Researchers developed a multidisciplinary modeling framework to simulate antimicrobial resistance (AMR) spread in riverine ecosystems, incorporating wastewater discharge, agricultural runoff, and microplastic-associated resistance gene transfer. The model predicted AMR gene concentrations along river corridors and identified intervention points for reducing environmental AMR dissemination.
Meta-analysis unravels the complex combined toxicity of microplastics and antibiotics in aquatic ecosystems
A meta-analysis of 730 datasets found that microplastics amplify antibiotic accumulation in aquatic organisms and worsen effects on growth, development, and immune function, but paradoxically appear to mitigate reproductive toxicity from antibiotics. The impact depends on biological response pathway, microplastic concentration, antibiotic properties, and exposure time, with an inverse relationship between antibiotic toxicity and both microplastic concentration and exposure duration.
Antimicrobial Resistance in Exploited Estuaries: Some Overlooked Environmental Contaminants and Microbial Niches Might Act as Drivers
This review examined antimicrobial resistance in exploited estuaries, identifying overlooked environmental contaminants including antibiotics, heavy metals, and biocides as drivers of resistance gene spread in estuarine microbiomes with implications for human health and food safety.
Antibiotic and Non-Antibiotic Determinants of Antimicrobial Resistance: Insights from Water Ecosystems
This review explains how non-antibiotic pollutants like heavy metals, biocides, and microplastics are contributing to antibiotic resistance in water systems, beyond the well-known problem of antibiotic overuse. Wastewater treatment plants are hotspots where these pollutants interact with bacteria, promoting the spread of resistance genes through mobile genetic elements. The findings are concerning for human health because drug-resistant bacteria from water environments can ultimately reach people through drinking water and food.
Antibiotic resistance in aquaculture and aquatic organisms: a review of current nanotechnology applications for sustainable management
Researchers reviewed how antibiotics released from aquaculture and other industries accumulate in aquatic ecosystems, promoting antibiotic resistance, and assessed nanotechnology-based interventions — including nanodrug delivery, nanoformulations, and nanosensors — as promising tools for sustainable management of these emerging contaminants.
Contribution of microplastic particles to the spread of resistances and pathogenic bacteria in treated wastewaters
Researchers studied microplastic particles collected from treated wastewater effluents and found that MPs harbored significantly higher loads of antibiotic resistance genes and pathogenic bacteria compared to surrounding water, suggesting MPs facilitate their environmental spread.
The nexus of microplastics, food and antimicrobial resistance in the context of aquatic environment: Interdisciplinary linkages of pathways
This review examines how microplastics in aquatic environments serve as surfaces where bacteria can grow, share antibiotic resistance genes, and then enter the food chain through contaminated seafood. The combination of microplastic pollution and antimicrobial resistance creates a compounding threat, as resistant bacteria riding on plastic particles can survive water treatment and reach humans. The authors call for interdisciplinary research connecting environmental science and public health to address this growing risk.
An alternative approach to risk rank chemicals on the threat they pose to the aquatic environment

Combined pollution of tetracyclines and microplastics in the aquatic environment: Insights into the occurrence, interaction mechanisms and effects
This review examines how microplastics and tetracycline antibiotics interact in water environments, since microplastics can absorb and carry antibiotics on their surfaces. Factors like pH, heavy metals, and organic matter in water influence how tightly antibiotics bind to microplastics, and the combined pollution is more harmful to aquatic life than either pollutant alone. This is relevant to human health because these microplastic-antibiotic combinations can enter drinking water supplies and promote antibiotic resistance.
Antibiotic resistance genes in treated wastewater and in the receiving water bodies: A pan-European survey of urban settings
Researchers surveyed 16 wastewater treatment plants across ten European countries and found that antibiotic resistance genes — DNA instructions that help bacteria survive antibiotics — are consistently released into rivers receiving treated wastewater. The study found that plants with more biological treatment steps had lower levels of these genes, suggesting that upgrading treatment infrastructure could reduce the spread of antibiotic resistance in the environment.
