“…As a consequence, a large number of soil extraction methods have been developed to obtain the bioavailable fraction of metals (for review, see Peijnenburg et al, 2007). Among these, the one-step extraction method of soil with 0.01 M CaCl 2 , which was proposed by Houba et al (1996), has proven to be a very useful indication of metal phytoavailability (Pueyo et al, 2004;Meers et al, 2007;Peijnenburg et al, 2007) and has been used by many different laboratories (Hodson et al, 2000;Gucwa-Przepióra et al, 2007;Menzies et al, 2007;Lopareva-Pohu et al, 2011;Vondrá cková et al, 2014). For this reason, in this study, the concentration of the phytoavailable forms of the HM in the soil samples was assessed by the extraction of 3 g of dry soil that was sifted to pass through a 2-mm sieve with 30 mL of 0.01 M CaCl 2 for 2 h at room temperature.…”

In earlier ecophysiological studies that were conducted on Arabidopsis halleri plants, scientists focused on the mechanisms of Cd and Zn hyperaccumulation but did not take into consideration the environmental factors that can significantly affect the physiological responses of plants in situ. In this study, we investigated A. halleri that was growing on two nonmetalliferous and three metalliferous sites, which were characterized by different environmental conditions. We compared these populations in order to find differences within the metallicolous and nonmetallicolous groups that have not yet been investigated. The concentrations of several elements in the plant and soil samples also were investigated. To our knowledge, the concentration and fluorescence of chlorophyll were measured for A. halleri in situ for the first time. Our study confirmed the hyperaccumulation of Cd and Zn for each metallicolous population. For the metallicolous populations, the inhibition of parameters that describe the efficiency of the photosynthetic apparatus with increasing accumulations of heavy metals in the shoots also was observed. It was found that the nonmetallicolous plant populations from the summit of Ciemniak Mountain had larger antenna dimensions and chlorophyll content but a lower percentage of active reaction centers. To our knowledge, in this study, the internal high physiological diversity within the populations that inhabit metalliferous and nonmetalliferous sites is presented for the first time.

“…All MTE were extracted in substantially equal proportions with water (from 0 to 18%); MTE concentrations in CaCl 2 extracts and corresponding ratios, varied in the range of those reported in the literature [5,58,61], and Cd was the most available element (up to 32%). Extracted concentrations were strongly correlated to total concentrations: R 2 = 0.92 and 0.95 (p < 0.0001), respectively, for water and CaCl 2 .…”

This is an author-deposited version published in : http://oatao.univ-toulouse.fr/ Eprints ID : 11346 a b s t r a c tWith the rise of sustainable development, rehabilitation of brownfield sites located in urban areas has become a major concern. Management of contaminated soils in relation with environmental and sanitary risk concerns is therefore a strong aim needing the development of both useful tools for risk assessment and sustainable remediation techniques. For soils polluted by metals and metalloids (MTE), the criteria for landfilling are currently not based on ecotoxicological tests but on total MTE concentrations and leaching tests. In this study, the ecotoxicity of leachates from MTE polluted soils sampled from an industrial site recycling lead-acid batteries were evaluated by using both modified Escherichia coli strains with luminescence modulated by metals and normalized Daphnia magna and Alivibrio fischeri bioassays. The results were clearly related to the type of microorganisms (crustacean, different strains of bacteria) whose sensitivity varied. Ecotoxicity was also different according to sample location on the site, total concentrations and physico-chemical properties of each soil. For comparison, standard leaching tests were also performed. Potentially phytoavailable fraction of MTE in soils and physico-chemical measures were finally performed in order to highlight the mechanisms. The results demonstrated that the use of a panel of microorganisms is suitable for hazard classification of polluted soils. In addition, calculated eco-scores permit to rank the polluted soils according to their potentially of dangerousness. Influence of soil and MTE characteristics on MTE mobility and ecotoxicity was also highlighted.

“…Indeed, in one hand, FAs were seen to be effective in reducing the mobility of traces metals in soils (LoparevaPohu et al, 2011a) but also in reducing their bioavailability for plants (Pourrut et al, 2011) and for earthworms (Grumiaux et al, 2010). In addition, FAs were shown to be beneficial for the growth of herbaceous species (Lopareva-Pohu et al, 2011b) and to reduce earthworm mortality (Grumiaux et al, 2010). On the other hand, FAs as well as FAs-treated soils were seen to result in negative effects on plants photosynthetic pigments (Lopareva-Pohu et al, 2011b) and on the growth of tree species (Pourrut et al, 2011).…”

“…The absence of avoidance could be explained by a rather low availability of TEs in these highly contaminated soils. For instance, Lopareva-Pohu et al (2011b) indicated for the soils F1 and F2 used in the study that 0.01 M CaCl 2 extractable concentrations of Cd, Zn, and Pb were respectively 10-200, 100-1000 and 25,000-100,000-fold lower than the pseudo total ones. In contrast with the results obtained with the field soils, E. fetida avoided significantly (p o0.01) the control soil M2010 spiked with 0.5 mg Cu/kg dry soil although this concentration was far below those of the field soils tested (between 19 and 29 mg Cu/kg dry soil) but also of the soil background values for northern France (25-30 mg/kg dry soil) (Baize and Sterckeman, 2001).…”
