Initial examination of marine microplastics along Jaffna Peninsula’s coastal stretch in the Palk Strait, northern Sri Lanka
Microplastics are pervasive pollutants in marine ecosystems worldwide and are increasingly recognized as a significant environmental threat.

| description | Microplastics are pervasive pollutants in marine ecosystems worldwide and are increasingly recognized as a significant environmental threat. Sri Lanka, an island nation, is not exempt from this issue. While microplastic pollution has been extensively studied in the southern and western parts of Sri Lanka, limited data is available for the northern coastal regions. This first quantitative study aimed to assess the concentration of microplastics on three northern beaches: Mathagal, Point Pedro, and Charty Beach. This study reveals substantial microplastic contamination, with an average abundance of 11.06 ± 6.06 items/m

. The predominant size range of microplastics was 3 to 4 mm (32%). The most common shapes identified were fragments (58%), pellets (17%), and foam (10%), with the primary colours being white (42%), blue (26%), and green (21%). Polyethylene (53%) and polypropylene (18%) were the most prevalent polymers found. Among the beaches studied, Point Pedro had the highest pellet pollution index (PPI), although all three beaches were categorized as having a “very low” PPI level (0.0 |
