Transport of Traffic-Related Microplastic Particles in Receiving Water
AI summary Read the abstract
Traffic-generated microplastic particles, primarily from tire wear and road markings, are transported via stormwater runoff into urban waterways and ultimately marine environments, making roads a significant but underappreciated land-based source of ocean microplastic pollution. Quantifying this transport pathway is essential for developing effective urban stormwater management strategies to reduce microplastic loads in receiving waters.
A majority of microplastic particles (MPs) in marine waters are transported with rivers from land-based sources. Traffic is estimated to be one of the largest sources of MPs, hence stormwater and subsequently urban waterways are expected to be important...

Transport Mechanism of Microplastic in the Environment
AI summary Read the abstract
This review described the physical and chemical mechanisms by which microplastics are transported through air, water, and soil — including atmospheric deposition, hydrological flow, bioturbation, and biofouling — that collectively explain their detection in remote environments from Arctic sea ice to mountain summits. Elucidating these transport mechanisms reveals that no geographic location or ecosystem is isolated from microplastic contamination, underscoring the inevitability of human exposure through air, water, and food globally.
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.
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.
Microplastic Sources, Transport, Exposure, Analysis and Removal
AI summary Read the abstract
Researchers review microplastic sources, transport pathways, and degradation dynamics in both marine and freshwater ecosystems — including lakes, rivers, and estuaries — and assess current methods for exposure analysis and microplastic removal from aquatic environments.
