“…Even though many authors have confirmed that the feeding type greatly affects ingestion of microplastics in aquatic biota (Scherer et al 2017), we believe that the high uptake rate of individuals does not necessarily cause significant or negative effects at the community level. This is particularly true for freshwater gastropods that have become tolerant to microplastics due to specific adaptations, despite high uptake rates (Weber et al 2021), or for freshwater Oligochaeta whose microplastic exposure did not result in any lethal or sublethal effects (Castro et al 2020; Silva et al 2020), as well as for amphipod and isopod crustaceans (Redondo‐Hasselerharm et al 2020).…”

Benthic communities contain some of the most threatened organisms in aquatic habitats due to different anthropogenic pressures. The high abundance of microplastics in sediments will continue to increase in the future, further increasing the probability of interactions between macroinvertebrates and microplastics. In the present study, a benthic community in a relatively pristine shallow pond was exposed either to an environmentally relevant high concentration of a microplastic mixture of 80 g m–2 in the sediment, or a control sediment, without the addition of microplastics. The mixture of microplastics contained irregularly shaped polyethylene, polyvinyl chloride, and polyamide in a ratio of 50:25:25%, respectively. The in situ experiment lasted for 100 d. The total number of taxa that colonized the microcosms was 22 (17 in the control and 18 in the microplastic treatment), and the colonization was not affected by the treatment. The most dominant group within the macroinvertebrate community was the dipteran family Chironomidae, in both the control and the microplastic treatment. No significant differences in the abundance and biomass at a community level were recorded between the groups by permutational multivariate analysis of variance (F = 0.993, p = 0.456 and F = 0.344, p = 0.797, respectively). The mixture of microplastics did not influence the abundance or biomass of the functional feeding groups (F = 1.810, p = 0.137 and F = 0.377, p = 0.736, respectively). The species richness, species abundance, species biomass, Shannon's diversity index, and Simpson's index of diversity showed no statistically significant differences between the control and treatment groups. Czekanowski's quantitative similarity index indicated that 84% of the community remained unaffected after microplastic exposure. Environ Toxicol Chem 2022;41:888–895. © 2021 SETAC

“…Long-term assays were performed according to Castro et al (2020) and Felipe et al (2020). A total of 312 healthy worms (4-6 mm long) presenting absent fission zones were separated from four cultivation vessels and placed in glass Petri dishes containing 50 mL of chlorine-free filtered tap water.…”

Antibiotics from sulfonamide, fluoroquinolone, and diaminopyrimidine classes are widely used in human and veterinary medicine, and their combined occurrence in the aquatic environment is increasing around the world. In parallel, the understanding of how mixtures of these compounds affect non‐target species from tropical freshwaters is scarce. Thus, this work aimed to study the long‐term reproductive, recovery, and swimming effects of mixtures of 12 antibiotics from three different classes (up to 10 μg L−1) added to freshwater (FWM) and synthetic wastewater (SWM) matrices on freshwater worm Allonais inaequalis. Results revealed that at the reproduction level, the exposure to antibiotics in the SWM matrix does not cause a significant toxic effect on species after 10 days. On the other hand, exposures to initial dose mixtures (10 μg L−1 each) in FWM caused a significant reduction of offspring by 19.2%. In addition, recovery bioassays (10 days in an antibiotic‐free environment) suggested that A. inaequalis has reduced offspring production due to previous exposure to antibiotic mixtures in both matrices. Furthermore, despite slight variation in swimming speed over treatments, no significant differences were pointed out. Regarding antibiotics in the water matrices after 10‐day exposures, the highest concentrations were up to 2.7, 7.8, and 4.2 μg L−1 for antibiotics from sulfonamide, fluoroquinolone, and diaminopyrimidine classes, respectively. These findings suggest that a species positioned between primary producers and secondary consumers may experience late reproductive damage even in an antibiotic‐free zone, after previous 10‐day exposure to antibiotic mixtures.Practitioner Points A mixture of sulfonamide, fluoroquinolone, and diaminopyrimidine antibiotics in freshwater affects the offspring production of A. inaequalis after 10 days. After the 10‐day antibiotic exposure, the reproduction of A. inaequalis remains affected in an antibiotic‐free environment over the recovery period. The swimming speed of the worms does not change after 10 days of exposure to the antibiotic mixture. The concentration of dissolved solids can limit the natural degradation of sulfonamide, fluoroquinolone, and diaminopyrimidine antibiotics in the aquatic environment.

“…The most common species used in toxicological studies are Pristina leidyi , Branchiura sowerbyi , Lumbriculus variegatus , Tubifex tubifex , and Allonais inaequalis (Lobo et al ., 2016; Hurley, Jamie & James, 2017; Neto et al ., 2019, Felipe et al ., 2020). L. variegatus , T. tubifex and A. inaequalis are the most widely used species for evaluating toxic effects caused by MPs and MWCNTs (Castro et al ., 2020; Scopetani et al ., 2020; Silva et al ., 2021). Transmission electron microscopy showed that MWCNTs do not penetrate cell membranes, and that toxicity caused by ingesting them might result from metals solubilised from the nanotubes (Mwangi et al ., 2012).…”

Aquatic invertebrates play a pivotal role in (eco)toxicological assessments because they offer ethical, cost‐effective and repeatable testing options. Additionally, their significance in the food chain and their ability to represent diverse aquatic ecosystems make them valuable subjects for (eco)toxicological studies. To ensure consistency and comparability across studies, international (eco)toxicology guidelines have been used to establish standardised methods and protocols for data collection, analysis and interpretation. However, the current standardised protocols primarily focus on a limited number of aquatic invertebrate species, mainly from Arthropoda, Mollusca and Annelida. These protocols are suitable for basic toxicity screening, effectively assessing the immediate and severe effects of toxic substances on organisms. For more comprehensive and ecologically relevant assessments, particularly those addressing long‐term effects and ecosystem‐wide impacts, we recommended the use of a broader diversity of species, since the present choice of taxa exacerbates the limited scope of basic ecotoxicological studies.This review provides a comprehensive overview of (eco)toxicological studies, focusing on major aquatic invertebrate taxa and how they are used to assess the impact of chemicals in diverse aquatic environments. The present work supports the use of a broad‐taxa approach in basic environmental assessments, as it better represents the natural populations inhabiting various ecosystems. Advances in omics and other biochemical and computational techniques make the broad‐taxa approach more feasible, enabling mechanistic studies on non‐model organisms. By combining these approaches with in vitro techniques together with the broad‐taxa approach, researchers can gain insights into less‐explored impacts of pollution, such as changes in population diversity, the development of tolerance and transgenerational inheritance of pollution responses, the impact on organism phenotypic plasticity, biological invasion outcomes, social behaviour changes, metabolome changes, regeneration phenomena, disease susceptibility and tissue pathologies. This review also emphasises the need for harmonised data‐reporting standards and minimum annotation checklists to ensure that research results are findable, accessible, interoperable and reusable (FAIR), maximising the use and reusability of data. The ultimate goal is to encourage integrated and holistic problem‐focused collaboration between diverse scientific disciplines, international standardisation organisations and decision‐making bodies, with a focus on transdisciplinary knowledge co‐production for the One‐Health approach.
