Microplastic intrusion into the zooplankton, the base of the marine food chain: Evidence from the Arabian Sea, Indian Ocean
Microplastics were detected across diverse zooplankton groups in the Arabian Sea basin, with fiber-type particles most prevalent, demonstrating that microplastics have entered the base of the marine food chain in open ocean waters. The study establishes baseline contamination levels and highlights zooplankton as sentinels for microplastic pollution monitoring.
An assessment of microplastics in the ecosystem and selected commercially important fishes off Kochi, south eastern Arabian Sea, India
Microplastics were found in coastal waters, sediment, and the guts of five commercially important fish species off Kochi, India, including sardines and mackerel, with polyethylene and polypropylene the dominant polymer types. The study establishes baseline contamination data for the southeastern Arabian Sea and highlights pelagic fish species as vectors of plastic pollution to human consumers.

Researchers assessed microplastic accumulation in Arabian Sea fish species, developing optimized digestion protocols and characterizing polymer types to trace contamination sources, finding widespread microplastic ingestion across multiple commercially important fish species.
Microplastic occurrence in selected aquatic species of the Persian Gulf: No evidence of trophic transfer or effect of diet
Researchers examined microplastic contamination in six fish species, one mollusk, and three crustacean species from the Persian Gulf, finding no evidence of trophic transfer of microplastics or dietary effects on contamination levels across species.
Ingestion of microplastics in commercially important species along Thoothukudi coast, south east India
Researchers found microplastics in the guts of 12 commercially important marine species along India's Thoothukudi coast, with herbivores showing the highest ingestion rates and evidence of biomagnification across trophic levels, suggesting feeding habits — not habitat or body size — drive microplastic accumulation.
Microplastics in the environment and in commercially significant fishes of mud banks, an ephemeral ecosystem formed along the southwest coast of India
Researchers found marked spatio-temporal variability in microplastic distribution across surface waters, sediments, and fish gastrointestinal tracts in the Alappuzha Mud Banks of southwest India, with MP concentrations peaking during the monsoon mud bank period at mid-water depths.
Study of feeding biology and diet-associated microplastic contamination in selected creek fishes of northeastern Arabian Sea: A multi-species approach
Researchers studied the feeding biology and diet-associated microplastic contamination of selected fish species, finding that feeding habits directly influence the quantity and type of microplastics ingested. The results demonstrate that trophic position and prey preferences are key predictors of microplastic exposure in wild fish.
Microplastics in seawater and zooplankton: A case study from Terengganu estuary and offshore waters, Malaysia
Researchers collected seawater and zooplankton samples from Malaysian estuarine and offshore waters and found microplastics in both matrices, with zooplankton containing MP at higher concentrations than surrounding water, suggesting active uptake rather than passive ingestion during feeding.
Microplastics in fishes of commercial and ecological importance from the Western Arabian Gulf
Researchers examined microplastics in the gastrointestinal tracts of nine commercial fish species from the Saudi EEZ of the Arabian Gulf across coastal, pelagic, and reef habitats, finding a relatively low overall contamination rate (0.057 items per fish) but with variation by species and habitat.
Occurrence and ingestion of microplastics by zooplankton in Kenya's marine environment: first documented evidence
Researchers documented the first evidence of microplastic ingestion by zooplankton in Kenyan coastal waters, finding an average of 110 microplastic particles per cubic metre at the sea surface, with 129 particles recovered from zooplankton including chaetognaths, copepods, amphipods, and fish larvae. Filaments dominated both water and ingested microplastics, comprising 76% and 97% of their respective compositions.
Microplastic contamination in Kerala's coastal ecosystems: a review of sources, distribution, and ecological implications
Researchers reviewed microplastic contamination in Kerala's coastal waters and sediments, finding concentrations as high as 200 particles per liter in some areas, with pollution disrupting mangrove and coral reef ecosystems, entering the food chain through seafood, and posing inflammation and endocrine disruption risks to humans.
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.
A critical review on various trophic transfer routes of microplastics in the context of the Indian coastal ecosystem
This review examines how microplastics accumulate along the Indian coastline through ingestion and bioaccumulation across species including plankton, fish, turtles, and seabirds. The findings highlight India's coastal biodiversity as being at significant risk, with implications for the millions of people who rely on marine fisheries for food.
Microplastic prevalence in epipelagic layer: Evidence from epipelagic inhabiting prawns of north-west Arabian Sea
Researchers assessed microplastic contamination in ten commercial prawn species from the northwest Arabian Sea off Gujarat, India. The study found an average of 590 microplastic particles across gastrointestinal tracts, with significant variation between species and harbors, highlighting concerns about microplastic transfer through commercially important seafood.
Does the microplastics ingestion patterns and polymer composition vary across the oceanic zones? A case study from the Indian coast
Researchers examined microplastic ingestion in 27 species of deep-sea fish from the Central Indian Ocean and found contamination in 19 of them, with PET being the most common polymer. The study suggests that feeding behavior, rather than habitat depth or trophic level, is the primary factor influencing how much microplastic deep-sea fish ingest, and proposes these fish could serve as indicators for monitoring deep-sea plastic pollution.
Distribution of Microplastics in Coastal Waters and Their Implications for the Marine Food Chain
Researchers sampled surface water, sediments, and marine organisms from urban, industrial, and conservation coastal zones in Indonesia to assess microplastic distribution and food chain implications. Industrial zones had the highest microplastic concentrations, and filter feeders accumulated more particles than fin fish, indicating distinct exposure pathways through the marine food web.
The extent of microplastic pollution along the eastern coast of India: Focussing on marine waters, beach sand, and fish
Researchers assessed microplastic contamination across water, sand, and fish from seven major beaches along India's eastern coast, finding widespread pollution dominated by polyethylene and polystyrene with hazard indices indicating potential ecological risk.

Microplastics in the sediments along the eastern Arabian Sea shelf: Distribution, governing factors and risk assessment
Researchers mapped microplastic distribution in sediments along the eastern Arabian Sea shelf across seven coastal transects, finding the highest concentrations off Mumbai at 2500 particles per kilogram. The study found that northern shelf regions had greater contamination than central and southern areas, with microplastic distribution influenced by proximity to urban centers, river inputs, and ocean currents.
Microplastic ingestion by zooplankton in surf zone waters of sandy beaches: Are copepods potential reservoirs of these emerging pollutants?
Researchers investigated microplastic ingestion by tiny zooplankton species in the surf zone of Atlantic beaches in southern Brazil. They found microplastics in the water at concentrations up to 1,750 items per cubic meter, with fibers being the most common type, and confirmed that copepods were ingesting these particles. The study suggests that zooplankton in turbulent nearshore waters may act as reservoirs that introduce microplastics into marine food webs.
