Abundance and distribution of anthropogenic marine litter in Hatiya and Nijhum Dwip Island, Bangladesh
AI summary Read the abstract
This study surveyed marine litter abundance and distribution on beaches of Hatiya and Nijhum Dwip Islands in Bangladesh, finding plastic as the dominant debris type at 47–61% of items depending on site. The study applied the Clean Coast Index to assess beach quality and recommended both short-term cleanup actions and long-term management frameworks to protect marine biodiversity.
Marine litter is commonly found throughout the oceans, and creates a significant threat to the marine ecosystem. The purpose of the study was to investigate the abundance and distribution of marine litter in Hatiya and Nijhum Dwip Islands, Bangladesh during the post-monsoon and to determine beach cleanliness using the clean-coast index (CCI). A 100-meter line transect was established at each beach, divided into five sections of 20 meters each and positioned perpendicular to the shoreline at the water's edge. A total of 11 types of marine litter were observed. Namar Bazar, Nijhum Dwip Sea beach showed a higher density of litter (0.30 items/m2) compared to Kamalar Dighi, Hatiya (0.13 items/m2). Over 70% of marine litter originated from land-based sources. Plastics were abundant litter at the Kamalar Dighi (46.66%) and Namar Bazar (61.29%). Different size ranges of marine litter were exhibited at the Kamalar Dighi (1.27-25.4 cm) and Namar Bazar (2-74 cm). Based on the mean CCI value, Hatiya and Nijhum Dwip beaches were classified as clean (2.4) and moderate (4.96), respectively. This study, therefore, suggested the conceptual policy framework including short-term (i.e., cleanness of beaches, create awareness, establishment of storages, etc.) and long-term management approaches that would be implemented for sustainable management of marine litter to ensure the conservation of marine biodiversity in the Hatiya and Nijhum Dwip Island

Abundance, Characterization, and Distribution of Marine Litter in Samar, Philippines: A Comparison Between Mainland and Island Beaches
AI summary Read the abstract
A systematic beach litter survey in Samar, Philippines found plastic comprising 86% of mainland beach litter and 60% on island beaches, with shoreline recreational activities as the dominant source, revealing significant differences in contamination between coastal typologies. This study is directly relevant to microplastic research as high plastic litter density on Philippine beaches represents a major source of secondary microplastic generation through UV-driven fragmentation and mechanical weathering in the marine environment.
The first assessment of marine litter on Somalian coast: The case of Liido Beach, Mogadishu
AI summary Read the abstract
This first assessment of marine litter on Somalia's Liido Beach found nearly 120,000 items, with plastics accounting for 89% of debris and a mean density of 6.25 items per square meter. Local recreational and shoreline activities were the dominant pollution sources, and the prevalence of plastic litter poses serious threats to marine biodiversity in the West Indian Ocean.
An Integrated Spatial Assessment of Macro-, Meso-, and Microplastic Pollution Along Cox’s Bazar Beach in Bangladesh
AI summary Read the abstract
Researchers conducted the first comprehensive assessment of macro-, meso-, and microplastic pollution along the full coastline of Cox's Bazar in Bangladesh, sampling 23 stations across tourism, active, and less active beach zones. Plastic abundance varied significantly by zone and land use, with fragments and films as dominant types, reflecting Bangladesh's high plastic waste mismanagement rates.
