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.
We all use plastics for a variety of purposes, and the amount of plastic produced and used is increasing worldwide, now reaching over 380 million metric tons (MMT) annually. Waste management in highly populated areas is currently insufficient to prevent large amounts...

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.
Microplastics in Urban Environments: Sources, Pathways, and Distribution
AI summary Read the abstract
Researchers mapped the major sources and pathways of microplastic pollution in cities, finding that tire wear, laundry wastewater, landfills, and construction activity collectively make urban areas major generators of the microplastics that flow into surrounding air, water, and soil.
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 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 Sinks of Microplastics
AI summary Read the abstract
Researchers catalogued the major sources and environmental sinks of microplastics globally, identifying the pathways by which these pervasive particles enter ecosystems and accumulate in ways that pose risks to human health and environmental integrity.
