpha and beta radio activity concentration in tubers and cereals obtained in selected oil fields within the Niger Delta Region of Nigeria have been studied and evaluated. Tubers and cereals samples were harvested, collected and analyzed for gross alpha and beta activity using an IN-20 model gas-flow proportional counter. The results obtained showed that the average gross alpha and beta activity for tuber samples ranged from BDL to 0.294±0. 0391 and BDL to 0.293± 0.053 Bq/g respectively, while the average gross alpha and beta activity for cereal samples ranged from BDL to 0.087± 0.040Bq/g and BDL to 0.414.±0.040 Bq/g respectively. These results revealed an elevation over the activity of the control samples taken from non-oil bearing environment and the World Health Organization standard limit of 0.1 Bq/g for gross alpha activity but the average beta activity were all below the WHO standard limit of 1.0Bq/g in all the zones studied. The elevation recorded may be due to oil exploration activities with associated artificial or anthropogenic activities such as gas flare, pollutants, transportation by air media to plant surfaces, frequent oil spillage into and back to the soil or any accidental underground pollutants into the food chain encountered in the surveyed areas. However, the results so obtained may not pose any serious detrimental health side-effects to the public consuming these products.
