Microplastics as Emerging Pollutants in Urban Waterways
AI summary Read the abstract
This review examined microplastics as emerging pollutants in urban waterways, focusing on their sources, transport, association with toxic co-contaminants, and the health and ecological risks posed by their persistence in freshwater systems. Urban waterways concentrate microplastics from multiple city sources, creating exposure risks for communities relying on surface water and the aquatic organisms they consume.
Microplastics (MPs) have been classified as any plastic particle with a diameter less than 5 mm. MPs have been identified as a prominent environmental concern due to the fact that they associate with a wide range of toxic contaminants, and also because of their...

Microplastics Occurrence in Urban Water: Current Insights
AI summary Read the abstract
Researchers analyzed microplastic concentrations across urban water systems, compiling data on occurrence patterns and sources in drinking water infrastructure. The review highlights urban water supplies as a significant and underappreciated route of daily human microplastic exposure.
Sources and Fate of Microplastics in Urban Systems
AI summary Read the abstract
Urban environments generate microplastics through road runoff, stormwater drainage, and inadequate waste management, releasing particles directly into local waterways at high concentrations. Cities are both major sources and exposure zones for microplastics, making urban infrastructure improvements a priority for reducing human contact with contaminated water and air.
Sources and Fate of Microplastics in Urban Systems
AI summary Read the abstract
Researchers examined how microplastics enter and move through urban environments, tracing sources from personal care products, synthetic clothing, and infrastructure degradation to eventual fate in waterways — as global plastic production exceeds 380 million metric tons annually, cities are both major generators and transport corridors for microplastic pollution.
Plastics and Microplastics: Emerging Pollutants in the Water Systems and Potential Remedies
AI summary Read the abstract
Researchers reviewed how mismanaged single-use plastics are contaminating both freshwater and ocean ecosystems at alarming rates, and evaluated potential remediation strategies including filtration, biodegradation, and policy interventions. The review underscores that plastic pollution is now a systemic threat to water quality that affects drinking water sources globally.
Microplastics in Freshwater Ecosystems
AI summary Read the abstract
Researchers reviewed the evidence for microplastic contamination across freshwater environments, finding these particles in virtually all rivers and lakes studied — including remote wilderness areas. Microfibers from synthetic textiles are consistently the most common type found, suggesting laundry runoff is a major and underappreciated source.
