Assessment of Microplastic Pollution Across the Malabar Coast, India
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.
Abundance, characteristics, and risk assessment of microplastics in indigenous freshwater fishes of India
Researchers examined microplastic contamination in five widely consumed freshwater fish species from India and found plastic particles in all specimens, with fibers being the most dominant type. Evidence of microplastics in edible fish tissue indicates translocation from the gut, suggesting a pathway for human exposure through consumption. Risk assessment showed that while microplastic abundance posed a low quantitative risk, the polymer types identified indicated a high hazard potential for the fish species studied.
Microplastic pollution in Vembanad Lake, Kerala, India: The first report of microplastics in lake and estuarine sediments in India
Researchers conducted the first study of microplastics in Vembanad Lake, Kerala, India, finding plastic particles across sampled sites and documenting the types and polymer composition of contamination in this important freshwater ecosystem.

This review examines sources and impacts of microplastic pollution across Indian aquatic ecosystems, documenting widespread contamination in marine and freshwater environments and discussing risks to living organisms given projections that ocean plastic will outweigh fish by 2050.
Characterization of microplastics and its Pollution load index in freshwater Kumaraswamy Lake of Coimbatore, India
This study characterized microplastic abundance and composition in Kumaraswamy Lake, a freshwater body in India, mapping spatial distribution and calculating a pollution load index to assess the extent and risk of microplastic contamination.
Assessment Of Microplastics In Commercially Important Fishes Collected From Thondi Fish Landing Center
Researchers assessed the presence and characteristics of microplastics in commercially important fish species collected from the Thondi fish landing center in India. The study evaluated microplastic contamination levels in fish obtained from a coastal fishing hub, contributing data on the prevalence of plastic particles in seafood relevant to both ecological and human dietary exposure concerns.
Assessment and quantification of microplastic contamination in fishes with different food habits from Beel wetlands
Researchers examined microplastic contamination in fish from freshwater wetlands in India, finding particles in the digestive tracts of all 90 fish sampled across different feeding types. Carnivorous fish accumulated the most microplastics, followed by omnivores and then herbivores, suggesting trophic transfer plays a role. The most common particles were fibers in the 100 to 500 micrometer size range, with polyethylene and nylon as the dominant polymer types.
