Environmental Science & Technology, Journal Year: 2021, Volume and Issue: 55(23), P. 15579 - 15595

As two major types of pollutants emerging concerns, microplastics (MPs) and antibiotics (ATs) coexist in aquatic environments, their interactions are a source increasing concern. Therefore, this work examines the interaction mechanisms MPs ATs, effect on ATs bioavailability antibiotic resistance genes (ARGs) abundance environments. First, for adsorption summarized, mainly including hydrophobic, hydrogen-bonding, electrostatic interactions. But other possible mechanisms, such as halogen bonding, CH/π interaction, cation−π negative charge-assisted hydrogen bonds, newly proposed to explain observed adsorption. Additionally, environmental factors (such pH, ionic strength, dissolved organic matters, minerals, aging conditions) affecting by specifically discussed. Moreover, could change bioaccumulation toxicity organisms, related joint reviewed analyzed. Furthermore, can enrich ARGs from surrounding environment, is evaluated. Finally, research challenges perspectives MPs–ATs implications presented. This review will facilitate better understanding fate risk both ATs.

Soil plastispheres as hotspots of antibiotic resistance genes and potential pathogens

The ISME Journal, Journal Year: 2021, Volume and Issue: 16(2), P. 521 - 532

Abstract In the Anthropocene, increasing pervasive plastic pollution is creating a new environmental compartment, plastisphere. How plastisphere affects microbial communities and antibiotic resistance genes (ARGs) an issue of global concern. Although this has been studied in aquatic ecosystems, our understanding microbiota soil ecosystems remains poor. Here, we investigated ARGs four types microplastics (MPs) from diverse environments, revealed effects manure, temperature, moisture on them. Our results showed that MPs select for plastisphere, these are involved metabolic pathways, indicating they could drive ecological processes ecosystem. The relationship within bacterial zero-radius operational taxonomic units (zOTUs) was predominantly positive, neutral appeared to dominate community assembly. However, deterministic were more important explaining variance plastispheres. A range potential pathogens detected which enriched compared but varied across types. We further found addition manure elevation temperature all enhance plastispheres, increase with moisture. These suggested plastispheres habitats increased pathogen abundance spatially co-located under change. findings provided insights into ecology microbiome resistome

Biofilms Enhance the Adsorption of Toxic Contaminants on Plastic Microfibers under Environmentally Relevant Conditions

Environmental Science & Technology, Journal Year: 2021, Volume and Issue: 55(13), P. 8877 - 8887

Published: June 21, 2021

Microplastics (MPs) exposed to the natural environment provide an ideal surface for biofilm formation, which potentially acts as a reactive phase facilitating sorption of hazardous contaminants. Until now, changes in contaminant capacity MPs due formation have not been quantified. This is first study that compared naturally aged, biofilm-covered microplastic fibers (BMFs) adsorb perfluorooctane sulfonate (PFOS) and lead (Pb) at environmentally relevant concentrations. Changes properties morphology aged (MF) were studied by area analysis, infrared spectroscopy, scanning electron microscopy. Results revealed MFs exhibited higher areas because biomass accumulation virgin samples followed order polypropylene>polyethylene>nylon>polyester. The concentrations adsorbed Pb PFOS 4–25% 20–85% varied among polymer types. increased adsorption was linked with altered hydrophobic/hydrophilic characteristics samples. Overall, present demonstrates biofilms play decisive role contaminant-plastic interactions significantly enhance vector potential toxic environmental We anticipate knowledge generated from this will help refine planetary risk assessment MPs.

Public summary•The plastisphere selectively assembles a microbiome distinct from that of natural habitats.•New microbial coexistence patterns are yielded in the plastisphere.•Altered functions threaten ecosystem functioning.•Enrichment pathogens poses critical challenge to "One Health".AbstractPlastic offers new niche for microorganisms, plastisphere. The ever-increasing emission plastic waste makes it understand ecology and associated effects. Here, we present global fingerprint plastisphere, analyzing samples collected freshwater, seawater, terrestrial ecosystems. community has clearly higher heterogeneity more deterministically dominated assembly compared habitats. New patterns—loose fragile networks with mostly specialist linkages among microorganisms rarely found habitats—are seen Plastisphere microbiomes generally have great potential metabolize organic compounds, which could accelerate carbon turnover. Microorganisms involved nitrogen cycle also altered especially freshwater plastispheres, where high abundance denitrifiers may increase release nitrite (aquatic toxicant) nitrous oxide (greenhouse gas).
