“…Different biological responses (stronger in seawater) and species-specific responses were found, which in some cases also depended on the soaking time. The need to use test batteries for ecotoxicological risk assessment (ERA) of plastic elutriates is thus confirmed, as also pointed out by other authors, including Gao et al (2022) [55]. The species most sensitive to this form of pollution were algae, followed by the bioluminescent bacterium A. fischeri, and then by the primary consumers D. magna and P. lividus.…”

“…Living organisms integrate the positive and negative effects of chemicals with which they come into contact with the environmental conditions to which they are exposed during the experiment and respond to the biologically active components present [52]. Considering the varying sensitivity of organisms to chemicals [53], as well as the overall toxicity of various chemicals released from plastics, the need for a battery of bioassays covering a wide range of trophic levels to assess the toxicity and ecological risks of plastic leachates is evident [54,55]. Organisms from different trophic levels play a fundamental role in maintaining balance in ecosystems, and their characteristics have become an important index for assessing environmental quality [56].…”

The most worrisome fraction within plastic pollution is that of microplastics (MP). A category of MP almost completely ignored is that of glitter. The objective of this study is to test the toxicity of nine types of glitter leachate (3 soak times: 3, 90 and 180 days) on model organisms in freshwater (Allivibrio fischeri, Raphidocelis subcapitata, Daphnia magna) and saltwater (Allivibrio fischeri, Phaeodactylum tricornutum, Paracentrotus lividus). An integrated approach was applied to obtain the percentage of ecotoxicological risk. The results show that (i) photosynthesizing primary producers are the most sensitive trophic level; (ii) algae transitioned from growth inhibition to biostimulation; (iii) D. magna showed higher sensitivity after 48 h compared to 24 h; (iv) A. fischeri responded more strongly in saltwater than in freshwater. The integrated data show a greater risk associated with the marine environment, with the highest risk for glitters that are hexagonal and composed of poly-methyl-methacrylate. Our multivariate analysis shows that the toxicity of plastic leaching is a complex phenomenon that depends on the sensitivity of the species, in some cases on the soaking time and on the medium, and is not clearly linked to the polymer type, the contact area or the colors of the particles.

“…Owing to the prevalence of takeout food trends, it can be predicted that humans are highly likely to ingest these additives and byproducts in their diet, and aquatic organisms will also passively be exposed to these compounds once they are discarded into the environment. Additionally, though conventional plastic (i.e., PP, PE) containers may be partially gradually substituted with biodegradable plastic (whose environmental safety is still under severe disputes), , the latter is using similar or even greater quantities of additives and thus the potential health issue still exists. Certain limitations exist in the current study.…”

Ordering takeout is a growing social phenomenon and may raise public health concerns. However, the associated health risk of compounds leaching from plastic packaging is unknown due to the lack of chemical and toxicity data. In this study, 20 chemical candidates were tentatively identified in the environmentally relevant leachate from plastic containers through the nontargeted chemical analysis. Three main components with high responses and/or predicted toxicity were further verified and quantified, namely, 3,5-di-tert-butyl-4-hydroxycinnamic acid (BHC), 2,4-di-tert-butylphenol (2,4-DTBP), and 9-octadecenamide (oleamide). The toxicity to zebrafish larvae of BHC, a degradation product of a widely used antioxidant Irganox 1010, was quite similar to that of the whole plastic leachate. In the same manner, RNA-seq-based ingenuity analysis showed that the affected canonical pathways of zebrafish larvae were quite comparable between BHC and the whole plastic leachate, i.e., highly relevant to neurological disease, metabolic disease, and even behavioral disorder. Longer-term exposure (35 days) did not cause any effect on adult zebrafish but led to decreased hatching rate and obvious neurotoxicity in zebrafish offspring. Collectively, this study strongly suggests that plastic containers can leach out a suite of compounds causing non-negligible impacts on the early stages of fish via direct or parental exposure.

“…In addition to enabling the measurement of clinically relevant parameters and showing the health status of individuals [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ], TENGs can complement traditional power sources, which are generally fabricated using toxic chemicals and have limited capacity. The introduction of TENGs into the operation and implementation of the above-mentioned systems could alleviate the dependence on power sources and sensor technology, thus increasing wireless mobility, interactivity, and intelligence [ 17 , 18 , 19 , 20 , 21 , 22 ]. TENGs can be especially helpful in the treatment of chronic stubborn disorders, in which rapid recovery often fails to be achieved.…”

Triboelectric nanogenerators (TENGs) were initially invented as an innovative energy−harvesting technology for scavenging mechanical energy from our bodies or the ambient environment. Through adaptive customization design, TENGs have also become a promising player in the self-powered wearable medical market for improving physical fitness and sustaining a healthy lifestyle. In addition to simultaneously harvesting our body’s mechanical energy and actively detecting our physiological parameters and metabolic status, TENGs can also provide personalized medical treatment solutions in a self-powered modality. This review aims to cover the recent advances in TENG-based electronics in clinical applications, beginning from the basic working principles of TENGs and their general operation modes, continuing to the harvesting of bioenergy from the human body, and arriving at their adaptive design toward applications in chronic disease diagnosis and long-term clinical treatment. Considering the highly personalized usage scenarios, special attention is paid to customized modules that are based on TENGs and support complex medical treatments, where sustainability, biodegradability, compliance, and bio-friendliness may be critical for the operation of clinical systems. While this review provides a comprehensive understanding of TENG-based clinical devices that aims to reach a high level of technological readiness, the challenges and shortcomings of TENG-based clinical devices are also highlighted, with the expectation of providing a useful reference for the further development of such customized healthcare systems and the transfer of their technical capabilities into real-life patient care.
