Use of ecotoxicity test and ecoscores to improve the management of polluted soils: case of a secondary lead smelter plant

► This article focuses on the use of biotests to improve polluted soil landfilling. ► New bioluminescent bacterial strains genetically modified were tested. ► Calculated ecoscores permit to rank polluted soil samples according to ecotoxicity. ► Results show the relevance of bioassays for polluted soils management. ► Total MTE-concentrations overestimate risks posed by contaminated soils.
