Sources, spatial distribution and abundance of marine debris on Thondi coast, Palk Bay, Southeast coast of India
AI summary Read the abstract
Researchers surveyed the abundance, distribution, and types of marine debris on Thondi coast in southeast India, including the Clean Coast Index as a measure of beach cleanliness. The study found significant marine debris driven by fishing, aquaculture, and poor solid waste management in the area.
Abstract Background: The Thondi coast is a rich source of valuable natural marine resources, as well as many socioeconomically significant activities like agriculture, aquaculture, and fishing. The area receives an excess of untreated solid and liquid waste as a result of these activities. The study focus on the abundance, distribution, and status of the Clean - Coast Index (CCI) of marine debris from the Thondi coast, Palk Bay, Southeast coast of India. This research was the first to assess the type and quantity of marine debris on the Thondi coast. Results: A total of 1636 marine debris items/m2 and 4.09 density of the items/m2 were determined in the marine debris: plastics (77.49%), cotton swabs (8.62%), cigarette butts (10.15%), and food containers (3.73%). From the result, the CCI is ranged between 4.25 (clean) and 20.4 (extremely dirty) with a mean of 8.92 (moderate) in the Thondi coast assessed. Conclusion: These studies were conducted for the first time in this region. Finally, the high CCI value of 20.4 in the coast indicates that the marine debris pollution levels are high at the time of sampling in the middle part of the Thondi coast (most of the beach is covered with plastic) due to land – based marine debris (62.45%), sea – originated marine debris (21.14%) and unknown sources (16.41%) of the items. Our findings serve as a baseline for potential evaluations of marine environments. Input prevention should be the goal of management efforts, which include proper waste management, plastic recycling, and stringent penalties for illegal waste dumping.

Researchers surveyed eight sandy beaches along the Tuticorin district coast in southeast India for macro-, meso-, and microplastic debris. The study found microplastic concentrations ranging from 25 to 83 items per square meter, with contamination levels varying by site depending on the intensity of fishing and other human activities, confirming widespread plastic pollution along India's southeastern coastline.
Fishing litter dominates the litter along the beaches of Palk Bay, Southeastern of India
AI summary Read the abstract
This study assessed marine litter abundance, composition, and sources at ten fishing beaches along Palk Bay on the southeast coast of India, collecting 4,227 items at an average density of 0.70 items/m2. Plastic was the dominant material (84.54%), with the majority of litter originating from fishing activities—including strings, cords, lines, and gear. Social media data revealed 25 olive ridley turtles entangled in fishing litter between 2018 and 2020, highlighting the wildlife impacts of unmanaged fishing waste.
