“…Instead of these tests, experiments by using bacterial strains allowed to determine and quantify the element which was potentially bioavailable and/or toxic for bacteria [50]. Then, response in ecotoxicity tests was not always directly correlated with total or water-soluble concentrations [65]. These results are in agreement with data previously obtained by Plaza et al [14] concerning the influence of pH and CEC on MTE behaviour in soils.…”

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.

“…Lettuce is used for toxicity assessment in moderate pH environment (pH 6-8) (ISO 2005b;Sheppard et al 1993;Chapman et al 2010Chapman et al , 2012 because it is not a good acid-tolerant species (Chapman et al 2012;Environment Canada 2005). Among higher plants, oat is recommended for toxicity tests of heavy metals (Chang et al 1997;ISO 2005a) under low pH conditions (Loureiro et al 2006;Small and Jackson 1949;Bilski and Foy 1987), while Allium cepa is Pb tolerant in acidic environment (Dang et al 1990).…”

Heavy metal contamination is a globally recognized environmental issue, threatening human life very seriously. Increasing population and high demand for food resulted in release of various contaminants into environment that finally contaminate the food chain. Edible plants are the major source of diet, and their contamination with toxic metals may result in catastrophic health hazards. Heavy metals affect the human health directly and/or indirectly; one of the indirect effects is the change in plant nutritional values. Previously, a number of review papers have been published on different aspects of heavy metal contamination. However, no related information is available about the effects of heavy metals on the nutritional status of food plants. This review paper is focused upon heavy metal sources, accumulation, transfer, health risk, and effects on protein, amino acids, carbohydrates, fats, and vitamins in plants. The literature about heavy metals in food plants shows that both leafy and nonleafy vegetables are good accumulators of heavy metals. In nonleafy vegetables, the bioaccumulation pattern was leaf > root ≈ stem > tuber. Heavy metals have strong influence on nutritional values; therefore, plants grown on metal-contaminated soil were nutrient deficient and consumption of such vegetables may lead to nutritional deficiency in the population particularly living in developing countries which are already facing the malnutrition problems.

“…In recent years, the risk assessment process used for determining the need for remediation or redevelopment actions at contaminated sites has become well developed [51,6] and documented [68,69,43]. Although large amounts of toxic substances may be of major concern, simply detecting a hazardous chemical in the environment should not necessarily be a cause of alarm, depending on the chemicals' bioavailability and the risk of human exposure.…”
