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.
Sampling and Analysis of Microplastics in the Coastal Environments of Sri Lanka: Estuaries of Kelani River to Mahaoya
Microplastic abundance and types were quantified in beach sediments and seawater across nine sites along 42 km of Sri Lanka's western coast, documenting widespread contamination in estuarine and coastal environments.
Abundance and distribution of microplastics in Baturusa watershed of Bangka Belitung Islands Province
Scientists measured microplastic abundance and distribution in the Baturusa River watershed on Bangka Belitung Island, Indonesia, finding plastic particles at all sampling sites. Higher concentrations were found downstream and near populated areas, highlighting the role of human settlements in freshwater microplastic contamination.
Source-to-sink dynamics of microplastics and heavy metals along a land-use gradient in the tropical river system of India
Researchers tracked microplastics and heavy metals along a river system in southern India, finding widespread contamination in both water and sediment. Household waste was identified as a major source, with tiny plastic pellets and beads making up over 80% of the particles found. The study shows how urbanization and human activity drive microplastic pollution in freshwater systems that communities depend on for drinking and farming.
Microplastic Contamination: A Case Study in the Freshwater of Krishna River
Researchers found microplastic contamination in three sites along the Krishna River in India, identifying polypropylene, polyethylene, and polyoxymethylene particles at different pilgrimage locations. The study confirms freshwater microplastic pollution in this important Indian river and demonstrates a sampling approach applicable to future monitoring efforts.
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.

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.
