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.
Plastic particles <5 mm come under the category of microplastics (MPs) that can be primary or secondary in nature. Microplastic pollution is a major concern because the world’s shores served as a major sink. Previously, the researchers focused on marine...

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.
Microplastic Contamination of the Aquatic Environment in the Indian Scenario: A Review
AI summary Read the abstract
Researchers reviewed microplastic distribution and ecological risk across India's aquatic environments, finding polyethylene, polypropylene, and PET as the dominant polymers in water, sediment, and fish — including edible species — with contamination detected even in remote Himalayan locations.
Microplastic (MP) Pollution in the Context of Occurrence, Distribution, Composition and Concentration in Surface Waters and Sediments: A Global Overview
AI summary Read the abstract
Researchers compiled global data showing microplastic pollution is essentially everywhere — in surface waters and sediments worldwide — with some locations finding microplastics in nearly every sample collected, underscoring how pervasive this contamination has become.
Microplastic Pollution in Indian Aquatic Ecosystems: Insights and Implications
AI summary Read the abstract
Researchers documented widespread microplastic contamination across Indian lakes, rivers, and coastal waters — including in remote high-altitude regions like Ladakh — showing that no aquatic ecosystem in the country is untouched, with direct implications for the hundreds of millions of people who depend on these water sources.
Microplastics in River Sediments Around the Dhaka City: A Case Study for Occurrence and Quantification
AI summary Read the abstract
Researchers measured microplastic concentrations in river sediments around Dhaka, Bangladesh, finding widespread plastic particle pollution in one of the world's most densely populated cities — adding to evidence that heavily urbanized river systems are major reservoirs of microplastic contamination.
