“…Native plant species and populations, growing in metalliferous or contaminated sites, are able to cope with the high metal levels present in these soils; for this reason, they are much more resistant to these conditions than other plants and can be used for reclamation purposes [46]. Singh et al [47] analyzed native plants growing on a site near the Uranium mine tailing ponds in Jaduguda and Turamdih, in the Jharkand State (eastern India), contaminated with heavy metals (Al, V, Ni, Cu, Zn, Fe, Co, Se, Mn) and radionuclides. Among the plants able to accumulate toxic metals and remediate the contaminated site, the As hyperaccumulator Pteris vittata was identified as the most versatile as it could accumulate Al, V, Ni, Co, Se, and U. Barrutia et al [48] identified and characterized native plants spontaneously growing on soils from an abandoned Pb-Zn mine containing toxic levels of Cd, Pb, and Zn in the Basque Country (northern Spain).…”

Mineral nutrition of plants greatly depends on both environmental conditions, particularly of soils, and the genetic background of the plant itself. Being sessile, plants adopted a range of strategies for sensing and responding to nutrient availability to optimize development and growth, as well as to protect their metabolisms from heavy metal toxicity. Such mechanisms, together with the soil environment, meaning the soil microorganisms and their interaction with plant roots, have been extensively studied with the goal of exploiting them to reclaim polluted lands; this approach, defined phytoremediation, will be the subject of this review. The main aspects and innovations in this field are considered, in particular with respect to the selection of efficient plant genotypes, the application of improved cultural strategies, and the symbiotic interaction with soil microorganisms, to manage heavy metal polluted soils.

“…This coefficient assumes that all photons that interact are removed and ignores compton scatter and pair production photons (underestimates the shielded dose rate and the shielding required) (Kolupaev et al, 2014). It is also known as narrow beam conditions because the source and detector are assumed to be collimated and the measurement made at a short distance (Laxman Singh et al, 2014).…”

Contamination of environment by radionuclides in territories under urboecosystem conditions is actual problem. The search of new express methods for radioactivity determination of environment is important task of research. In present work it was shown that mosses are bioindicators of radioactive contamination, because they accumulate radioactive substances in high concentrations. Using of bryoindication methods are promising techniques for the assessment of the contamination of ecosystems with radionuclides. The use of epiphytic mosses is the most efficient technique for assessing the contents of radionuclides in the surface air layer. The epiphytic moss (Pylaisia polyantha) growing in different zones of the city of Rostov-on-Don, was used for the radioactivity biomonitoring of urbosystems. The accumulation features of radionuclides in the epitaphic pylaisiella moss (Pylaisia polyantha) in the territory of the city of Rostov-on-Don have been considered. It was shown that Pylaisia polyantha is effective indicator of radioactivity for biomonitoring. The activity concentration of 137 Th were revealed. These were primarily the zones with both industrial and traffic loads and the motor transport zones. The results of investigation showed that the epiphytic moss (Pylaisia polyantha) can be used as indicator of radioactivity pollution in different polluted zones.

Properties of the mine waste represented the toxic nature to human health and may pose numerous risks to the local environment. Although the recorded radioactivity level in these tailings is very low, but to avoid any long term effect of these tailings on the atmosphere as well as native living things, the tailings need to cover with soil. This reduces gamma radiation and radon emission levels. However, to consolidate the radioactivity and remediate the contaminants in the tailings on a sustainable basis, the area needs to be revegetated by candidate plants. Remediation of heavy metal-contaminated sites using plants presents a promising alternative to current methodologies. Therefore, the study was to evaluate the ex-situ phyto-remediation of uranium mine tailing ponds by amending with land soil followed by invading to grow predominant native plant species. Three volumes of the pot culture experiment were carried out i.e. additions of land soil to mine tailing at 0, 50, and 100 percent by volume with four abundance plant species of S. spontaneous (terrestrial), P. vittata (fern) and T. latifolia and C. compressus (aquatic species) were selected in the study. After appropriate preparation U, Mn, Fe, V, Ni, Cu and Zn which were the major contaminants and the pH and EC in soil fractions and also growth parameters in plant materials were analyzed at five stage intervals in the duration of four months. The addition of soil was found significant change in pH to alleviate the toxic effects that heavy metals have on plant health, hence the enhanced growth and survivability was reached. Even while redistributing metals to a less available form, during the remediation the plant species have the capabilities to accumulate substantial amount of toxic metals. The metal concentrations in the plants were found in the order Fe50.92 > Mn7.22 > Zn0.94 > Cu0.92 > Ni0.65 > V0.18 > U0.07 and accumulated in the order Zn0.021 > Cu0.019 > Mn0.014 > Ni0.013 > U0.002 > V0.001 > Fe0.001. The results of the study indicate that C. compressus and S. spontanium were found to be the candidate species for Phyto-remediation (i.e. either accumulation and non-accumulation or consolidation respectively) of contaminants in soil amended Uranium mine tailings. For maximum accumulation, C. compressus harvesting need to be done at after the fourth month of plantation and for consolidation, S. spontanium plantation was greatly recommended. It also confirms that the land soil could be the best amendment for remediation of abandoned mine waste.
