Microplastic Vulnerability in the Sediments of the Sabarmati River of India
AI summary Read the abstract
Researchers quantified microplastics in sediment samples collected from four sites along India's Sabarmati River, providing baseline data on how these particles accumulate in river-bottom sediments and suggesting that river sediments may serve as long-term sinks for plastic pollution.
The present research work focuses on the quantification of microplastics in Sabarmati river sediments (Gujarat, India). Sediment samples were collected from four different locations along the stretch of the Sabarmati River. Gravimetric analysis was done to quantify...

Microplastic in the Sediment Ecosystem of India
AI summary Read the abstract
This study investigated microplastic accumulation in sediment ecosystems across India, including deep-sea environments, finding widespread contamination across diverse marine habitats. Sediment microplastics are a critical concern because they act as long-term reservoirs that slowly release particles and associated toxins into benthic food webs, ultimately reaching commercially harvested seafood consumed by humans.
Emerging Issue of Microplastic in Sediments and Surface Water in South Asia: A Review of Status, Research Needs, and Data Gaps
AI summary Read the abstract
Sediments and surface waters across South Asia show widespread microplastic contamination, yet significant data gaps and inconsistent monitoring methodologies limit a full understanding of pollution severity in the region. Standardized research frameworks are urgently needed to inform policy and protect populations dependent on these water sources.
Microplastic Detection and Analysis in River Yamuna, Delhi
AI summary Read the abstract
Microplastic contamination was detected at high densities in the Yamuna River in Delhi, with these sub-0.5mm particles found to carry carcinogenic compounds into freshwater systems used by millions of people. The findings highlight the urgent need for pollution controls in South Asian urban waterways, where microplastics pose compounding risks to both aquatic life and human drinking water sources.
Impact and Fate of Microplastics in the Riverine Ecosystem
AI summary Read the abstract
Researchers reviewed the fate, transport, and ecological impacts of microplastics in riverine ecosystems, finding that rivers serve as major conduits for microplastic transfer from terrestrial sources to oceans and that riverine biota face significant exposure-related health risks.
Assessment of Microplastic Contamination in the Surface water of the Bagmati River, Kathmandu Valley
AI summary Read the abstract
Researchers assessed microplastic contamination across 15 sites along the Bagmati River in Nepal's Kathmandu Valley, finding concentrations up to 129 MP per liter with fibers (94%) and polyethylene dominating, and significantly higher concentrations in midstream and downstream zones influenced by urban wastewater and solid waste.
