ClearEnvironmental risk assessment of heavy metals and microplastics in marine biota along Gujarat coastline, India
Researchers assessed environmental risks from both heavy metals and microplastics in marine organisms collected along the Gujarat coastline in India, measuring contamination levels in multiple species. Combined contamination elevated ecological risk indices above safe thresholds at several coastal sites.
Integration of microplastics and heavy metals in the potential ecological risk index: Spatial pollution assessment of sediments in the inner Gulf of Thailand
Researchers assessed the spatial distribution of microplastics and heavy metals in surface sediments of the inner Gulf of Thailand, finding an average of nearly 1,400 microplastic pieces per kilogram with the highest concentrations near river mouths. They developed an integrated ecological risk index combining microplastic and heavy metal contamination, revealing that areas near river estuaries face moderate to considerable combined pollution risk. The study demonstrates the importance of evaluating microplastics alongside other contaminants for comprehensive environmental risk assessment.

Researchers assessed microplastic pollution across water, sediment, fish, crab, and snail from Bangladesh's Buriganga River, finding widespread contamination with fibers and fragments along with elevated heavy metal concentrations on microplastic surfaces.
The combined exposure of microplastics and toxic contaminants in the floodplains of north India: A review
This study examined combined microplastic and toxic contaminant pollution in floodplain soils and biota, focusing on how microplastic surfaces transport and concentrate co-pollutants. Evidence showed that microplastic surfaces act as active vectors for toxic chemicals rather than inert carriers, increasing exposure risks to floodplain organisms.
A comprehensive assessment of macro and microplastics from Rivers Ganga and Yamuna: Unveiling the seasonal, spatial and risk factors
This study provides the first comprehensive look at plastic pollution in India's Ganga and Yamuna rivers, finding microplastics in surface water, deeper water, and sediments at all sampling locations. Contamination was higher during the wet season, and some of the polymers found are classified as hazardous. The millions of people living in the Indo-Gangetic Plain may be at risk from both direct water contact and indirect exposure through the food chain.
Ecological and health risk assessment of heavy metals bioaccumulation in Ganges fish near Varanasi, India
Not relevant to microplastics — this study measured heavy metal (lead, manganese, chromium, cadmium) contamination in the Ganges River at Varanasi and in fish caught there for human consumption, finding metal levels well above safe drinking water standards and significant bioaccumulation in fish tissue.
Microplastic in upper Himalayan Ganga river: Occurrence, seasonal dynamics and ecological risk
Researchers quantified microplastics at 19 sites across the upper Himalayan Ganga River over six months, finding concentrations of 100–1,550 particles per liter in water and rising contamination levels downstream toward densely populated cities, with fibers, polyethylene, and post-monsoon conditions dominating the pollution profile.
Characterization of microplastics in commercially valued Gangetic fishes and its exposure assessment on humans
Researchers characterized microplastics in commercially sold fish from the Ganges River in India, finding plastic contamination across multiple species and providing an initial exposure assessment for human consumers who rely on freshwater fish as a primary protein source.
Metal adsorption by naturally aged polymers in the river ganga: An environmental assessment
Researchers measured the adsorption of metals onto naturally aged microplastic polymers collected from the Ganga River, examining how plastics weathered under real environmental conditions accumulate heavy metals. Aged microplastics from the river showed significant metal adsorption capacity, suggesting they act as vectors transferring metals to aquatic organisms through the food chain.
Heavy Metals and Microplastics as Emerging Contaminants in Bangladesh’s River Systems: Evidence from Urban–Industrial Corridors
This review examines heavy metal and microplastic contamination in two major rivers in Bangladesh that run through heavily industrialized areas. Extremely high levels of toxic metals like chromium, lead, and cadmium were found alongside widespread microplastic pollution, mostly from textile and leather factories. The contamination poses serious health risks to the millions of people who rely on these rivers for drinking water, fishing, and daily life.
Synergistic Impacts of Microplastics and Heavy Metals in Aquatic Environments and Strategies for Mitigation
This review examines the combined pollution of aquatic habitats by heavy metals and microplastics, covering their widespread distribution from polar regions to deep-sea sediments and the ecological risks of their interaction.
