ClearTracing the Plastic Tide: Assessing Microplastic Abundance and Distribution along the Attanagalu River in Sri Lanka
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.
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.

Water quality and floating microplastics pollution along Southern to Northwestern Coast, Sri Lanka
Researchers surveyed microplastic levels and water quality at 12 coastal sites along Sri Lanka's western and southern coast, finding microplastics present at all locations with fibers being the dominant form. The study also found correlations between microplastic abundance and certain water quality parameters, suggesting that areas with poorer water quality tended to have higher plastic loads. The research adds to growing evidence that South Asian coastal waters are significantly contaminated with microplastics, with potential implications for marine food webs and fishing communities.
Sampling and Analysis of Microplastics in the Coastal Environments of Sri Lanka: Estuaries of the Kelani River to Mahaoya
Microplastics were found in both beach sediments and coastal seawater along 42 kilometers of Sri Lanka's western coastline, with polyethylene, polypropylene, and polystyrene being the most common types. The results document significant plastic contamination along the coast of a densely populated South Asian nation, raising concerns about exposure for coastal communities and marine life in the Indian Ocean region.
Quantification and morphological characterization of plastic litter (0.30–100 mm) in surface waters of off Colombo, west coast of Sri Lanka
Surface water off Colombo, Sri Lanka, contained an average of 140 plastic items per square meter, with 99.6% classified as small microplastics under 1 mm in size. Filament-shaped plastics dominated and concentrations were highest near the most populated coastal districts, reflecting urban plastic pollution inputs.
Present Status of Microplastic Pollution Research Data in Sri Lanka and Microplastic Risk Mitigation Solutions; Lessons from a Global Policy Context
This review synthesizes the present status of microplastic pollution research data in Sri Lanka and evaluates risk mitigation solutions within a global policy context. The paper assesses monitoring data across aquatic environments and proposes lessons from international policy frameworks to strengthen Sri Lanka's response to microplastic contamination.
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.
Spatiotemporal variation in microplastic contamination along a subtropical reservoir shoreline
Researchers tracked microplastic contamination along the shoreline of a subtropical reservoir over two years and found that microplastic abundance was higher near urban areas and varied with season, with storm-related inputs creating significant temporal spikes.
Microplastic Pollution in Urban Lake Phewa, Nepal: The First Report on Abundance and Composition in Surface Water of Lake in Different Seasons
Researchers conducted the first survey of microplastics in Lake Phewa, a major freshwater lake in Nepal, finding plastic particles in surface water across all seasons. Fiber microplastics were most abundant, consistent with laundry and textile sources. This study provides baseline data for microplastic monitoring in Nepal, where freshwater microplastic research has been largely absent.
Seasonal variations in the abundance and distribution of microplastic particles in the surface waters of a Southern Indian Lake
Researchers documented seasonal variations in microplastic abundance in a southern Indian lake, finding higher concentrations during monsoon season due to stormwater runoff, with fibers and fragments as the dominant particle types linked to nearby urban and agricultural activities.
Microplastic occurrence and densities in small subtropical reservoirs of Southern Africa
Researchers measured microplastic levels across seasons in small reservoirs in southern Africa, finding that microplastic concentrations were higher during the dry season and in reservoirs near areas with greater human activity.
