ClearAssessment 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.
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.
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.
Microplastics in the edible and inedible tissues of pelagic fishes sold for human consumption in Kerala, India
Researchers examined microplastics in both edible and inedible tissues of nine commercially important fish species from Kerala, India. They found that 41% of fish had microplastics in inedible tissues like gills and viscera, while 7% had particles in edible muscle and skin, with filter-feeding fish showing higher contamination than visual predators. The study suggests that human consumption of pelagic fish from this region could result in microplastic exposure, though the quantities found in edible tissues were relatively small.
Occurrence of Microplastics in the Gastrointestinal Tracts of Edible Fishes from South Indian Rivers
Researchers isolated and characterized microplastics from the gastrointestinal tracts of five edible fish species collected from the Kollidam and Vellar rivers in Tamil Nadu, Southern India. They found 315 microplastic particles across 23 fish, dominated by fibers (85.7%) in Kollidam river fish and fragments (14.3%) in Vellar river fish, with particle sizes ranging from 109 to 284 µm, indicating widespread dietary exposure to microplastics in commercially harvested freshwater fish.
Occurrence of microplastics in fishes from two landing sites in Tuticorin, South east coast of India
Microplastics were found in the stomachs of two commercial fish species from markets in Tuticorin on India's southeast coast, with fibers and fragments as the dominant types. The study provides baseline data on microplastic ingestion by market fish in a major Indian fishing hub with implications for human dietary exposure.
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.
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.
Status of Microplastic Accumulation in Water and Sediments of Selected Estuarine Ecosystem of Southern Kerala, India
Researchers measured microplastic levels in water and sediment from estuaries in southern Kerala, India, finding significant contamination in both habitats. The study identifies these coastal estuaries as accumulation zones for microplastic pollution, posing risks to local aquatic life and fishing communities.
Comparison of Presence of Microplastics in Two Edible Fish Species from South India
Researchers compared microplastic contamination in two edible fish species from South India, finding differences in the abundance and types of microplastics between species that likely reflect differences in feeding habits and habitat use.
Microplastic contamination in thirty commercially important fish species: Distribution, polymer composition, pollution indices, and human health risks
Researchers examined microplastic contamination in 600 specimens across 30 commercially important fish species from the Indian coast, finding the highest accumulation in the gastrointestinal tract with carnivorous species carrying the greatest burden. Polyethylene and polypropylene fibers were the dominant particle types, and human health risk assessment showed measurable daily intake from consuming these fish, with pollution indices indicating considerable to medium hazard risk levels.
Accumulation of microplastic in edible marine species from North Kerala, India
Researchers found microplastics in the edible tissues of three popular seafood species (clams, shrimp, and anchovies) from fish markets in Kerala, India. Fibers and fragments were the most common shapes, with polyethylene and polypropylene being the dominant plastic types. Since these species are consumed whole or with minimal processing, the study highlights a direct pathway for microplastic ingestion by people who eat locally caught seafood.
Occurrence of microplastics in gastrointestinal tracts of planktivorous fish from the Thoothukudi region
Planktivorous fish from the Thoothukudi region of southern India were surveyed for microplastic ingestion, with plastics found in a high proportion of the 677 individuals examined across multiple species. The results demonstrate that passive ingestion during filter feeding makes planktivorous fish particularly susceptible to microplastic exposure.
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.
Microplastics accumulation in pelagic and benthic species along the Thoothukudi coast, South Tamil Nadu, India
Researchers surveyed microplastic contamination in the digestive tracts of fish and shellfish along the Thoothukudi coast in southern India. They found microplastics in both open-water and bottom-dwelling species, with bottom-dwellers accumulating slightly more particles, predominantly polyethylene fibers. The findings confirm that microplastic contamination is widespread across marine habitats in the region and underline the need for better plastic waste management.
Microplastics and trace metals in fish species of the Gulf of Mannar (Indian Ocean) and evaluation of human health
Researchers examined microplastics and trace metals in five commercially important fish species from the Gulf of Mannar in the Indian Ocean. They found microplastics in both muscle and intestinal tissues, predominantly polyethylene and polypropylene particles, and estimated that human consumers could ingest 121 to 456 microplastic items per person per year from eating these fish.
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.
