“…However, for plants, differences were observed in the different elements, indicating that the absorption capacity depends on the elements and plant species. The lowest BCF values were obtained for As in the three plant species wheat (0.0920.077), radish (0.260.26), and vetch (0.0510.054), according with the values measured by Anawar et al (2006). Moreover, these results are consistent with the literature (Smith et al, 2008), which shows that radish exhibits a certain ability to transport arsenic to aerial tissues 3.4.…”

El acceso a la versión del editor puede requerir la suscripción del recurso AbstractThe interactions and relevance of the soil (total and available) concentrations, accumulation, and acute toxicity of several essential and non-essential trace elements were investigated to determine their importance in environmental soil assessment. Three plant species (T. aestivum, R. sativum, and V. sativa) and E. fetida were simultaneously exposed for 21 days to long-term contaminated soils collected from the surroundings of an abandoned pyrite mine. The soils presented different levels of As and metals, mainly Zn and Cu, and were tested at different soil concentrations (12.5, 25, 50, and 100% of contaminated soil/soil (w/w)) to increase the range of total and available soil concentrations necessary for the study. The total concentrations in the soils (of both As and metals) were better predictors of earthworm uptake than were the available concentrations. In plants, the accumulation of metals was related to the available concentrations of Zn and Cu, which could indicate that plants and earthworms accumulate elements from different pools of soil contaminants. Moreover, Zn and Cu, which are essential elements, showed controlled uptake at low concentrations. The external metal concentrations predicted earthworm mortality, whereas in plants, the effects on growth were correlated to the As and metal contents in the plants. In general, the bioaccumulation factors were lower at higher exposure levels, which implies the existence of auto-regulation in the uptake of both essential and non-essential elements by plants and earthworms.

“…Our results show that the activity concentration of 226 Ra was higher in all three plant species and the highest, as expected, in Juncus effusus, which is known to accumulate toxic metals [18][19][20]. Molinia arundinacea contained the lowest activity concentration of 230 Th.…”

Although the influential area of the former uranium mine ať Zirovski vrh, Slovenia has been under continuous radiological monitoring, more detailed radioecology studies, focused on assessing mobility and bioavailability of deposited radionuclides, were initiated about five years ago. The mobility of 238 U, 234 U, 230 Th and 226 Ra was studied applying two sequential extraction protocols. The results revealed that both sequential extraction protocols are not comparable as the data obtained are protocol-and radionuclide-dependent. It was found that the most mobile ones were uranium isotopes, followed by 226 Ra and 230 Th. In addition, uptake of particular radionuclides by the wetland plants (Molinia arundinacea, Juncus effusus and Caltha palustris) grown in soils contaminated with seepage waters from the tailings was studied. The plants contained higher levels of 238 U, 226 Ra and 230 Th compared to the plants from the control site. Activity concentration of 226 Ra was the highest for all three plant species. Activity concentration of natural radionuclides in milk collected from the area ofŽirovski vrh was comparable to the reference location, except for uranium where the content was higher. The combined annual effective dose for adults consuming milk from theŽirovski vrh area is 13 ± 2 μSv yr −1 . *

“…The total concentration of trace elements in the tailings and soil samples (Table 2) is high and within the same range as that given for contaminated soils from the Spanish Pyrite Belt studied by Anawar et al (2006) and Buján et al (2006). Silver (Ag), chromium (Cr), mercury (Hg), tin (Sn), and iron (Fe) concentrations in most of the tailing samples are higher than the maximum allowable value for soils (CCME 1997;Jianguang et al 2007).…”

The study was conducted to characterize mineralogical and elemental composition of mine tailings in order to evaluate the environmental hazards, and identify the metal accumulation potential of native plant species from São Domingos mine, one of the long-term activity mines of the Iberian Pyrite Belt dating back to pre-Roman times. The mine tailings including soils and different plant species from São Domingos were analyzed for determination of tailings characteristics and chemical element contents in tailings and plants. The large amounts of mining wastes are causing significant adverse environment impacts due to acid mine drainage production and mobilization of potentially toxic metals and metalloids in residential areas, agricultural fields, downstreams, and rivers. The typical mineralogical composition is as follows: quartz, micas, K-feldspar, olivine-group minerals, magnetite, goethite, hematite, jarosite, and sulfides. The mine tailings were highly contaminated by As, Ag, Cr, Hg, Sn, Sb, Fe, and Zn; and among them, As and Sb, main contaminants, attained the highest concentrations except Fe. Arsenic has exhibited very good correlations with Au, Fe, Sb, Se, and W; and Sb with As, Au, Fe, Se, Sn, and W in tailings. Among the all plant species, the higher concentrations of all the metals were noted in Erica andevalensis, Erica australis, Echium plantagium, and Lavandula luisierra. Considering the tolerant behavior and abundant growth, the plant species Erica australis, Erica andevalensis, Lavandula luisierra, Daphne gnidium, Rumex induratus, Ulex eriocladus, Juncus, and Genista hirsutus are of major importance for the rehabilitation and recovery of degraded São Domingos mining area.
