Summary: Dietary pollution by polystyrene microplastics (MPs) can cause hepatic injuries and microbial dysbiosis. EGCG, the major polyphenol in green tea, has a protective effect on liver by modulating the gut microbiota. However, the mechanisms underlying MPs-induced hepatic injuries and the protective effect of EGCG are still not fully understood.

Summary: This study constructed a carp polystyrene microplastics (PS-MPs) exposure model to investigate the damage and mechanism of PS-MPs exposure to carp myocardial tissue. The results showed that PS-MPs exposure induced inflammation, apoptosis, and necrosis in carp myocardial tissue and cardiomyocytes. Furthermore, PS-MPs exposure significantly increased the expression of TLR4 pathway-related factors and the NF-kappa B pathway and inflammation-related factors in a dose-dependent manner. These findings provide essential insights into the toxicological studies on PS-MPs and have important implications for aquaculture.

Summary: The aim of this study was to investigate the effects of intestinal exposure to polyethylene (PE) microplastics on gut homeostasis. Mice were orally exposed to PE microbeads of two different sizes, and it was found that ingestion of PE microbeads led to intestinal disturbances and significant alterations of crucial intestinal markers. This highlights the need for further research on the health impact of microplastic exposure in humans.

Summary: Emerging studies have shown that exposure to environmental micro- and nanoplastics can lead to toxicity in organisms, including oxidative stress, energy metabolism disorders, and gene damage. Furthermore, micro- and nanoplastics have been found in human fecal samples, placentas, lung tissue, and blood, posing a growing threat to global public health. However, current research on the health effects of micro- and nanoplastics in humans is limited, and more robust data and experiments are needed to understand the specific mechanisms. This review provides insights into micro- and nanoplastic toxicity and opens up avenues for further research.

Summary: Plastic-eating insects like the greater wax moth show promise in reducing plastic pollution through biodegradation, with the potential for enhanced metabolism with the involvement of gut microbiota. This study found that polystyrene microplastics can be depolymerized and digested in greater wax moths independently of gut microbiota, indicating efficient biodegradation by the insects' enzymes. Proposed potential metabolic pathways for polystyrene degradation in the insects' intestines provide insight for further research on enzyme identification and catalytic mechanisms.

Summary: Polystyrene microplastics (PS-MPs) have become a concerning pollutant due to their widespread production and usage. This study found that PS-MPs exposure activated hippocampal inflammation and induced anxiety-like behavior in mice. PS-MPs also disrupted gut microbiota, impaired the intestinal barrier, and caused peripheral inflammation. Eliminating the gut microbiota protected against the deleterious effects of PS-MPs and green tea's bioactive constituent EGCG showed preventive potential.

Summary: In this study, the researchers investigated the impact of particulate microplastics generated from polyethylene terephthalate (PM-PET) on the gut using mouse models and various analytical methods. The results showed that chronic and physiological low dose exposure to PM-PET did not affect intestinal pathology and mucin barriers, but had a substantial impact on the transcriptome and metabolisms of gut immune cells. The composition of the gut microbiota was also modestly affected by PM-PET exposure.

Summary: This study explores the impact of polystyrene microplastics (PS MPs) on liver repair during acute liver injury. The results show that pre-treatment with PS MPs exacerbates mortality and hepatocyte apoptosis in mice, suppresses hepatic cell proliferation, and disrupts the inflammatory response. Additionally, PS MPs delay the polarization capacity of macrophages to anti-inflammatory sub-type, leading to tissue repair suppression.

Summary: The adverse effects of microplastics on gut microbiota in aquatic animals are dependent on the chemicals and biofilm present in the microplastics. Therefore, understanding the influences of these characteristics is crucial to grasp the consequences of microplastics ingestion by aquatic organisms. Research on the impacts of microplastics on gut microbial communities within aquatic animals, involving chemical components and biofilm, is necessary for future studies on this subject.

Summary: By feeding carp with polystyrene microplastics (PS-MPs) particles of 8 μm in size and a concentration of 1000 ng/L water, a PS-MPs model of carp was established. An abnormal increase in the activities of AKP, ALT, AST, and LDH in the hepatopancreas indicated damage to this organ's function caused by PS-MPs. PS-MPs also induced oxidative stress, with a decrease in the activities of antioxidant enzymes and excessive accumulation of reactive oxygen species. Furthermore, PS-MPs activated the Toll-like receptor-2 (TLR2) signaling pathway, leading to increased expression of inflammatory molecules in both hepatopancreas and hepatocytes.

Summary: Microplastics are common pollutants that have various plastic applications. They can now be found in the air and inhaled into the lungs, leading to respiratory diseases. This study utilized mice models to demonstrate that exposure to polystyrene microplastics (PS-MPS) of different sizes caused severe inflammatory responses, apoptosis, and collagen deposition in the lungs, with smaller sizes having more noticeable damage. The study also found that PS-MPS targeted binding to Toll-like receptor 2 (TLR2), exacerbating fibrosis by promoting inflammation, oxidative stress, and apoptosis through activation of the NF-KB signal pathway.

Summary: A lack of zinc in freshwater environments causes slow growth, malnutrition, and abnormal biological functions in organisms. In this study, a zinc deficiency model of grass carp hepatocytes was established using TPEN. The results showed increased LDH, AST, ALT, and AKP activities, as well as ROS levels and decreased antioxidant enzyme activities in a zinc-deficient environment. RT-PCR and ELISA demonstrated increased expression levels of genes related to endoplasmic reticulum stress, apoptosis, and inflammation. These findings suggest that zinc deficiency induces inflammation and apoptosis in grass carp hepatocytes in the presence of calcium, highlighting the adverse effects of zinc deficiency in freshwater environments.

It was observed that exposure to microplastics caused damage to the intestinal mucosal surface and an increase in goblet cells. The study also found that microplastic exposure led to lymphocyte proliferation and aggregation in the intestinal wall, resulting in cellular apoptosis. The activation of NF-KB pathway and ferroptosis induced by lipid peroxidation were identified as the potential mechanisms underlying microplastic-induced intestinal damage.

Transcriptome analysis revealed differential expression of genes involved in oxidation-reduction, inflammation, and apoptosis, particularly related to the NF-KB and MAPK pathways. Further investigation showed that Se deficiency led to excessive accumulation of ROS, decreased activity of antioxidant enzymes, and upregulation of the NF-KB and MAPK pathways.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.
