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.

Phenotypic and Gene Expression Alterations in Aquatic Organisms Exposed to Microplastics

International Journal of Molecular Sciences, Год журнала: 2025, Номер 26(3), С. 1080 - 1080

The use of plastics, valued for its affordability, durability, and convenience, has grown significantly with the advancement industry. Paradoxically, these very properties plastics have also led to significant environmental challenges. Plastics are highly resistant decomposition, resulting in their accumulation on land, where they eventually enter aquatic environments, due natural processes or human activities. Among microplastics, which tiny plastic particles, particularly concerning when ecosystems, including rivers seas. Their small size makes them easily ingestible by organisms, either mistake through feeding behaviors, poses serious risks. Moreover, microplastics readily adsorb other pollutants present creating pollutant complexes that can a synergistic impact, magnifying harmful effects compared acting alone. As result, extensive research focused understanding organisms. Numerous studies demonstrated organisms exposed alone combination pollutants, exhibit abnormal hatching, development, growth. Additionally, many genes, those associated antioxidant system, display expression patterns conditions. In this review, we examine impacts, discussing specific explore changes phenotype gene both independently adsorbed pollutants.

The adsorption of Fe(III) onto the surface microplastics (MPs) enhances their toxicity and mobility in aquatic environments, posing a serious threat to human health ecosystem balance. This study investigated mechanism influencing factors on three types MPs with varying particle sizes aging degrees using batch experiments freshwater saltwater. Machine learning (ML) techniques were employed predict capacity conduct attribution analysis. results showed that both saltwater followed Pseudo-First-Order kinetics Langmuir isotherms, indicating monolayer homogeneous physical reaction driven by oxygen-containing functional groups, hydrogen bonds aromatic rings MP surface. for was higher than saltwater, positively correlated degree pH value, but negatively size. Among tested ML models, Random Forest Gaussian Process Regression models Bayesian Optimization performed well predicting capacity, value identified as key based SHAP conducted comprehensive investigation behavior between water, providing valuable insights risk assessment prevention pollution environments.
