Item Abundance and characterization of microplastics in Dawkinsia filamentosa inhabiting the Kothmale reservoir, Mahaweli upper catchment in Sri Lanka(Institute of Chemistry Ceylon, 2025-05) Jayasekara H. N. L; De Silva D. S. M; Amarathunga A. A. D.; Walpita C. NMicroplastics (MP) are plastic particles less than 5 mm in size, and it is an emerging pollutant with a rising global concern. Reservoirs are considered an enclosed aquatic environment, and the presence of MP in the freshwater environment poses a serious risk to its biota.Item Assessment of microplastic pollution in water and sediment: a preliminary study in Uma-oya and Badulu-oya sub-catchments of the Mahaweli river, Sri Lanka(Institute of Chemistry Ceylon, 2025-05) Chandana N. T; De Silva D. S. M; Amarathunga A. A. D; Hettige N. D; Perera H. A. C. CMicroplastics (≤5 mm) are emerging global pollutants. Their accumulation in freshwater ecosystems converts these into contaminant sinks, making microplastic pollution a significant global issue.Item Microplastics in Sri Lankan freshwater ecosystems: abundance, characterization, and sources in two major reservoirs(Institute of Chemistry Ceylon, 2025-05) Lahiru A. A. S; De Silva D. S. M; Amarathunga A. A. D; Narangoda S. R. C. N. KMicroplastic (MP) contamination is a global concern, yet its impact on Sri Lanka’s reservoirs remains largely unexplored. These reservoirs provide vital ecosystem services and regulate river runoff.
