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.

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.

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.
