“…Regarding terrestrial fauna, PE and PS (0-20% d.w.) significantly increased the activity of detoxifying enzymes (POD and CAT) but reduced that of SOD and GST in earthworms (Eisenia fetida), using MP amounts that generally do not occur in natural conditions [77]; similar results and conclusions were reported by Rodriguez-Seijo et al [78]. Conversely, Sun et al [79] did not evidence a significant modification of the antioxidant defence system and MDA content in earthworms exposed both at low and high MP concentrations (300 and 3000 mg kg −1 ) in soil; similar conclusions were reached by De Felice et al [80] for the giant snail (Achatina reticulata) receiving a diet containing PE-terephthalate. On the other hand, the exposure to MPs modified the oxidative response in the liver, gut, and kidney of mice with increased GPx and SOD and decreased CAT.…”

Micro- and nanoplastics (MPs/NPs) are among the most widely distributed pollutants in the environment. It has been suggested that exposure to MPs/NPs can trigger toxicity pathways among which inflammation and oxidative stress (OS) play a pivotal role. Once absorbed, MPs/NPs may act locally or access the bloodstream and, following the translocation process, reach several organs and tissues, including the gonads. Notably, MPs/NPs can bioaccumulate in human and murine placenta, opening new scenarios for toxicological evaluations. We review recent studies on the effects of MPs/NPs on the reproductive health in aquatic and terrestrial organisms of both sexes, focusing on the role of OS and the antioxidant defence system failure as the main underlying mechanisms. Alterations in gametogenesis, embryonic and offspring development, and survival have been shown in most studies and often related to a broken redox balance. All these detrimental effects are inversely related to particle size, whereas they are closely linked to shape, plastic polymer type, superficial functionalization, concentration, and time of exposure. To date, the studies provide insights into the health impacts, but no conclusions can be drawn for reproduction toxicity. The main implication of the few studies on antioxidant substances reveals their potential role in mitigating MP-induced toxic effects.

“…Cheng et al (2020) also observed that the combined exposure of LDPE and atrazine resulted in higher levels of atrazine in earthworms than their single exposures. Sun et al (2021) obtained similar results for the combined exposure of earthworms using MPs and dufulin. However, MPs did not always enhance the bio-efficacy of other contaminants in earthworms.…”

Accumulation of microplastics (MPs) in soil is a serious environmental concern. Addition of exogenous MPs can alter structure and physicochemical properties of and material transport in soil. MPs are particularly toxic to earthworms, which are soil ecosystem engineers, and exacerbate ecological risks; however, there is a lack of comprehensive and in-depth analyses of how MPs exhibit toxicity to/towards earthworms. In this study, we report a bibliometric analysis of 77 peer-reviewed papers published before December 2021 to systematically analyze how the addition of exogenous MPs contributes to earthworm toxicity and clarify the historical development and research hotspots in this field. We found that first, polyethylene and polystyrene are the most common materials used to study the toxic effects of MPs on earthworms. Second, the toxic mechanisms of MPs on earthworms mainly involve histopathological damage and oxidative stress, as well as serving as carriers of complex pollutants (e.g., heavy metals and organic pollutants) through combined adsorption–desorption. Third, oxidative stress is the typical reaction process of MPs toxicity in earthworms. When the content of MPs in soil exceeds 0.1%, earthworm growth is affected, and oxidative stress is induced, resulting in neural and DNA damage. Based on published studies, the prospects for future research on the ecological risks posed by MPs to earthworms have also been discussed. Overall, our findings help clarify the ecological risk of soil MPs toxicity to earthworms, reveal the mechanism of their toxic effects, and provide a theoretical basis for future studies focusing on establishing a healthy and ecologically sustainable soil environment.

“…There was a consistent dosage response pattern of MDA content in earthworms, as shown in Figure 8 , with the peak occurring after 28 days of incubation. The fact that MDA levels in earthworms exposed to the pollutant suggest that the organisms were damaged by excessive ROS ( Sun et al., 2021 ), as shown in Figure 8 . After exposure to AgNPs and AgNO 3 , it was established that ROS production followed a clear dose-dependent pattern.…”

“…growth and survivability, uptake and reproduction rate. There are a number of reasons why AgNO 3 might be more hazardous than AgNPs specifically, a) AgNO 3 have a much higher solubility than AgNPs because AgNO 3 is a salt, even though AgNPs are reflected to be a base that customs a colloidal solution in water; b) AgNO 3 have a higher molarity than an equal mass of AgNPs; c) Ag accumulates in cellular membranes from AgNPs, but silver ions are contained by the cytosolic fraction ( Sun et al., 2021 ) and d) Ag from AgNPs showing a higher rate of elimination than AgNO 3 .…”
