Microplastics in Weras Ganga, Bolgoda North Lake, Sri Lanka: A Reflection of Urban Waste Mismanagement
Researchers analyzed microplastic pollution in a river and lake system near an open waste dump in Sri Lanka and found microplastics present in all water and sediment samples. Over half of the particles were fibers, and smaller microplastics dominated near the dump site, with sediments acting as a major sink for contamination. The study highlights how inadequate waste management practices directly contribute to microplastic pollution in urban waterways.

Researchers measured microplastic concentrations in the Godavari River in India, finding an average of 3.9 particles per liter across six sites, with fibers making up over 80% of particles and polypropylene and polyethylene being the most common polymer types. Urban areas had higher concentrations, and the presence of these plastics in a major river system poses risks to agriculture and human health through contaminated water and food sources.
Effect of inappropriate solid waste on microplastic contamination in Balasore district and its aquatic environment
Researchers surveyed coastal solid waste sites in the Balasore district of India and detected microplastics ranging from nanometers to micrometers using multiple analytical methods, including ICP-OES spectroscopy applied to microplastic detection for the first time in this context. The findings highlight how improper waste disposal in coastal communities directly contributes to microplastic contamination of nearby aquatic environments.
Microplastics in the rivers of Gujarat (India) to the Arabian Sea: assessment of the sources, distribution, and associated environmental risk
Researchers collected water samples from the Damanganga and Tapi rivers in Gujarat, India, and from Dumas Beach, analyzing them for microplastics by µ-FTIR, SEM, and Py-GC-MS. MPs were detected at all sites, with characterization of polymer types, sizes, and shapes providing baseline data on MP contamination in rivers draining to the Arabian Sea and the associated environmental risk.
Microplastic profile and ecological risk assessment of emerging estuarine contaminants in two tourist hotspots of northern Kerala backwaters
Researchers investigated microplastic pollution in sediments and water of two tourist-heavy estuarine systems in northern Kerala, India. They found average concentrations of 187 to 259 particles per kilogram in sediments and 251 to 284 particles per liter in water, with polyamide as the dominant polymer type, indicating high ecological risk driven by tourism, fishing, and poor waste management.
Assessment of Microplastic Pollution in Coastal Belt of Chennai, Tamilnadu
Researchers investigated microplastic contamination in the Adyar and Coovum river estuaries along the Chennai coastline in India. Using FTIR spectroscopy and X-ray diffraction analysis, they confirmed the presence of microplastics in both water and sediment samples. The study adds to the growing evidence that urban coastal areas in developing regions face significant microplastic pollution challenges.
Microplastic surge in the Ariyankuppam river, Puducherry, India: A study on abundance, characterization, and pollution load index
Researchers surveyed microplastic pollution in the Ariyankuppam River in southern India over three months during the post-monsoon period. They found an average of over 136 microplastic particles per kilogram of sediment, with concentrations varying by location and season. The study reveals significant microplastic contamination in a river that flows into the Bay of Bengal, raising concerns about downstream marine pollution.

Impact of a municipal solid waste processing facility on microplastic pollution in Indonesia’s waterways
Researchers quantified and characterized riverine microplastic pollution in the Jangli River in Semarang City, Indonesia, and assessed the contribution of a nearby Municipal Solid Waste Temporary Processing Site (TPS) to MP contamination through water sampling and field observation. The study documents how proximity to solid waste facilities elevates microplastic concentrations in urban waterways.

Assessment of Microplastic Pollution Across the Malabar Coast, India
Researchers assessed microplastic contamination in water, sediment, and commercially important fish along the Malabar coast in India. They found microplastics in all sample types, with the highest concentrations in fish gastrointestinal and gill tissues, predominantly consisting of fragments and fibers of common plastics like HDPE, PET, and nylon. The study points to direct discharges, runoff, and poor wastewater management as key sources, underscoring the need for regulatory measures to protect both marine ecosystems and the people who consume seafood from the region.
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.
