Researchers assessed microplastic contamination in water, sediment, and commercially important fish along the Malabar coast in India. They found microplastics in all sample types, with the highest concentrations in fish gastrointestinal and gill tissues, predominantly consisting of fragments and fibers of common plastics like HDPE, PET, and nylon. The study points to direct discharges, runoff, and poor wastewater management as key sources, underscoring the need for regulatory measures to protect both marine ecosystems and the people who consume seafood from the region.

Microplastic surveys in the coral reef environments of the Gulf of Mannar, India found that polyethylene and polypropylene were the dominant polymers, with land-based sources being the main contributor and pollution load indices indicating moderate to high ecological risk.
Holistic assessment of microplastics in various coastal environmental matrices, southwest coast of India
A comprehensive assessment of microplastic pollution along the southwest coast of India analyzed multiple environmental matrices including water, sediments, and biota, finding plastic contamination throughout coastal systems. The holistic approach revealed how microplastics move through coastal food webs and identified fishing and tourism activities as key local sources.

The Presence of Microplastics in High-Demand Seafood Crustaceans of the Gulf of Mannar Coast: An Insight into Seafood Quality
Researchers found microplastics in all environmental samples including sand, sediment, seawater, and the gut and gills of shrimps and crabs from three sites along the Gulf of Mannar coast in Tamil Nadu, India. Coloured polyethylene fragments and polyvinyl chloride were the most prevalent types, with fish landing centres exhibiting the highest plastic pollution levels, raising significant concerns about seafood quality.
