“…These authors also reported concentration-dependant increases in enzyme activities. In another study with AgNPs, Gomes et al [49] reported oxidative damage for higher doses (0, 100, 300, 600, 1000, 1500 mg/kg) and exposure times (4 days vs. 28 days) in Eisenia fetida. Induction of oxidative stress and antioxidant enzymes by titanium oxide NP (TiO 2 NP) in Daphnia magna was studied by Kim et al [34].…”

Nanotoxicology represents a new and growing research area in toxicology. It deals with the assessment of the toxicological properties of nanoparticles (NPs) with the intention of determining whether (and to what extent) they pose an environmental or societal threat. Inherent properties of NPs (including size, shape, surface area, surface charge, crystal structure, coating, and solubility/dissolution) as well as environmental factors (such as temperature, pH, ionic strength, salinity, and organic matter) collectively influence NP behavior, fate and transport, and ultimately toxicity. The mechanisms underlying the toxicity of nanomaterials (NMs) have recently been studied extensively. Reactive oxygen species (ROS) toxicity represents one such mechanism. An overproduction of ROS induces oxidative stress, resulting in inability of the cells to maintain normal physiological redoxregulated functions. In the context of this book, this chapter includes topics pertaining to chemical and physical properties of NMs and characterization for proper toxicological evaluation, exposure, and environmental fate and transport, and ecological and genotoxic effects. This chapter reviews the available research pertaining specifically to NMs in the aquatic environment (in plants, aquatic invertebrates, and fish) and their use in biomarker studies.

“…Dissolved Ag from NPs was responsible for toxicity in the earthworms E. fetida and E. andrei (Schlich et al, 2013;Tsyusko et al, 2012), the collembolan F. candida (Waalewijn-Kool et al, 2013), and the nematode Caenorhabditis elegans (Meyer et al, 2010). Even though a particle effect was suggested, toxicity still was mainly related to ionic Ag for the potworm Enchytraeus albidus (Gomes et al, 2013) and the earthworm E. fetida (Gomes et al, 2015). …”

“…This agrees with our present study, which found a >2‐fold increase in CAT activity by Ag + . Gomes et al (2015) showed that exposure of E. fetida to Ag + mixed in Organisation of Economic Co‐operation and Development soil spiked with 25 to 200 mg/kg for 28 d resulted in increases in GPx, SOD, and GR by 300, 100, and 200%, respectively, but reduced the activities of CAT and GST. These findings in earthworms exposed to very high concentrations are somewhat dissimilar to our much lower dose 4‐wk study, where we observed a continued increase of all antioxidant enzymes up to 4 wk.…”

“…These findings in earthworms exposed to very high concentrations are somewhat dissimilar to our much lower dose 4‐wk study, where we observed a continued increase of all antioxidant enzymes up to 4 wk. Gomes et al (2015) used E. fetida (whereas we used A. caliginosa earthworms) and high doses of Ag + up to 200 mg/kg and uncapped AgNPs up to 1500 mg/kg, which could be considered unrealistic environmental concentrations. Such high concentrations can lead to marked irreversible enzymatic and metabolic changes.…”

Silver nanoparticles (AgNPs) from industrial use, discharged via the land application of sewage sludge, are interacting with soil biota, including earthworms. In affected organisms, excessive production of reactive oxygen species can result in lipid peroxidation, shifting the balance between oxidants and antioxidants to cause oxidative stress. We determined selected lower‐tier biomarkers such as antioxidant responses and lipid peroxidation in Aporrectodea caliginosa earthworms exposed to soils spiked with AgNPs or silver nitrate (AgNO3). Aporrectodea caliginosa were exposed to AgNPs at 0 (control), 0.3, 3, 30, and 300 mg/kg or Ag+ (as AgNO3) at 0, 0.03, 0.3, 3, and 10 mg/kg in soil for 4 wk. At 1, 2, 3, and 4 wk, the activity of the antioxidant enzymes superoxide dismutase, catalase, glutathione peroxidase, glutathione S‐transferase, as well as lipid peroxidation (malondialdehyde content), increased as a function of concentration, with a much larger response for Ag+ than AgNPs. Given the likelihood of ever‐increasing AgNP concentrations in soil, where AgNPs can transform to ionic Ag (Ag+), our findings of antioxidant response to oxidative stress in a common indicator organism even at an environmentally realistic exposure concentration of 0.03 mg/kg demonstrate that AgNPs may affect soil fertility and, thus, agricultural production. Evaluating selected lower‐tier biomarkers offers a meaningful assessment of AgNPs and Ag+ effects on terrestrial earthworms. Environ Toxicol Chem 2020;39:1257–1266. © 2020 SETAC
