“…Previous studies have demonstrated that ENMs have adverse effects on the growth, morphology, and photosynthesis of algae. [135] In recent years, there has been increasing value placed on the importance of environmental corona for these hazards. For instance, with 5 mg L −1 dissolved HA or the surface saturation of HA, the halfmaximal inhibitory concentration (IC 50 ) of TiO 2 NPs on Chlorella sp.…”

In aquatic environments, a large number of ecological macromolecules (e.g., natural organic matter (NOM), extracellular polymeric substances (EPS), and proteins) can adsorb onto the surface of engineered nanomaterials (ENMs) to form a unique environmental corona. The presence of environmental corona as an eco–nano interface can significantly alter the bioavailability, biocompatibility, and toxicity of pristine ENMs to aquatic organisms. However, as an emerging field, research on the impact of the environmental corona on the fate and behavior of ENMs in aquatic environments is still in its infancy. To promote a deeper understanding of its importance in driving or moderating ENM toxicity, this study systemically recapitulates the literature of representative types of macromolecules that are adsorbed onto ENMs; these constitute the environmental corona, including NOM, EPS, proteins, and surfactants. Next, the ecotoxicological effects of environmental corona‐coated ENMs on representative aquatic organisms at different trophic levels are discussed in comparison to pristine ENMs, based on the reported studies. According to this analysis, molecular mechanisms triggered by pristine and environmental corona‐coated ENMs are compared, including membrane adhesion, membrane damage, cellular internalization, oxidative stress, immunotoxicity, genotoxicity, and reproductive toxicity. Finally, current knowledge gaps and challenges in this field are discussed from the ecotoxicology perspective.

“…The second barrier is the plasma membrane, common to all cells. Chemical composition and architecture of the cell wall vary according to the organism, being their thickness an important factor in the determination of the NPs internalisation (Chen et al 2019 ). This cell structure is generally seen as a porous matrix.…”

“…After crossing the cell wall (in organisms with a cell wall and when such passage is possible), MOx NPs meet the cell membrane and two types of events can occur: damage of the membrane (due to physical disruption) (Chen et al 2019 ) or passage through the membrane by endocytosis (Fig. 1D ), a process well known in mammalian cells (Oh and Park 2014 ).…”

“…Once inside the cells, MOx NPs can undergo several alterations, such as redox transformations and complexation (Chen et al 2019 ) or can be solubilized inside of acidic lysosomes (Fig. 1D ) and exerts their toxicity by a Trojan horse-type mechanism (Oh and Park 2014 ).…”

“…In the last five years, several review papers have been published about NMs, NPs or more specifically on MOx NPs. Some reviews refer more broadly to NMs, namely about their behaviour, fate, bioavailability and effects on the environment (Pulido-Reyes et al 2017 ; Lead et al 2018 ; Spurgeon et al 2020 ; Zhao et al 2020 ) or the toxicity mechanisms associated with NMs over algal cells (Chen et al 2019 ). Within NMs, reviews on NPs, namely about the influence of their physico-chemical properties on ecotoxicology, in terrestrial and aquatic systems (Bundschuh et al 2018 ; Nguyen et al 2020 ; Roma et al 2020 ), the effects on freshwater organisms (Deniel et al 2019 ), genotoxicity (Mortezaee et al 2019 ) or the mechanisms associated with cell dead by necrosis, apoptosis and autophagy (Mohammadinejad et al 2019 ; Paunovic et al 2020 ) have been published.…”

In this article, we performed a literature review on the metallic, metal oxide, and metalloid nanoparticles (NP) effects on freshwater microcrustaceans, specifically focusing on (i) the main factors influencing the NP toxicity and (ii) their main ecotoxicological effects. Also, given that most studies are currently developed on the standard test species Daphnia magna Straus, we analyzed (iii) the potential differences in the biological responses between D. magna and other freshwater microcrustacean, and (iv) the ecological implications of considering only D. magna as surrogate of other microcrustaceans. We found that NP effects on microcrustaceans depended on their intrinsic properties as well as the exposure conditions. Among the general responses to different NP, we identified body burial, feeding inhibition, biochemical effects, metabolic changes, and reproductive and behavioral alterations. The differences in the biological responses between D. magna and other freshwater microcrustacean rely on the morphology (size and shape), ecological traits (feeding mechanisms, life cycles), and intrinsic sensitivities. Thus, we strongly recommend the use of microcrustaceans species with different morphological, physiological, and ecological characteristics in future ecotoxicity tests with NP to provide relevant information with regulation purposes regarding the discharge of NP into aquatic environments. Practitioner points Nanoparticles effects depend on intrinsic and external factors. Nanoparticles affect the morphology, physiology, and behavior. Effects on Daphnia differ from other microcrustaceans. The use of more diverse test species is suggested.
