“…The above findings are consistent with the existing literature showing that significant excessive ROS were observed in C. reinhardtii , E. gracilis and C. vulgaris exposed to PS-NPLs with high concentrations ranging from 25 mg L −1 to ∼500 mg L −1 . 32,33,70 Interestingly, these previous observations showed adverse effects on microalgae when the NPL concentration was above 5 mg L −1 , 27,69 but in our study in a realistic freshwater environment (Lake Geneva water), smaller-sized PS-NPLs (20 nm) induced a significant ROS production at fairly low concentration (0.1 mg L −1 ). Moreover, 20 nm PS-NPLs induced more prominent enhancement of ROS production than larger-sized PS-NPLs (100 nm), and PS-NPLs exhibited 1.9–6.0 times higher ROS-inducing effect in Lake Geneva water than that in culture medium.…”

“…24,25 Unfortunately, only 1.34% of the 2540 exposure studies published until 2020 concerned the adverse effects of nano-and microplastics on microorganisms. 23,26,27 Some scattered evidence suggests that microbial taxa with different nutritional modes in freshwater microbial communities can actively interact with NPLs. For example, PS-NPLs reduce the cell viability, biomass and chlorophyll a concentration of freshwater microalgae Scenedesmus obliquus, 28 Microcystis aeruginosa, 29,30 Chlorella vulgaris, 31,32 and Chlamydomonas reinhardtii 33 and altered the metabolic diversity and functional structure of freshwater biofilms.…”

“…Global plastic pollution and the detection of micro- and nanoplastic particles in almost all environmental compartments and geographic regions has fuelled research into the possible effects of these particles on environmental organisms. One specific research question is whether nanoplastic particles exert specific and/or enhanced effects in organisms in comparison to microplastics [ 1 , 2 , 3 , 4 ]. However, studies have reported different conclusions regarding this question.…”

“…As reviewed by ref. [ 1 ], there are also indications of size-specific effects depending on the type of organism. However, it remains to be elucidated which size classes need specific attention for hazard evaluation, and whether additional particle characteristics play a role in hazardous effects.…”

Defining Quality Criteria for Nanoplastic Hazard Evaluation: The Case of Polystyrene Nanoplastics and Aquatic Invertebrate Daphnia spp.

Polystyrene nanoparticles are the most investigated type of nanoplastics in environmental hazard studies. It remains unclear whether nanoplastic particles pose a hazard towards aquatic organisms. Thus, it was our aim to investigate whether the existing studies and data provided therein are reliable in terms of data completeness. We used the example of Daphnia spp. studies for the purpose of polystyrene nanoplastic (nanoPS) hazard evaluation. First, a set of quality criteria recently proposed for nanoplastic ecotoxicity studies was applied. These rather general criteria for all types of nanoplastics and different test organisms were then, in the second step, tailored and refined specifically for Daphnia spp. and nanoPS. Finally, a scoring system was established by setting mandatory (high importance) as well as desirable (medium importance) criteria and defining a threshold to pass the evaluation. Among the existing studies on nanoPS ecotoxicity for Daphnia spp. (n = 38), only 18% passed the evaluation for usability in hazard evaluation. The few studies that passed the evaluation did not allow for conclusions on the hazard potential of nanoPS because there was no consensus among the studies. The greatest challenge we identified is in data reporting, as only a few studies presented complete data for hazard evaluation.

Environmental plastic wastes are potential health hazards due to their prevalence as well as their versatility in initiating physical, chemical, and biological interactions and transformations. Indeed, recent research has implicated the adverse effects of micro‐ and nano‐plastics, including their neurotoxicity, yet how plastic particulates may impact the aggregation pathway and toxicity of amyloid proteins pertinent to the pathologies of neurological diseases remains unknown. Here, electrospray ionization time‐of‐flight mass spectrometry (ESI‐TOF‐MS) is employed to reveal the polymorphic oligomerization of NACore, a surrogate of alpha‐synuclein that is associated with the pathogenesis of Parkinson's disease. These data indicate that the production rate and population of the NACore oligomers are modulated by their exposure to a polystyrene nanoplastic, and these cellular assays further reveal an elevated NACore toxicity in microglial cells elicited by the nanoplastic. These simulations confirm that the nanoplastic‐NACore association is promoted by their hydrophobic interactions. These findings are corroborated by an impairment in zebrafish hatching, survival, and development in vivo upon their embryonic exposure to the nanoplastic. Together, this study has uncovered the dynamics and mechanism of amyloidogenesis elevated by a nanoplastic trigger, shedding a new light on the neurological burden of plastic pollution.
