ClearPresent 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.
Evidence of microplastics pollution in coastal beaches and waters in southern Sri Lanka

Community awareness and perceptions on microplastics: a case study from Sri Lanka
A community survey in Sri Lanka assessed public awareness of microplastic pollution using convenience sampling across rural and urban areas, finding generally low awareness of microplastics as an environmental and health concern. The results highlight the need for public education campaigns about microplastic risks and regulatory measures.
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.
Microplastics in freshwater sediment in the Indo-Sri Lankan region: a review of methodologies
This review systematically compared the methods used across 34 studies to sample, extract, and identify microplastics in freshwater sediments throughout India, finding no studies addressing the issue in Sri Lanka. Researchers highlighted significant inconsistencies in sampling techniques, extraction procedures, and identification methods across studies, making it difficult to compare results. The study calls for standardized protocols to enable more reliable tracking of microplastic pollution in freshwater sediments across the Indo-Sri Lankan region.
Assessment of Microplastic Contamination in Coastal Waters of Southeast Asia: Implications for Marine Ecosystems and Human Health
This review assessed microplastic contamination in coastal waters across Southeast Asia, synthesizing monitoring data to identify pollution hot spots, dominant polymer types, and the implications for regional marine ecosystem health.
Microplastics in ASEAN region countries: A review on current status and perspectives
This review assessed microplastic research across ASEAN countries, finding that despite contributing heavily to ocean plastic waste, the region accounts for only about 5% of global microplastic studies, with major gaps in human health research.
Aquatic microplastics research in the ASEAN region: Analysis of challenges and priorities
This systematic review analyzes the state of microplastic research across Southeast Asian countries and identifies gaps in how studies are conducted. The researchers found inconsistent methods being used across the region, making it hard to compare results or understand the true scale of contamination. Standardizing how microplastics are measured is important because it will give us a clearer picture of how much plastic pollution people in the region are exposed to.
Airborne Microplastics in Indoor and Outdoor Environments of a Developing Country in South Asia: Abundance, Distribution, Morphology, and Possible Sources
Researchers measured airborne microplastics in indoor and outdoor environments across Sri Lanka, one of the first studies of its kind in a lower-middle-income country. They found that indoor microplastic concentrations were significantly higher than outdoor levels, with fibers being the most common particle type. The study estimates that people in these environments inhale thousands of microplastic particles daily, raising concerns about respiratory health impacts.
Microplastic Content in Non-Point Source And Point Sources of Colombo And Suburbs – Experimental Study on the Impact of Seasonal Variation
Researchers measured microplastic concentrations at point and non-point source locations in Colombo, Sri Lanka, across different seasons. Microplastics were found throughout the surface water network, with concentrations varying by season and location type. The study provides valuable baseline data for a poorly studied region and highlights urban water bodies as major microplastic sources.
A Review of the Current State of Microplastic Pollution in South Asian Countries
This review surveys microplastic pollution across South Asian countries including India, Bangladesh, Thailand, Vietnam, and others. Researchers found microplastics present in water, soil, air, and food across the region, with levels often exceeding those in other parts of the world. The paper highlights the need for better monitoring and regulation in these densely populated countries where exposure may be especially high.
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.
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.
