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.
The widespread pollution of aquatic environments by microplastics (MPs) has garnered significant attention. However, there remains a dearth of studies examining the external (body washout) and internal accumulation (gut) of MPs in fish populations within stake net...

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.
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.
Microplastic Contamination in the Ramsar-Designated Pallikaranai Wetland, Southern India
AI summary Read the abstract
Scientists found tiny plastic bits (from things like packaging, bottles, and synthetic fabrics) buried in the mud and water of a protected wetland in southern India, likely washed in from nearby cities' trash. While this study looked at the wetland itself rather than people, it matters because these wetlands filter water and support wildlife that's part of the food chain—so plastic pollution here can work its way up to the fish and water supplies humans depend on. The findings are a reminder that mismanaged waste doesn't just disappear; it accumulates in the ecosystems we rely on for clean water and food.
Microplastic contamination in Ashtamudi short neck clam Marcia recens and its implications for ecosystem and human health
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.
Microplastic Pollution in Commercially Important Seafood from Chandipur, Bay of Bengal, East Coast of India: A Detailed Risk Analysis
AI summary Read the abstract
Scientists tested popular fish and shrimp from India's Bay of Bengal coast and found tiny plastic particles (microplastics) not just in the guts, but also in the muscle tissue — the part people actually eat. Some of these plastics, including PVC and PET (common in pipes and bottles), were found at levels considered hazardous, and contamination was worse during monsoon season, likely due to rain washing plastic waste into the sea. This matters because eating seafood is a direct way microplastics and their chemicals could enter our bodies, and this study is among the first to measure that risk in this specific region.
