Microplastics contamination, polymer – associated hazard, and dietary exposure in commercially important crustaceans from the Palk Strait, Southeast coast of India
AI summary Read the abstract
Scientists found tiny plastic bits, called microplastics, inside shrimp and other crustaceans caught off India's coast. This matters because these are popular seafood items, meaning people eating them may unknowingly be consuming plastic too. The study also identified which plastic types posed greater potential health risks, helping guide future food safety efforts.
Microplastic (MP) contamination in commercially important crustaceans is a growing environmental and food-safety issue. MP abundance, morphological characteristics, polymer composition, polymer hazard index (PHI), and estimated dietary exposure were examined in Penaeus semisulcatus, P. mon...

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.
Assessment of microplastic contamination in clams and shrimp from estuarine environments of Goa: implications for environmental health and food safety
AI summary Read the abstract
Researchers examined clams and shrimp from estuarine environments in Goa, India, and found microplastics present in both species and their surrounding waters, with shrimp from one site showing particularly high contamination and bioaccumulation. The particles were predominantly polyamide, polyethylene, and polystyrene fibers and fragments, likely originating from fishing, tourism, and waste disposal activities. The findings raise concerns about food safety for local and tourist populations who regularly consume seafood from these coastal areas.
Microplastic ingestion and retention in penaeid shrimp from the Arabian Sea
AI summary Read the abstract
Researchers examined the digestive tracts of four commercially harvested shrimp species from the Arabian Sea coast of India and found microplastics in all four, including fibers, pellets, spheres, and fragments made of polyethylene, polystyrene, and other common plastics — providing baseline contamination data for an important seafood source.
Accumulation of microplastic in edible marine species from North Kerala, India
AI summary Read the abstract
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 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.
