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.

The escalating environmental concern over secondary microplastics (SMPs) stems from their physicochemical evolution primary (PMPs), yet the contribution of varying transformations to ultimate risks remains unknown. In this study, a photomechanical degradation process was employed convert sunscreen-derived (SDMPs) into SDMPs. While mechanical caused physical fragmentation, photodegradation induced both and chemical alterations, introducing surface oxidation, bond scission, cross-linking Employing combination alkaline digestion pyrolysis GC-MS techniques, it observed that fragmentation photooxidation led heightened intracellular sequestration MPs. Although bioaccumulated SDMPs could be indicated by enlarged lysosomes fragmented mitochondria, toxicity at cellular level primarily driven post-photodegradation. A nontargeted analysis employing high-resolution mass spectrometry identified 46 plastic-associated compounds in leachate, with photodegradation-induced playing crucial role dissociation hydrophobic additives oxidative conversion leached compounds. leachate exacerbated photodegradation, mitochondrial serving as subcellular biomarker, indicative toxicity. This study elucidates pivotal augmenting cytotoxicity SDMPs, shedding light on intricate interplay between risks.
