Occurrence and human exposure risk of microplastics in commercially important shrimp species from Northeastern Mediterranean Sea
Researchers examined three commercially important shrimp species from the Northeastern Mediterranean Sea and found microplastics in their digestive organs, primarily polyethylene and polypropylene fibers smaller than 500 micrometers. Smaller shrimp tended to have more ingested microplastics relative to their body weight. The study estimates that people who regularly eat these shrimp could be consuming hundreds of microplastic particles per year, highlighting the need for protective measures.
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.
The Presence of Microplastics in High-Demand Seafood Crustaceans of the Gulf of Mannar Coast: An Insight into Seafood Quality
Researchers found microplastics in all environmental samples including sand, sediment, seawater, and the gut and gills of shrimps and crabs from three sites along the Gulf of Mannar coast in Tamil Nadu, India. Coloured polyethylene fragments and polyvinyl chloride were the most prevalent types, with fish landing centres exhibiting the highest plastic pollution levels, raising significant concerns about seafood quality.
Assessment of microplastic contamination in clams and shrimp from estuarine environments of Goa: implications for environmental health and food safety
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.
Occurrence and Characteristics of Microplastics in Wild and Farmed Shrimps Collected from Cau Hai Lagoon, Central Vietnam
Researchers measured microplastic occurrence in the gastrointestinal tracts and tissues of four shrimp species (two wild, two farmed) from a Vietnamese lagoon, finding microplastics in all species and providing baseline data on seafood plastic contamination for this region.
Abundance and characteristics of microplastic in some commercial species from the Persian Gulf, Iran
Scientists examined microplastic contamination in the digestive tracts of five commercially important fish and shellfish species from the Persian Gulf, finding plastic particles in nearly 73 percent of all individuals sampled. Microfibers were the most common type, making up about 58 percent of particles found, and polymer analysis identified polypropylene and polyethylene as the dominant plastics. The study highlights that seafood from the Persian Gulf region is widely contaminated with microplastics, raising concerns about potential exposure for human consumers.
Microplastics assessment in Arabian Sea fishes: accumulation, characterization, and method development
Researchers assessed microplastic accumulation in Arabian Sea fish species, developing optimized digestion protocols and characterizing polymer types to trace contamination sources, finding widespread microplastic ingestion across multiple commercially important fish species.
Comparative analysis of microplastic pollution in commercially relevant seafood across different geographical regions
Researchers analyzed microplastic pollution in commercially important seafood species, characterizing particle morphology and polymer composition across species. The study found microplastics in all species sampled, with differences in contamination levels linked to feeding ecology and habitat.
Microplastic pollution in wild populations of decapod crustaceans: A review
Researchers reviewed the occurrence and characteristics of microplastics found in wild populations of decapod crustaceans including crabs and shrimps. They found that fibrous microplastics smaller than 1 mm were the most commonly detected type, and that edible portions generally contained fewer microplastics than non-edible parts. The review highlights the importance of understanding microplastic contamination in commercially valuable crustaceans for both ecological and food safety assessments.
Microplastic contamination in brown shrimp (Crangon crangon, Linnaeus 1758) from coastal waters of the Southern North Sea and Channel area
Researchers examined brown shrimp caught from the North Sea and found microplastics in their digestive tracts, documenting contamination in a commercially important crustacean consumed widely by humans in northern Europe.
