Microplastic pollution and its implicated risks in the estuarine environment of Tamil Nadu, India
Researchers investigated microplastic pollution across 19 estuaries in Tamil Nadu, India, measuring contamination in water, sediment, and marine organisms.

Microplastics pollution in inland aquatic ecosystems of India with a global perspective on sources, composition, and spatial distribution
Researchers reviewed microplastic contamination in India's rivers, lakes, and wetlands, finding widespread pollution across water, sediment, and wildlife, with concentrations peaking during monsoon season due to runoff.

Presence of microplastics during high rainfall events in the Cauvery River (South India): Ecological risk and cultural practices
Researchers monitored microplastic pollution in the Cauvery River in South India during the monsoon season and found significant contamination at both sampling sites. Analysis revealed that most particles were weathered fibers likely originating from laundry activities, textiles, and fishing gear. The study illustrates how urban development and cultural practices like riverside laundry and religious activities contribute to microplastic pollution in major river systems.
Microplastics pollution in tropical estuary (Muttukadu Backwater), Southeast Coast of India: Occurrence, distribution characteristics, potential sources and ecological risk assessment
Scientists surveyed microplastic contamination in the water and sediments of a tropical estuary on India's southeast coast. They found moderate to high levels of microplastic pollution, with common polymers like polyethylene and polystyrene contributing the most to ecological risk. The presence of trace metals on microplastic surfaces suggests these particles may also serve as carriers for heavy metal contamination in coastal ecosystems.
Impact of flooding events on microplastic distribution from rivers to coastal areas: a case study from Tuticorin, Southeast India
Researchers compared microplastic abundance in river, estuarine, and coastal water and sediment before and after a 2023 flood event in Southeast India. Flood events tripled microplastic abundance in surface water (from 28 to 95 items/L) and increased sediment concentrations 1.5-fold, demonstrating that flooding is a major driver of microplastic redistribution.
Recent Investigation of Characterizing, quantifying, and Contamination of Microplastic in the surface water of Adyar River Estuary, Tamil Nadu, India
Researchers examined microplastic identity, characterisation, spatial distribution, and abundance in surface water samples from the Adyar River Estuary in Tamil Nadu, India, finding polyethylene at 52 percent, polypropylene at 32 percent, and polystyrene at 16 percent across 12 sampling sites totalling 82 microplastic items.

Researchers assessed the abundance and distribution of microplastics in surface water and sediments along the Attanagalu River in Sri Lanka, identifying key pollution sources and transport pathways. The study found elevated microplastic concentrations linked to urban and agricultural land use, underscoring the role of freshwater systems in conveying terrestrial plastic pollution to the ocean.
The seasonal variation and ecological risk of microplastics in the Lower Ganges River, Bangladesh
Researchers characterized seasonal variation in microplastic abundance and polymer composition in the lower Ganges River, finding that monsoon flows dramatically increase microplastic loads and that dry season concentrations reflect local urban pollution.
