ClearOccurrence 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.
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.
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.
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.
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.
Microplastic Pollution, A Threat to Human Health: A Case Study at Thoothukudi, South India
A field study at Thoothukudi, a coastal city in southern India, found microplastics in beach sediments at all seven sampling sites, with fibers and fragments being the most common forms. The results highlight that microplastic pollution is reaching even relatively understudied coastlines in South Asia, with implications for the health of local marine ecosystems and fishing communities.
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.
The Occurrence of Microplastics in the Gut Contents of Selected Estuarine Fishes of Southern Kerala, India
A two-year survey of estuarine fish in southern Kerala, India, found microplastics — predominantly polypropylene, polyethylene, and polystyrene — in the stomachs of multiple commercially consumed species. The study documents spatial and seasonal variation in contamination levels, raising concern about human dietary exposure to microplastics through fish consumption in Indian coastal 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.
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.
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.
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.
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.
