“…The EPS had lowered bioavailability and toxicity by decreasing interactions between the Se NPs and fish embryos. [171] On the contrary, an environmental corona may also elevate the bioavailability of ENMs in fish. [172] For instance, surfactants (i.e., polysorbate 20, polysorbate 80, and SDS) exhibited synergistic toxicity with Au NPs in embryonic D. rerio, probably due to the increased bioavailability of surfactants by transport and internalization of the Au NPs.…”

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.

“…There is no permissible limit for selenium prescribed by national and international agencies. But several pieces of research have reported selenium toxicity in the aquatic environment [25][26][27][28]. Selenium is released from weathering of selenium-rich rocks and soil that enter into surface water through surface runoff.…”

The term heavy metals refer to any metallic element that possesses a specific density, mainly >5 g/cm 3 [1]. Heavy metals may enter into the aquatic ecosystem by natural as well asanthropogenic activities. The widespread contamination of aquatic bodies by these metals has engrossed worldwide attention due to their persistence and bio-accumulative nature [2-3]. Heavy metal pollution can be traced back to the Roman Empire [4]. A perusal of literature reveals that heavy metal contamination has been widely reported in water samples [5], soil [6], sediments and fishes [7] and lakes [8]. Anthropogenic activities like smelting,

“…Recently, the exploitation of microorganisms able to bioconvert Se-oxyanions to Se 0 has emer ged as a cost-effective green alternative strategy for the decontamination of Se-polluted environments, with a particular focus on surface waters and wastewaters. To date, Se-bioremediation approaches exploit bacterial strains capable of reducing SeO 4 2− and SeO 3 2− [23] either to conserve energy [61][62][63] or to detoxify their environmental niches [23]. Since Se-oxyanions bio-reduction under anoxic conditions is more characterized as compared to the aerobic mode, mainly anaerobic bacterial strains have been used for Se-decontamination purposes [23].…”

The chalcogens selenium (Se) and tellurium (Te) are rare earth elements, which are mainly present in the environment as toxic oxyanions, due to the anthropogenic activities. Thus, the increased presence of these chalcogen-species in the environment and the contamination of wastewaters nearby processing facilities led to the necessity in developing remediation strategies aimed to detoxify waters, soils and sediments. Among the different decontamination approaches, those based on the ability of microorganisms to bioaccumulate, biomethylate or bioconvert Se-and/or Te-oxyanions are considered the leading strategy for achieving a safe and eco-friendly bioremediation of polluted sites. Recently, several technologies based on the use of bacterial pure cultures, bacterial biofilms or microbial consortia grown in reactors with different configurations have been explored for Se-and Te-decontamination purposes. Further, the majority of microorganisms able to process chalcogen-oxyanions have been described to generate valuable Se-and/or Te-nanomaterials as end-products of their bioconversion, whose potential applications in biomedicine, optoelectronics and environmental engineering are still under investigation. Here, the occurrence, the use and the toxicity of Se-and Te-compounds will be briefly overviewed, while the microbial mechanisms of chalcogen-oxyanions bioprocessing, as well as the microbialbased strategies used for bioremediation approaches will be extensively described.

A comparison of fate and toxicity of selenite, biogenically, and chemically synthesized selenium nanoparticles to zebrafish (Danio rerio) embryogenesis

Abstract: Based on the data, it is contented that the presence of humic acid like substances of EPS on the surface of nano-Se b plays a major role in lowering the bioavailability (uptake) and toxicity of nano-Se b by decreasing the interactions between nanoparticles and embryos.ARTICLE HISTORY
