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.

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. 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.
