“…In order to summarize in a number the overall test results and to rank the foaming agent ecotoxicity in SIL and MON soils, a toxicity test battery integrated index was applied. The use of a set of biotests is a common practice when seeking an overview of toxicity [61][62][63]. It is interesting to note that the battery index applied was initially designed for the aquatic environment [55] and, for this reason, in this case reflects a highly precautionary scenario that takes into account any possible SLES leaching or run off to water bodies [16,17,27].…”

Mechanized excavation of tunnels with Earth Pressure Balance-Tunnel Boring Machines requires the use of foaming agents. The latter contain the anionic surfactant sodium lauryl ether sulphate (SLES) as the main compound. The re-use as a by-product of excavated soil containing foaming agents (spoil material) can pose a risk for soil and particularly for aquatic ecosystems if they are close to the spoil material final destination site. This work reports the chemical results (SLES residual concentrations) and ecotoxicological effects (battery of five tests) of 28 day-mesocosm studies performed at a tunnelling construction site. The soil mesocosms were set up with two different lithologies, which contained four different foaming agent products at the highest amounts used for excavation. The decrease in SLES concentrations and the ecotoxicological tests were performed in soil and its water extract (elutriate) at different times (0, 7, 14, 28 d). Elutriates were prepared in order to simulate a possible SLES leaching from soil to water. The results showed a decrease in SLES over time and different ecotoxicological responses depending not only on the initial amount of each product, but also on the soil lithology and organism tested (aquatic or terrestrial). This study showed how only site-specific ecotoxicological evaluations can ensure a safe management of the spoil material, making possible the re-use of soil and avoiding production of waste.

“…As such, the present work was conducted to investigate the possible use of a biosolid as a medium that improves soil properties, enhances tomato growth and increases tomato tolerance to Forl, suggesting its potential use as a soil amendment in agricultural land. Based on the results reported by Giannakis et al (2020b), this biosolid, made from municipal sludge produced in a WWTP of Thessaloniki, Greece, showed negligible ecotoxicological concerns.…”

“…In particular, the substrate treatments consisted of two levels of biosolid (-, +), two levels of inoculum (-, +), and 3 peat treatments (peat, peat plus clay soil, peat plus sandy soil). The biosolid properties were described in Giannakis et al (2020b), the clay soil had silt 40%, 30% clay, 30% sand, 2.5% matter, pH 7.9, and the sandy soil had 71% sand, 20% silt, 9% clay, 1.15% organic matter, and pH 8.1. Biosolid, peat and soil mixture of each substrate was inoculated with Forl conidia at a concentration of 10 4 spores/g of the substrate, as described above.…”

Aims: A biosolid made from municipal sludge, acting as an organic fertilizer that enhanced plant growth and crop productivity, was evaluated for its effect on tomato growth and tolerance enhancement against the phytopathogenic fungus Fusarium oxysporum f. sp. radicis-lycopersici (Forl).Methods: Peat and/or two soil types were amended with mixtures of this biosolid (0, 80 and 160 tn/ha) in order to study the growth of tomato plants and their response to Forl, either under controlled conditions or outdoors in a net protected area.Results: The results showed that biosolid addition increased tolerance of tomato plants against the disease. There was also an increase of tomato fresh weight, root weight, stem height and leaf number compared to the Forl-inoculated control soils. Forl, at 5 weeks after tomato transplanting, caused higher disease index on plants grown outdoors in biosolid plus clay soil than in biosolid plus sandy soil, while the opposite occurred under laboratory conditions where higher disease index was recorded on plants grown in peat plus sandy soil than in peat plus clay soil. Conclusions:The ndings strongly support the evidence that this biosolid may act as an organic fertilizer and as a possible stimulant of tomato tolerance against Forl. Therefore, this type of biosolid, previously proven to be minimal ecotoxicological impact, should be considered for its possible use in agriculture according to the principles of circular economy and waste minimization.

“…Some sludge treatments conducted prior to composting often induce negative responses. Of these, Microtox or its equivalent (Vibrio fisheri) appears to be one of the most common test types (e.g., Mantis et al, 2005;Giannakis et al, 2020) among the aquatic standard tests (e.g., Malara and Oleszczuk, 2013;Chiochetta et al, 2014) and the terrestrial plant (e.g., Ramirez et al, 2008;Moreira et al, 2008) and invertebrate tests (e.g., Moreira et al, 2008).…”
