“…Originally located on the outskirts of cities, numerous industrial sites, sometimes abandoned, are now in urban areas and are therefore likely to have environmental and health risks to surrounding populations [1,2]. Currently, rehabilitation of the sites frequently entails excavation of polluted soils [3].…”

“…Excavated soils can thus follow two different ways: landfilling, expensive and energy intensive, or reuse/recycling, integrated to sustainable development. The choice of a specific track mainly depends on total and leachable concentrations of the pollutant in the soil [2]. Among the numerous pollutants observed in urban and peri-urban areas, trace metals are often present in soils [4]; atmosphere emissions by smelters being one of the main anthropogenic source [5,6].…”

“…More precisely, the following two scientific objectives were aimed: (1) what is the pertinence of ecotoxicity tests to assess a more realistic human exposition to contaminated soil leachates? (2) What is the influence of soil physicochemical parameters on MTE mobility and leachates ecotoxicity? Several studies use specific bacteria strain to sense the presence of metals in soils [25][26][27][28], nevertheless, the development of statistical model to understand the link between chemical concentration of compound and bacteria sensors is still on-going work [23].…”

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.

Purpose Most previous studies focused on the metal extraction efficiency of chelant-enhanced soil washing under various operational conditions; however, one of the keys to cost-effective field application is to maintain a high throughput rate (i.e., short washing time) while achieving the treatment objectives. Therefore, this study presented a conceptual model for simulating the kinetic extraction of heavy metals and evaluated its sensitivity analysis to the predetermined parameter values in five soils with different initial metal distributions. Materials and methods The proposed conceptual model considered the initial metal distribution and the respective fast and slow first-order extraction rates as the predetermined input parameters. The sensitivity analysis was conducted by combined and individual variation of the parameter values by fixed percentages. An implicit assumption is that there is no interaction between the metal fractions and the parameters are independent of each other. All other parameters were kept constant. Such systematic testing of the model behaviour in reaction to changes in the input parameters helped us identify the parameters that are more sensitive and require particular attention in the modelling process. Results and discussionIn the sensitivity analysis of combined parameter groups, the fraction of fast extraction ( f ) was linearly and inversely correlated to the required washing time in two stages, in which the correlation was more significant at the lower range of f values. The first-order rate coefficients of fast extraction (k′) and slow extraction (k″) showed a nonlinear and negative relationship with the required washing time. The individual contributions of f i and k i ′ of the three fraction groups were then analysed. Although the fraction group 1 (exchangeable and carbonate) had the highest f i and k i ′ values, their importance was limited by relatively small proportion in the field-contaminated soils. The required washing time for Pb extraction was most sensitive to the fraction group 2 (Fe/Mn oxides).Conclusions The results of this study suggested that model simulations are less sensitive to f 1 and k 1 ′ values of exchangeable and carbonate fractions, which can therefore be considered constant. However, f 2 and k 2 ′ values of the oxide fraction are sensitive parameters and should be prudently justified, or even recalibrated, at different sites.
