A critical review of the adsorption-desorption characteristics of antibiotics on microplastics and their combined toxic effects

Environmental Technology & Innovation, Год журнала: 2024, Номер 35, С. 103729 - 103729

The interaction between microplastics (MPs) and pollutants is crucial for assessing the environmental risk of MPs. It necessary to pay attention adsorption/desorption behavior antibiotics on MPs due their potential role in antibiotic resistance. When MPs-loaded are ingested by organisms, they enter gastrointestinal tract undergo desorption, leading corresponding toxic effects. Existing literature primarily focuses adsorption behavior, while there a lack systematic generalizations desorption or combined effects organisms. Therefore, this article provides review mechanisms, biological tract. Desorption suggests that characteristics (aging hydrophobicity) components fluid (digestive enzyme species pH) can also have effect desorption. Moreover, summarizes induced MPs-antibiotics, demonstrating either enhance reduce plants, microorganisms, aquatic animals. Since methodological uniformity relevance natural environment main shortcomings existing literature, future research should focus actual water given region studying at gene, protein, metabolic levels. This direction expected provide valuable references insights evaluating antibiotics.

Ecological and Health Risk Mediated by Micro(nano)plastics Aging Process: Perspectives and Challenges

Environmental Science & Technology, Год журнала: 2025, Номер unknown

Опубликована: Март 19, 2025

Aged micro(nano)plastics (MNPs) are normally the ultimate state of plastics in environment after aging. The changes physical and chemical characteristics aged MNPs significantly influence their environmental behavior by releasing additives, forming byproducts, adsorbing contaminants. However, a systematic review is lacking on effects ecological human health regarding increasing but scattered studies results. This Review first summarizes unique methods for quantifying aging degree. Then we focused potential impacts organisms, ecosystems, health, including "Trojan horse" under real conditions. Through combining meta-analysis analytic hierarchy process (AHP) model, demonstrated that, compared to virgin MNPs, would result biomass decrease oxidative stress increase organisms lead total N/P greenhouse gas emissions ecosystems while causing cell apoptosis, antioxidant system reaction, inflammation health. Within framework risk assessment, used quotient (RQ) physiologically based pharmacokinetic (PBK) models as examples illustrate importance considering degree data acquisition, model building, formula evaluation. Given risks our urgent call more understand hazards real-world environments.

The effects of microplastics on ionoregulatory processes in the gills of freshwater fish and invertebrates: A prospective review

Comparative Biochemistry and Physiology Part A Molecular & Integrative Physiology, Год журнала: 2024, Номер 295, С. 111669 - 111669

Опубликована: Май 26, 2024

From review of the very few topical studies to date, we conclude that while effects are variable, microplastics can induce direct ionoregulatory disturbances in freshwater fish and invertebrates. However, intensity depends on microplastic type, size, concentration, exposure regime. More numerous where indirect inferences about possible be drawn; these indicate increased mucus production, altered breathing, histopathological gill structure, oxidative stress, alterations molecular pathways. All could have negative homeostasis. previous research has suffered from a lack standardized reporting characteristics conditions. Often overlooked is fact dynamic contaminants, changing over time through degradation fragmentation subsequently exhibiting surface chemistry, notably an presence diversity functional groups. The same groups characterized also present dissolved organic matter, often termed carbon (DOC), class substances for which far greater understanding their actions. We highlight instances resemble those DOC exposure. propose future investigations, vivo techniques proven useful should used including measurements transepithelial potential, net unidirectional radio-isotopic ion flux rates, concentration kinetic analyses uptake transport. sophisticated vitro approaches using cultured epithelia, Ussing chamber experiments surrogate membranes, scanning selective electrode (SIET) may prove useful. Finally, advocate minimum requirements properties experimental conditions help advance this important emerging field.

Microplastics in Inland Saline Lakes of the Central Ebro Basin, NE Spain

Water, Год журнала: 2025, Номер 17(7), С. 989 - 989

Опубликована: Март 28, 2025

Saline lakes are rare and fragile habitats with a high conservation scientific interest. We have studied the presence of microplastics (MPs) in water four inland saline located Central Ebro Basin (CEB), NE Spain. Quantification characterization MPs were performed by optical microscopy micro-Fourier Transform Infrared Spectroscopy (micro-FTIR). analyzed covered 5–5000 μm range. Most collected contained 250–500 500–1000 ranges. The concentration varied from 850 ± 271 to 1556 59 MPs/L, fibers being most dominant typology. Seven different colors observed, abundant black, seven types plastic identified, polyester, polyethylene terephthalate, nylon abundant. smallest presented more homogeneous MP size distribution wider variety color polymer composition. This work shows that these is at least one order magnitude higher than previous values reported similar environments, it expected multiply fast. highlights importance hydrological characteristics lakes, evapotranspiration only outflow, atmospheric deposition MPs, other anthropogenic causes.

This study investigated the effects of different aging treatments (UV light, potassium permanganate, and sodium hydroxide treatments) on adsorption lead (Pb(II)) by PET microplastics, as well impact Microcystis aeruginosa microplastics. The results indicated that significantly affected capacity which could be attributed to increased functional groups surface porosity during process. Kinetic analysis revealed Pb(II) follows a pseudo-second-order model, suggested process is mainly controlled chemical adsorption. Intraparticle diffusion further elucidated migration mechanism within On other hand, presence enhanced As concentration microalgae increases, promoting effect microplastics gradually strengthens, with extracellular polymeric substances (EPS) secreted playing key role in facilitating These findings strengthen carriers heavy metal aggravate risk pollution aquatic ecological environment.

The accumulation of plastic waste in the environment has raised widespread concern about impact microplastics (MPs) on human and environmental health, particularly regarding aged MPs. This study investigated effects subchronic dietary intake pristine polyethylene (PE-MPs) C57BL/6J mice. Results revealed that both PE-MPs, at doses 0.01 1 mg/day, induced plasma metabolic changes primarily associated with lipid metabolism digestive processes. These alterations were reflected expression proteins involved unsaturated fatty acid pathways liver as well a reduction beneficial gut microbiota. Key contributors toxicity PE-MPs included ATP-binding cassette transporters, bacteria (notably Lactobacillus, Akkermansia, Parasutterella, Turicibacter), significantly altered related to elongation, such acyl-CoA thioesterase enzyme family elongation very long chain protein 5. disruptions exacerbated disorders, potentially contributing diseases. Additionally, decreased levels glutathione S-transferase A proteins, along reduced hepatic increased reactive oxygen species small intestine liver, suggested aggravated intestinal damage through oxidative stress. findings indicated caused more severe dysfunction microbiota disruption. effect was likely mediated by transfer acids signaling molecules gut-liver axis, ultimately leading disorders
