Microplastics: Emerging Issues in Emerging Urbanization
AI summary Read the abstract
Rapid urbanization is intensifying microplastic contamination in groundwater, soil, and oceans as waste management infrastructure fails to keep pace with plastic consumption. Growing urban populations face increasing microplastic exposure through drinking water and food, making this an urgent public health issue tied to urban planning and policy.
Microplastics had been previously excluded from the data on global plastic pollution. Reports of findings from recent years have placed microplastics higher up the priority list. Microplastics have made their way into groundwater, soil, and the oceans. They have also...

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.
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.
Emerging Trends in Microplastic Pollution Management
AI summary Read the abstract
Researchers highlight that microplastic pollution in aquatic and terrestrial ecosystems is increasing exponentially, contaminating human food items at growing rates, and examine emerging trends and management strategies needed to address this accelerating global challenge.
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.
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.
