“…In our study, water extracted the least Pb with a maximum of about 1% of the total lead which is in agreement with previous results (Houba et al, 1996;Quevauviller, 1998). CaCl 2 extracted the highest amount of Pb with a maximum of about 10% of the total concentration (Fig.…”

a b s t r a c tThis study aimed at assessing the bioavailability and toxicity of lead to Eisenia andrei in shooting range soils representing different land uses (forest, grassland, bullet plot). Soils contained 47e2398 mg Pb/kg dry weight (dw), but also had different pH-CaCl 2 (3.2e6.8) and organic matter contents (3.8e13%). Therefore artificial soils with different pH and organic matter contents and two natural soils were included as control soils. Earthworms were exposed for 28 days and toxicity and uptake of Pb were related to total, water and 0.01 M CaCl 2 extractable and porewater Pb concentrations as well as to soil characteristics. Pb uptake in the earthworms linearly increased with increasing soil concentrations. At >2000 mg Pb/kg dw and pH 3.3e3.5, high earthworm mortality with significant weight loss and complete inhibition of reproduction were recorded. At <1000 mg/kg dw, earthworm reproduction was more related to differences in pH and other soil characteristics than to Pb.

“…To assess available Pb concentrations, soils were extracted with water and 0.01 M CaCl 2 (Houba et al, 1996), while also porewater was extracted. Water and CaCl 2 extraction are typically used to estimate metal bioavailability and may correlate with metal availability to earthworms (Davies et al, 2003b).…”

“…Among these extractants, EDTA (0.1e1 M) and DTPA (0.005 M), either as sodium or ammonium salts, have been proposed because of their ability to form very stable, water soluble and well-defined complexes with a wide range of metal cations (Haq et al, 1980;Chaignon et al, 2003). A 0.01 M CaCl 2 extractant was also proposed because of the similarity between this extractant and the concentration, composition and pH of soil background electrolytes (Houba et al, 1996). Mench et al (1997) reported that both EDTA and CaCl 2 extractable Cd was positively correlated with Cd contents in wheat roots and seeds.…”

An adjusted-RHIZO method was the most promising approach for predicting metal phytoavailability to wheat under field conditions. AbstractPreviously recommended rhizosphere-based method (RHIZO) applied to moist rhizosphere soils was integrated with moist bulk soils, and termed adjusted-RHIZO method (A-RHIZO). The A-RHIZO and RHIZO methods were systematically compared with EDTA, DTPA, CaCl 2 and the first step of the Community Bureau of Reference (BCR1) methods for assessing metal phytoavailability under field conditions. Results suggested that moist bulk soils are equally suited or even better than rhizosphere soils to estimate metal phytoavailability. The A-RHIZO method was preferred to other methods for predicting the phytoavailability of Ni, Cu, Zn, Cd, Pb and Mn to wheat roots with correlation coefficients of 0.730 (P < 0.001), 0.854 (P < 0.001), 0.887 (P < 0.001), 0.739 (P < 0.001), 0.725 (P < 0.001) and 0.469 (P < 0.05), respectively. When including soil properties, other extraction methods were also able to predict phytoavailability reasonably well for some metals. Soil pH, organic matter and FeeMn oxide contents, and cation-exchange capacity mostly influenced the extraction and phytoavailability of metals.

“…In 25 mL polypropylene centrifugation tubes, 10 mL of 10 −2 M CaCl 2 were added to 1.0 g of soil. The liquid to solid ratio of 10 is high enough to avoid samples heterogeneities [38]. After agitation end-over-end during 2 h at 5 rpm at 20 • C, samples were then centrifuged during 30 min at 10,000 × g. Supernatant was sieved through a 0.22 m mesh and acidified at 2% with HNO 3 (15 N, suprapur 99.9%).…”

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.
