| description | The production and consumption of surfactants are constantly increasing, and huge amounts are found in the environment as contaminants. Surfactants are widely used in domestic and industrial applications, including in tunnel-mechanized excavation of large-scale infrastructures (e.g. highways and railways). In the latter case, the commercial products are foaming agents containing the anionic surfactant sodium lauryl ether sulphate (SLES). Foaming agents are necessary for enhancing Tunnel Boring Machine-Earth Pressure Balance (TBM-EPB) performance. Consequently, there are SLES concentrations in excavated soils of which large quantities can have harmful effects on biota. SLES toxicity in the aquatic environment is well known; on the contrary, knowledge of its effects on soil organisms is quite limited. In order to better understand SLES ecotoxicity in soil, the standardized bioassay (ISO 14371:2012) with the crustacean Heterocypris incongruens, living in the soil–water interface, was used. The lethal concentrations of standard SLES (LC15: 120; LC50: 140 mg/L, respectively) and of three common commercial products used as foaming agents (LC50 varying from 275 to 3810 mg/L) were evaluated. Subsequently, the crustacean acute and sub-chronic effects (mortality and growth inhibition) were assessed in seven different excavated soils conditioned with various commercial products. In addition, SLES concentrations in each soil and in their soil water extract were also determined. Mortality was not recorded in soils conditioned with foaming agents; however, a growth inhibition (c.a. 61.6 %) was found for soils with a high fine fraction and conditioned with high amounts (≥2 L/m3 soil) of foaming agents. H. incongruens proved to be an appropriate bioassay for assessing the possible effects of high SLES concentrations in soil, especially when this surfactant is bound to soil. |
