Sources, spatial distribution, and abundance of marine debris on Thondi coast, Palk Bay, Southeast coast of India
AI summary Read the abstract
Researchers surveyed marine debris abundance and composition on Thondi coast in Palk Bay, India, finding that plastic was the dominant litter type linked to local fishing, aquaculture, and agricultural activities, with seasonal variation in debris loads.
Abstract Background The Thondi coast is rich in valuable natural marine resources and socio-economically 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 focuses 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 is the first research work focused on assessing the type and quantity of marine debris on the Thondi coast. Results A total of 1636 marine debris items/m 2 and their 4.09 concentration of the items/m 2 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 had ranged between 4.25 (clean) and 20.4 (extremely dirty) with a mean of 8.92 (moderate) in the Thondi coast assessed. Conclusion This study was conducted for the first time in this region. Finally, the high CCI value of 20.4 on the coast indicated that the marine debris pollution levels were high at the time of sampling in the middle part of the Thondi coast (most of the beaches are 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 served as a baseline for potential evaluations of the marine environment. Input prevention should be the goal of management efforts, including proper waste management, plastic recycling, and stringent penalties for illegal waste dumping.

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.
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.
Spatial and seasonal variation of microplastics and possible sources in the estuarine system from central west coast of India
AI summary Read the abstract
Researchers collected samples from an estuarine system on India's west coast across two seasons, finding significant spatial and seasonal variation in microplastic abundance — with monsoon season delivering higher loads — and identifying local fishing activities and urban runoff as primary sources.
Morphometric characteristics and spatiotemporal heterogeneity of microplastics on the north-east coast of India
AI summary Read the abstract
Survey of surface waters along the northeast coast of India found microplastics present in all sampled water masses, with higher concentrations during the monsoon season than the post-monsoon period, and fragments and fibers making up the vast majority of particles. The seasonal pattern suggests land-based runoff is a major delivery pathway, with implications for the many coastal communities in the region that depend on these waters for fishing and livelihoods.

Researchers assessed the spatial and seasonal variation of microplastics in sediment and surface water along the Thoothukudi coast in southeastern India. The study found significant differences in microplastic abundance across sampling sites and seasons, with monsoon periods recording the highest concentrations, and conducted an ecological risk assessment of the contamination levels.
