“…In addition, earthworms are frequently used in the determination of soil quality, taking into account their ability to accumulate different environmental xenobiotics (Marinussen et al 1997). Earthworms also participate in the bioremediation of contaminated soils (Zapata et al 2016;Barbaran 2017). The effect of these contaminating substances will depend in part on their bioavailability, the degree of biotransformation into substances of lower toxicity and their elimination (Viswanhathan 1994).…”

Purpose: Bovine and equine faeces are commonly used to produce vermicompost of Eisenia foetida earthworms as a soil fertility enhancer. In animal health, ivermectin (IVM) is frequently used for parasite control. However, IVM is eliminated mainly by faeces, which raises environmental concerns. Little is known about the transfer of IVM by the earthworms´ activity. In this work the accumulation of IVM in E. foetida worms cultured in vermicompost containing IVM and the ability of the worms to release IVM to a drug-free substrate were evaluated. Methodology: The acute toxicity test (72 h) of IVM and two bioassays, accumulation (A) and elimination (B), with E. foetida earthworms were performed in the current work. In A, the vermicompost produced was a mixture of equine and bovine faeces, the latter added with IVM 3,000 ng/g. Worms and substrates were sampled between 1 and 28 days post treatment (dpt). In B, worms obtained at 28 dpt in A were transferred to a substrate without IVM and sampled between 1 and 14 days later. Samples of worms and substrates were analysed using High Performance Liquid Chromatography (HPLC). Findings: There was no worm mortality in the toxicity test. In assay A, E. foetida worms bio-accumulated up to 26.8% of the IVM present in the substrate. When worms from assay A, were moved to IVM-free substrate, they released 84% of the bio-accumulated IVM during the first day. Recommendations: This study highlights that IVM bio- accumulated by earthworms and releasing in residue-free substrates represents a contamination risk, especially in farms that are minimising the use of chemical compounds.

“…For further studies, we propose to evaluate the biochemical responses of Eisenia fetida to the hydrogel through soil exposure tests, which in addition to allowing us to study the chronic effects derived from exposure and ingestion will provide information on the dynamics of the microbial community [ 71 ], changes in the ability of earthworms to form galleries, and agitation and removal of the pollutant in the soil [ 72 ]. For the characterization of the oxidative stress mechanisms generated in the earthworms due to exposure to the hydrogel, the quantification of a battery of enzymes involved in oxidative stress is contemplated.…”

Hydrogels are polymers of great importance due to their multiple applications, which have led to an exponential increase in their production. However, once they have fulfilled their function, they become waste and their ecotoxicological effects are unknown. The aim of the present study was to evaluate the acute toxicity and total antioxidant capacity of the earthworm (Eisenia fetida) exposed to a terpolymeric hydrogel (acrylic acid, acrylamide, and 2-acrylamido-2-methyl-1-propane-sulfonic acid) crosslinked with modified kraft lignin. Four different amounts of hydrogel per unit area were evaluated (0.0924, 0.1848, 0.9242, and 1.848 mg hydrogel/cm2) plus a control, and three replicates were performed for each group. Starting from the amount of 0.1848 mg hydrogel/cm2, the earthworms showed physiological and behavioral alterations; at higher amounts, 0.9242 and 1.848 mg hydrogel/cm2, more acute signs were observed with mortality rates of 51.7% and 100%, respectively. On the other hand, the antioxidant activity assay showed that the higher the hydrogel exposure amount, the higher the oxidative stress, as evidenced by lower antioxidant activity (67.09% inhibition of the ABTS●+ radical). Therefore, we concluded that the lignin-modified hydrogel generated oxidative stress and acute lethal toxic effects in Eisenia fetida.

“…It is also known that through their mucilaginous secretions and transformation of organic material, worms increase the activity of microorganisms and the availability of nutrients. Likewise, it has been reported that worms can stimulate bacteria, fungi, and other species related to the degradation of some organic pollutants (Zapata et al 2017).…”

Pesticides containing organophosphorus compounds, such as chlorpyrifos (CPF), are frequently used in agricultural activities, and their use has been increasing due to the presence of multiple plant diseases which threaten the production of vegetable food products. As a result of this practice, the soils in question are often found to be contaminated due to the fact that these pesticides do not immediately degrade and hence remain for long periods of time. The objective of this study was to evaluate the degradation of CPF in the presence and absence of the worm Eisenia foetida (EF) in soils contaminated with 40 mg/kg of CPF during a 28-day period. The D group, whose soil was sterilized and in which no EF worms were present, yielded a CPF-degradation result of 33.68 %. The C group, in which the soil was unsterilized and there were no EF worms present, yielded a degradation percentage of 37.16 %. On the other hand, the B group, containing sterilized soil in which the EF worms were present, yielded a degradation percentage of 60.76 %. Finally, with the A group, in which the soil was unsterilized and EF worms were present, degraded in 74.85 %. Eisenia foetida (EF). En el grupo D, cuyo suelo estaba esterilizado y en ausencia de EF, se obtuvo una degradación del CPF de 33.68 %. En el grupo C, donde el suelo no estaba esterilizado y en ausencia de EF, se obtuvo un porcentaje de degradación de 37.16 %. Por otro lado, el grupo B, que contenía suelo esterilizado en presencia de EF, mostró un porcentaje de degradación de 60.76 %. Finalmente, el grupo A, cuyo suelo no estaba esterilizado y en presencia de EF, se degradó en un 74.85 %.
