ClearSampling 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.
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.
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.
Contamination of microplastics in tropical coral reef ecosystems of Sri Lanka
Researchers investigated microplastic contamination across ten coral reef ecosystems in Sri Lanka, finding microplastics in corals, water, and sediments with fibers and fragments being the dominant types, representing a previously unquantified threat to tropical reef systems.
Microplastic pollution in Marine Protected Areas of Southern Sri Lanka
Microplastic contamination was documented in coastal and lagoon sediments and water within two Marine Protected Areas in southern Sri Lanka, indicating that even protected zones are not shielded from plastic pollution.
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.
Microplastic pollution status in the coral reef ecosystems on the Southern and Western coasts of Sri Lanka during the Southwest monsoon
Researchers investigated microplastic contamination in six coral reef ecosystems along Sri Lanka's southern and western coasts during monsoon season. They found that small blue fibers were the dominant type, and that microplastic levels in corals were strongly linked to concentrations in surrounding water and sediment. The study suggests that while current contamination levels are relatively low, microplastics may still threaten coral health and warrant further monitoring.
Plastics in surface water of southern coastal belt of Sri Lanka (Northern Indian Ocean): Distribution and characterization by FTIR
Researchers investigated plastic pollution in coastal surface waters across 12 regions in southern Sri Lanka, finding an overall mean microplastic density of 17.45 items per cubic metre with filaments as the most common morphology. FTIR characterisation confirmed the polymer types present, with blue-coloured particles being the most abundant across sampling locations.
Initial examination of marine microplastics along Jaffna Peninsula’s coastal stretch in the Palk Strait, northern Sri Lanka
Researchers conducted the first quantitative study of marine microplastic pollution along the coastal stretch of the Jaffna Peninsula in northern Sri Lanka, sampling sediments and water in the Palk Strait to characterize particle abundance, morphology, and polymer types. The study found measurable microplastic contamination across sampled sites, extending the geographic understanding of microplastic distribution in South Asian coastal waters.
Distribution and characterization of microplastics in beach sand from three different Indian coastal environments
Beach sands from three locations on the Indian coast were analyzed for microplastics, finding concentrations of 45–220 particles/kg dry sand with polyethylene (43%) as the dominant polymer, followed by PET and polystyrene. The study establishes baseline contamination data for Indian beaches and demonstrates consistent polymer profiles across geographically distinct coastal environments.
The extent of microplastic pollution along the eastern coast of India: Focussing on marine waters, beach sand, and fish
Researchers assessed microplastic contamination across water, sand, and fish from seven major beaches along India's eastern coast, finding widespread pollution dominated by polyethylene and polystyrene with hazard indices indicating potential ecological risk.
