“…Likewise, negative effects on earthworms were often detected in soils treated with biochar (Brtnicky et al 2021). Microplastic particles and fibers have been shown to result in negative fitness effects such as increased mortality, an increase in the production of stress markers, reduced reproductive output, or reduced activity in several studies (Chen et al 2020; Cheng et al 2021; Huerta-Lwanga et al 2021; Jiang et al 2020; Lahive et al 2021; Prendergast-Miller et al 2019; Rodriguez-Seijo et al 2018; Rodriguez-Seijo et al 2017).…”

Terrestrial ecosystems are exposed to many anthropogenic pollutants. Non-target effects of pesticides and fertilizers have put agricultural intensification in the focus as a driver for biodiversity loss. However, other pollutants, such as heavy metals, particulate matter, or microplastic also enter the environment, e.g. via traffic and industrial activities in urban areas. As soil acts as a potential sink for such pollutants, soil invertebrates like earthworms may be particularly affected by them. Under natural conditions soil invertebrates will likely be confronted with combinations of pollutants simultaneously, which may result in stronger negative effects if pollutants act synergistically. Within this work we study how multiple pollutants affect the soil-dwelling, substrate feeding earthworm Eisenia fetida. We compared the effects of the single stressors, polystyrene microplastic fragments, polystyrene fibers, brake dust and soot, with the combined effect of these pollutants when applied as a mixture. Endpoints measured were survival, growth, reproductive fitness, and changes in three oxidative stress markers. We found that among single pollutant treatments, brake dust imposed the strongest negative effects on earthworms in all measured endpoints including increased mortality rates. Sub-lethal effects were found for all pollutants. Exposing earthworms to all four pollutants simultaneously led to effects on mortality and oxidative stress markers that were smaller than expected by the respective null models. These antagonistic effects are likely a result of the adsorption of toxic substances found in brake dust to the other pollutants. With this study we show that effects of combinations of pollutants cannot necessarily be predicted from their individual effects and that combined effects will likely depend on identity and concentration of the pollutants.

“…Changes in feeding and growth of organisms have been one of the most commonly anticipated endpoints affected by exposure to microplastics, because of multiple recorded effects on the digestion through effects on the gut microbiota (Cheng et al, 2021;Ma et al, 2020), physical interactions with gut epithelium (Jiang et al, 2020), and clogging in the gut leading to changes in egestion rate (Lahive et al, 2022). However, growth and feeding rate of terrestrial invertebrates were not commonly changed after 21 days of exposure (Rodriguez-Seijo et al, 2017Selonen et al, 2021Selonen et al, , 2020.…”

“…Polypropylene MPs exposure can reduce diversity and alter microbial community in earthworms GM. Specifically, an increment in Aeromonadaceae and Pseudomonadaceae was observed with a decline of Nitrososphaeraceae and Proteobacteria ( 76 ). MPs can reach the intestine trait and accumulate interacting with GM and altering its composition.…”

Role-Playing Between Environmental Pollutants and Human Gut Microbiota: A Complex Bidirectional Interaction

There is a growing interest in the characterization of the involvement of toxicant and pollutant exposures in the development and the progression of several diseases such as obesity, diabetes, cancer, as well as in the disruption of the immune and reproductive homeostasis. The gut microbiota is considered a pivotal player against the toxic properties of chemicals with the establishment of a dynamic bidirectional relationship, underlining the toxicological significance of this mutual interplay. In fact, several environmental chemicals have been demonstrated to affect the composition, the biodiversity of the intestinal microbiota together with the underlining modulated metabolic pathways, which may play an important role in tailoring the microbiotype of an individual. In this review, we aimed to discuss the latest updates concerning the environmental chemicals–microbiota dual interaction, toward the identification of a distinctiveness of the gut microbial community, which, in turn, may allow to adopt personalized preventive strategies to improve risk assessment for more susceptible workers.
