“…Multiple endpoints have been established for assessment of risks posed by soil-borne contaminants to organisms directly impacted by them. This report supersedes a prior report on screening benchmarks for phytotoxicity (Suter et al 1993). Benchmarks for toxic effects of contaminants on earthworms and soil microbial processes are presented in a companion manuscript (Will and Suter, 1994).…”

“…These may be explained by the low concentrations observed in the leachates and phytoextracted fraction, which could suggest that pollutants' migration and/or the available fraction was very low. Efroymson et al (1997) developed, for terrestrial plants, a toxicological benchmark for contaminants with a potential concern effect, where the established thresholds were 4 mg Cd•kg −1 , 1 mg Cr•kg −1 , 50 mg Pb•kg −1 , and 30 mg Ni•kg −1 . The concentrations estimated in this work are found to be far from the abovementioned values.…”

Landfills and waste disposal sites in the Basque Country are summarized in the inventory of soils that either currently support or have supported potentially polluting activities or facilities (Law 4/2015). Notably, “Landfill 17,” located in Gernika-Lumo, has been receiving, for decades, sewage sludges from the local wastewater treatment plant (WWTP) as agricultural amendment. In order to decontaminate and recover soil functionality, a combination of bioremediation (which involved bioagumentation and phyto- and vermitechnologies) and complementary bioremediation strategy (i.e., promotion and maintenance of the native vegetation) was implemented in situ. Physicochemical and ecotoxicological characterization were achieved. Furthermore, an ecotoxicological assessment of the soils upon flora and fauna was carried out through the application of different bioassays and biomarkers. Additionally, an integrative biomarker response (IBR/n) index was calculated to provide a holistic view of the soil general status. Critical pollutants [Cd, Cr, Ni, Pb, benzo(a)pyrene, and dieldrin] were observed in most of the treated sites. Microbial parameters did not present remarkable differences among sites. However, plant indicators pointed the non-treated site (MN8) as the unhealthiest. This was also observed in earthworms’ immune system, where cytotoxicity appears when exposed to non-treated soils. In conclusion, this field study showed that the combination of bioaugmentation, phytoremediation with native species, and vermiremediation is highly useful in eliminating mixed contamination, improving soil health, and ultimately restoring ecosystem functionality and biodiversity.

“…Vegetation may be adversely impacted by the deposition of chemical material by-products on plant surfaces or uptake by root systems. Where applicable, contaminant concentrations that result in a measurable reduction in plant growth and yield as calculated by Suter et al (1993) will be presented.…”
