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

Environmental Technology & Innovation, Journal Year: 2024, Volume and Issue: 35, P. 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.

Bacterium-Phage Symbiosis Facilitates the Enrichment of Bacterial Pathogens and Antibiotic-Resistant Bacteria in the Plastisphere

Environmental Science & Technology, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 21, 2025

The plastisphere, defined as the ecological niche for microbial colonization of plastic debris, has been recognized a hotspot pathogenic and antibiotic-resistant bacteria. However, interactions between bacteria phages facilitated by well their impact on risks to public health, remain unclear. Here, we analyzed metagenomic data from 180 plastisphere environmental samples, stemming four different habitats two types (biodegradable nonbiodegradable plastics) obtained 611 nonredundant metagenome-assembled genomes (MAGs) 4061 phage contigs. community exhibited decreased diversity virulent proportion compared those found in environments. Indexes phage-host interaction networks indicated significant associations with (ARB), particularly biodegradable plastics. Known phage-encoded auxiliary metabolic genes (AMGs) were involved nutrient metabolism, antibiotic production, quorum sensing, biofilm formation which contributed enhanced competition survival pathogens ARB hosts. Phages also carried transcriptionally active virulence factor (VFGs) resistance (ARGs), could mediate horizontal transfer communities. Overall, these discoveries suggest that form symbiotic relationships hosts, encoding AMGs mediating gene (HGT) increase source plastisphere.

Biofilm-Colonized versus Virgin Black Microplastics to Accelerate the Photodegradation of Tetracycline in Aquatic Environments: Analysis of Underneath Mechanisms

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(14), P. 5714 - 5725

Published: March 30, 2023

Tire wear particles (TWPs) exposed to the aquatic environment are rapidly colonized by microorganisms and provide unique substrates for biofilm formation, which potentially serve as vectors tetracycline (TC) influence their behaviors potential risks. To date, photodegradation capacity of TWPs on contaminants due formation has not been quantified. accomplish this, we examined ability virgin (V-TWPs) biofilm-developed (Bio-TWPs) photodegrade TC when simulated sunlight irradiation. V-TWPs Bio-TWPs accelerated TC, with rates (kobs) 0.0232 ± 0.0014 0.0152 0.0010 h–1, respectively (kobs increased 2.5–3.7 times compared that only solution). An important factor behavior was identified linked changed reactive oxygen species (ROS) different TWPs. The were light 48 h, resulting in more ROS attacking hydroxyl radicals (•OH) superoxide anions (O2•–) playing a dominant role measured using scavenger/probe chemicals. This primarily greater photosensitization effects higher electron-transfer comparison Bio-TWPs. In addition, this study first sheds effect intrinsic mechanism crucial photodegradation, enhancing our holistic understanding environmental associated contaminants.
