ClearCharacterization of microplastics and their interaction with antibiotics in wastewater
Researchers characterized microplastics in wastewater and investigated their interactions with antibiotics, examining how microplastic surfaces adsorb antibiotic compounds and the implications for antibiotic transport and dissemination in wastewater treatment systems.
Pharmaceutically active micropollutants: origin, hazards and removal
This review summarizes existing research on pharmaceutical pollutants -- such as antibiotics, painkillers, and hormones -- found in water systems around the world. While focused on drug contamination, the paper notes that microplastics can act as carriers for these pharmaceutical chemicals, potentially concentrating them and increasing human exposure through drinking water. Conventional water treatment methods are often unable to fully remove these micropollutants.
Wastewater treatment plant effluent as a source of microplastics: review of the fate, chemical interactions and potential risks to aquatic organisms
This review examines wastewater treatment plant effluent as a source of microplastics entering aquatic environments. The study found that even though treatment plants remove most microplastics, the small amounts remaining in effluent may still contribute significantly to environmental contamination, and the chemical interactions between microplastics and other pollutants in wastewater raise additional ecological concerns.
Unveiling the Interactions Between the Antibiotic Resistome and Microplastics Influenced by Trace Elements and PPCPs in Wastewater Treatment Plants
Researchers monitored wastewater treatment plants containing microplastics, trace elements, and pharmaceutical/personal care products, finding that these co-occurring pollutants interact to influence the survival and spread of antibiotic-resistant bacteria and resistance genes through the treatment process.
Specific types of wastewater pollution in Ostrava and possibilities of decontamination through wastewater treatment plants
Researchers examined micropollutant contamination in wastewater in Ostrava, Czech Republic, finding that conventional wastewater treatment plants inadequately remove pharmaceutically active compounds and drug metabolites, posing risks to receiving waterways and highlighting the need for advanced treatment technologies.
Microplastics in wastewater treatment plants: Sources, properties, removal efficiency, removal mechanisms, and interactions with pollutants
This review examines microplastic sources, properties, removal efficiency, and removal mechanisms across different wastewater treatment plant stages. Researchers found that while treatment plants remove a significant portion of microplastics, they cannot eliminate them entirely, resulting in the continued release of millions of particles into the environment daily through effluent and sludge.
The Role of Wastewater Treatment Plants in Dissemination of Antibiotic Resistance: Source, Measurement, Removal and Risk Assessment
This review examines how wastewater treatment plants handle antibiotic-resistant bacteria and their resistance genes, finding that current treatment processes do not fully remove them. Different levels of treatment show varying removal rates, and resistant bacteria can still be found in treated water released into the environment. While not directly about microplastics, the findings are relevant because microplastics in wastewater can carry antibiotic-resistant bacteria into waterways.
Influence of wastewater treatment process on pollution characteristics and fate of microplastics
Researchers investigated microplastic abundance and removal efficiency across four wastewater treatment plants using different treatment technologies, finding influent concentrations between 539 and 1,290 particles per liter that were reduced substantially by primary and secondary treatment. Smaller microplastic particles proved hardest to remove and most likely to persist in final effluent.
Fate of microplastics in wastewater treatment plants and their environmental dispersion with effluent and sludge
Researchers tracked microplastics through a wastewater treatment plant and found 12 different polymer types in effluents and sludge, with smaller particles (25–104 μm) most abundant and fibres displaying lower sizes than fragments. The study demonstrates that WWTPs do not fully remove microplastics and that processed sludge marketed as soil amendment carries plastic contamination.
Research progress on the origin, fate, impacts and harm of microplastics and antibiotic resistance genes in wastewater treatment plants
This review explores how microplastics and antibiotic resistance genes interact in wastewater treatment plants, where they can survive treatment and enter the environment together. The concern for human health is that these contaminants can travel through the food chain, potentially increasing illness from antibiotic-resistant infections.
Chlorination of Antivirals in Wastewater: Effects of Microplastics and Ecotoxicity on Aquatic and Terrestrial Species
Researchers investigated how microplastics affect the chlorination of antiviral pharmaceuticals in secondarily treated wastewater and assessed ecotoxicity of the resulting products. Microplastics altered chlorination byproduct formation and in some cases increased overall ecotoxicity of treated wastewater, suggesting that microplastic co-occurrence complicates pharmaceutical disinfection outcomes.
Sustainable treatment systems for removal of pharmaceutical residues and other priority persistent substances
This review evaluates sustainable wastewater treatment technologies for removing pharmaceutical residues and other micropollutants before treated water is discharged to the environment. Advanced treatment methods are also applicable to improving microplastic removal from wastewater.
Study of occurrence, abundance, and characterization of microplastics in wastewater treatment plant in New Delhi, India
Researchers quantified microplastic prevalence in influent, treated effluent, and sludge from a wastewater treatment plant in New Delhi, finding that MPs are present throughout the treatment process and that the plant incompletely removes them, discharging MPs into receiving waters.
Recent advances on microplastics pollution and removal from wastewater systems: A critical review
This review summarizes the latest research on microplastic detection, occurrence, and removal in wastewater treatment plants. While treatment plants can remove 57-99% of microplastics depending on the stage, significant amounts still escape into the environment through treated water and sludge. The findings highlight the need for advanced treatment methods to prevent microplastics from reaching waterways and ultimately human water supplies.
Collaborative removal of microplastics, bacteria, antibiotic resistance genes, and heavy metals in a full-scale wastewater treatment plant
Researchers tracked how a full-scale wastewater treatment plant in China simultaneously removes microplastics, bacteria, antibiotic resistance genes, and heavy metals, finding that while the plant removed over 80% of incoming microplastics, those that remained in the effluent were associated with elevated levels of antibiotic resistance genes and heavy metals. Microplastics appeared to serve as carriers that concentrate and co-transport these co-contaminants through treatment processes. This raises important concerns: even "clean" treated wastewater discharged into rivers may carry microplastics loaded with antibiotic-resistant bacteria and toxic metals.
Meso- and microplastics accumulate and transfer hazardous contaminants from wastewater treatment plants to the environment
Researchers investigated how meso- and microplastics in wastewater treatment plants accumulate organic and inorganic pollutants, including metals, pharmaceuticals, and pesticides. They found that plastic particles act as carriers for these contaminants, redistributing them through both treated water discharge and sludge applied to land. The study suggests that wastewater treatment plants, while partially removing plastics, also serve as pathways for contaminated microplastics to reach the environment.
Transport and fate of microplastic particles in wastewater treatment plants
Researchers tracked microplastic particles through multiple stages of a wastewater treatment plant, finding that particles were concentrated in sludge but that a fraction passed through each treatment stage and remained in the final effluent.
Antibiotic resistance genes and virulence factors in the plastisphere in wastewater treatment plant effluent: Health risk quantification and driving mechanism interpretation
Researchers found that microplastics in treated wastewater carry significantly more disease-causing bacteria, antibiotic resistance genes, and virulence factors on their surfaces compared to the surrounding water. This means microplastics released from wastewater treatment plants into rivers and lakes could spread antibiotic-resistant infections, posing a direct risk to communities that rely on these water sources.
