Occurrence, environmental behavior, and co-pollution of microplastics with HMs in urban channelized rivers
Summary
Researchers investigated the occurrence, environmental behavior, and co-pollution dynamics of microplastics and heavy metals in urban channelized rivers, examining how frequent anthropogenic activities introduce these contaminants into aquatic ecosystems. The study characterized spatial distribution patterns and interactions between microplastics and heavy metals, contributing to understanding combined pollution risks in urban waterways.
Complex and frequent anthropogenic activities have released tons of numerous exogenous pollutants into aquatic ecosystems, notably heavy metals (HMs) and microplastics (MPs) in urban channelized rivers.

Environmental behavior of microplastic - heavy metal synergistic contamination in a typical urban-rural river network
Researchers investigated the seasonal co-occurrence of microplastics and heavy metals in urban and rural rivers in a Chinese inland city. They found that both pollutant types were present in all water samples and that microplastics can adsorb heavy metals, potentially increasing the combined environmental risk. The study reveals that river networks connecting urban and rural areas serve as pathways for spreading this dual contamination.
Abundance, Distribution and Drivers of Microplastic Contaminant in Urban River Environments
Researchers surveyed microplastic distribution in urban river environments and identified key drivers of accumulation hotspots, finding that land use, hydrology, and infrastructure factors concentrated microplastics at predictable locations that could inform targeted management interventions.
Occurrence and spatial distribution of microplastic contaminated with heavy metals in a tropical river: Effect of land use and population density
Researchers studied microplastic pollution in Thailand's Chao Phraya River and found that population density and land use strongly influence contamination levels. Urban areas had the highest microplastic concentrations, and many particles were contaminated with heavy metals. The findings suggest that microplastics in rivers can serve as carriers of toxic metals, compounding the pollution risk for downstream communities.
Distribution and variation of metals in urban river sediments in response to microplastics presence, catchment characteristics and sediment properties
Researchers found that microplastic presence, alongside catchment urbanization and traffic activity, is associated with elevated heavy metal concentrations — particularly lead — in Brisbane River sediments, suggesting microplastics act as co-contaminants and vectors for metal pollution in urban waterways.
Lead levels and abundance of microplastics in surface water and sediment along a rural–urban river gradient
Researchers sampled water and sediment along a rural-to-urban river and found microplastics at every location, with concentrations decreasing downstream in surface water but not following a clear pattern in sediment. They also found that higher microplastic levels in sediment were linked to higher lead concentrations, suggesting the two pollutants tend to accumulate together.
