Nanomaterials in Water Purification: From Pathogens to Microplastics and Heavy Metals
AI summary Read the abstract
Researchers reviewed how nanotechnology-based materials can simultaneously remove pathogens, heavy metals, and microplastics from drinking water, offering multi-contaminant purification solutions. This work is directly relevant to human health because microplastic removal at the point of water treatment represents one of the most practical interventions for reducing daily human ingestion of plastic particles.
Recently, nanotechnology has been applied in various fields, including physics, chemistry, materials science, biology, and medicine. Nanotechnology is also applied in the removal of multiple impurities/pollutants, including pathogenic bacteria and viruses, from water...

Improvement of Wastewater Treatment Process Using Nanomaterials and Nanotechnology
AI summary Read the abstract
This review evaluated how nanomaterials—including nano-adsorbents, photocatalysts, and membranes—can improve wastewater treatment efficiency for emerging contaminants including microplastics, heavy metals, and pharmaceuticals. Advanced wastewater treatment is a critical line of defense against microplastic environmental release, as conventional treatment plants allow significant quantities of micro- and nanoplastics to pass through into receiving water bodies.
Microplastics in aquatic environment: fate, human exposure, removal and advances of nanotechnology in remediation
AI summary Read the abstract
This review traces microplastic pathways from aquatic sources — including seafood, drinking water, and sea salt — through the human food chain, estimating up to 26,250 microplastic particles ingested per person annually from seafood alone, while also cataloging the toxic additives and co-transported heavy metals these particles carry. It evaluates physical, chemical, and biological removal methods before identifying nanotechnology-based approaches as the most promising next generation of water treatment for microplastic elimination.
Nanoplastics in Wastewater: Monitoring, Ecotoxicity, and Remediation
AI summary Read the abstract
Researchers explore the challenges posed by nanoplastics in wastewater, examining monitoring methods for detecting these extremely small particles, their ecotoxicity to aquatic organisms and ecosystems, and promising remediation strategies for reducing nanoplastic contamination before treated water is discharged into the environment.
A mini-review on microplastics in drinking water treatment processes
AI summary Read the abstract
A review of drinking water treatment plants worldwide found that while processes like coagulation, filtration, and disinfection remove significant portions of microplastics, removal efficiency varies widely and no current standard treatment achieves complete elimination. This gap between laboratory findings and real-world treatment conditions means measurable microplastic concentrations persist in treated tap water consumed by billions of people daily.
