ClearMicroplastic Pollution in the Marine Ecosystem: A Study of Seawater and Fish Samples from Bhaucha Dhakka and Versova Beach, Mumbai Coast
Researchers investigated microplastic contamination in seawater and commercially harvested fish species from two locations along the Mumbai coast in India. They found microplastics in all water and fish samples, with the highest concentrations at a busy port site and in Bombay duck fish. The discovery of microplastics in fish tissues raises concerns about potential implications for fish health and human consumption of contaminated seafood.
Microplastic pollution in coastal ecosystem off Mumbai coast, India
Researchers surveyed microplastic contamination across water, sediment, and marine fish in the coastal waters off Mumbai, India. They found an average of 372 particles per liter in water and 9,630 particles per kilogram in sediment, with pelagic fish species containing up to 9 microplastic items per individual. The study identified eleven different polymer types and emphasizes that microplastic transfer through the food chain underscores the need for processing interventions to reduce contamination in fish destined for human consumption.
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.
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.
Identification and Microscopic Classification of Microplastics in Beach Sediment Sample at Dadar Chowpatty
Researchers identified and microscopically classified microplastics in beach sediment samples from Dadar Chowpatty, Mumbai, India, investigating the composition and scale of micro-pollution at this urban coastal site. The study aims to raise awareness of microplastic contamination that poses risks to coastal fisheries and ecosystems, and discusses approaches for cleaning beach sediments of microplastic particles.
Microplastic contamination in commercial fish species in southern coastal region of India
Researchers examined 220 commercial fish from the southern coast of India over six months and found microplastic contamination in all samples, with an average of 3.2 to 7.6 particles per fish. The most common types were fibers and fragments, primarily composed of polyethylene, polypropylene, polystyrene, and polyamide. The findings indicate that microplastic contamination in commercially valuable fish species is widespread along the Indian coast, raising concerns about food safety.
Microplastics in the foreshore coastal waters, sediment, and coastal fauna of a highly populated megacity - A study on the effect of anthropogenic discharge on clams
Researchers documented microplastic contamination in coastal waters, sediments, and clams across three beaches of a highly populated Indian megacity, finding high abundances of up to 537.5 items per liter in water and significant bioaccumulation in clam soft tissues.
Microplastic contamination from surface waters and commercially valuable fishes of Karachi Coast, Pakistan
Researchers found widespread microplastic contamination in surface waters and gastrointestinal tracts of 15 commercial fish species from Karachi coast, Pakistan, with fibers being the dominant type and higher concentrations near the harbor.
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.
Microplastic contamination in commercially important fish and shellfish from coastal waters of the Bay of Bengal off Chennai, southeast coast of India
Microplastics were detected in commercially important fish and shellfish from the Bay of Bengal off the southeast coast of India, with average ingestion levels varying by species and collection site. The presence of plastic particles in widely consumed coastal seafood raises direct concerns about human dietary exposure to microplastics in the region.
Quantification, identification, and chemical characterization of microplastics (MPs) in commercial fishes from the Palk Strait, Southeast India
Researchers examined microplastics in the tissues and guts of 75 commercially important fish from the Palk Strait in Southeast India, finding an average of 115 particles per individual. Fibers were the most common form at 51%, with polyethylene and polypropylene as the dominant polymers, and particle sizes ranged from 0.1 to 1.0 millimeters. The presence of microplastics in edible fish tissues suggests a potential route of human exposure through seafood consumption.

Evaluation of Microplastic Contamination in Commercially Edible Fresh Water and Marine Fishes Bought from Fish Markets, Tiruchirappalli, Tamil Nadu, India
This Indian study examined microplastic contamination in freshwater and marine fish sold in markets in Tamil Nadu, finding plastic particles in multiple commercially important species. People who regularly eat fish from contaminated markets are likely consuming microplastics as part of their diet.
The presence of microplastics in the digestive tract of commercial fishes off Pantai Indah Kapuk coast, Jakarta, Indonesia
Commercial fish from nine species collected at the Pantai Indah Kapuk coast in Jakarta were dissected for microplastics, with 97.13% of 174 fish containing an average of ~12 particles per individual dominated by fibers and fragments of PE, PP, and PS. The study documents near-universal microplastic contamination in urban coastal fisheries in Indonesia with implications for seafood consumers.
Ecological assessment of microplastic contamination in surface water and commercially important edible fishes off Kadalundi estuary, Southwest coast of India
Researchers documented microplastic contamination in both the surface water and 12 commercially important fish species from the Kadalundi estuary in India. Fibers were the most common type of microplastic found, with contamination levels varying across fish species. The findings are significant because this estuary is Kerala's first community reserve, and the contaminated fish are widely consumed by local populations.
Microplastic (MP) occurrence in pelagic and demersal fishes of Gujarat, northwest coast of India
Researchers examined 400 fish from Gujarat, India and found microplastics in every single fish, with 68% having plastics in their edible tissue. Fibers were the only type found in edible parts, while inedible tissues also contained fragments and films, with low-density polyethylene being the most common polymer. This is the first study of its kind from this region and suggests that people eating fish from these waters are regularly consuming microplastics.
Occurrence of microplastics in epipelagic and mesopelagic fishes from Tuticorin, Southeast coast of India
Researchers investigated microplastic contamination in seawater and six fish species from different ocean depth habitats near Tuticorin, India. The study found microplastics in the gastrointestinal tracts of both epipelagic and mesopelagic fish, with contamination levels varying by species and habitat, suggesting that microplastic exposure extends across different marine depth zones and could affect human exposure through seafood consumption.
Microplastic contamination in commercially important bivalves from the southwest coast of India
Microplastics were detected in water and three commercially important bivalve species along the southwest coast of India, with concentrations varying by species and collection site. The presence of plastic particles in filter-feeding shellfish intended for human consumption raises concerns about dietary exposure.
