Microplastics in the edible and inedible tissues of Mugil cephalus from Ashtamudi Lake, a Ramsar site in Kollam, Kerala, India
AI summary Read the abstract
Researchers found microplastics in both edible and inedible tissues of mullet (Mugil cephalus) from Ashtamudi Lake, a protected Ramsar wetland in India, with over half of sampled fish containing plastic particles, signaling a food safety concern for communities dependent on this fishery.
Microplastics are considered as an emerging global issue due to its detrimental effects on natural ecosystem.These microplastics have ill-effects on aquatic biota and possible hazards to human health.Contamination of fish by microplastics is a major hazard that requires special focus.We examined the presence of Microplastics in edible and inedible tissues of Mugil cephalus (Mullet) from Ashtamudi Lake, a RAMSAR site.53.33% of the sampled 60 fishes had ingested plastic particles.The average abundance of microplastics was 0.08 ± 0.009 and 0.31 ± 0.016 items/fish respectively in the edible and inedible tissues.The most commonly found MPs were fibre (70.83%).Red and black coloured microplastics were the most commonly ingested particle.Fourier Transform Infra-Red spectroscopy characterisations of the debris revealed, polyethylene as the most abundant polymer type in both edible and inedible tissue.The results point to the possibility of small-scale human ingestion of microplastics through the consumption of filter feeders from this lake.

Microplastic contamination in Ashtamudi Lake, India: Insights from a Ramsar wetland
AI summary Read the abstract
Researchers investigated microplastic contamination in water, sediment, fish, and shellfish of Ashtamudi Lake, a Ramsar-designated wetland in southwest India. They found microplastics present across all sampled compartments of this ecologically and economically important brackish water system. The study raises concerns about potential human exposure to microplastics through locally consumed fishery resources from this important coastal lake.
Microplastic Contamination in Fin and Shellfish from Stake Net Fishery: A Study at Ashtamudi Lake, the Ramsar Site, Kerala, India
AI summary Read the abstract
Researchers found tiny plastic particles (microplastics) both on the surface and inside the guts of fish and shellfish caught in Ashtamudi Lake, a protected wetland in India that supplies seafood to local communities. This matters because when we eat seafood without removing the guts, like small fish or shellfish, we may also be consuming these plastic particles, raising questions about long-term exposure through our diet. The study highlights that even protected, ecologically important waters aren't immune to plastic pollution, which could affect both marine life and the people who depend on it for food.
Microplastics in the edible and inedible tissues of pelagic fishes sold for human consumption in Kerala, India
AI summary Read the abstract
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.

AI summary Read the abstract
Researchers characterized microplastics ingested by the commercially important Ashtamudi clam (Marcia recens) in a Ramsar-protected estuary in Kerala, India, detecting MPs in 22.4% of samples — mainly polypropylene and polyethylene fibres and fragments — raising concerns for the fishing communities and consumers who depend heavily on this species.
Occurrence and Characterization of Microplastics in the Gastrointestinal Tracts of Fish and a Crustacean from the Keralam Coast, Southeastern Arabian Sea
AI summary Read the abstract
Researchers found tiny plastic particles (microplastics) in the stomachs of nearly half of the fish and shrimp they tested from a fishing harbor in India, including popular seafood like mackerel and mullet. These plastics likely come from urban runoff and harbor activity, and since these are commercially sold species, this raises concern that the plastic we dump in the ocean could be making its way onto our dinner plates.
