Assessment of Pollution Indices of Microplastic Contamination in Commercially Important Brachyuran Crab (Portunus sanguinolentus)
AI summary Read the abstract
A study of 300 commercially harvested three-spot swimming crabs (Portunus sanguinolentus) from three ports in Gujarat, India, found microplastics in all samples, with two of the three sites classified in the highest risk contamination categories. Fibers dominated, and common packaging polymers including polyethylene and polystyrene were identified, raising food safety concerns for seafood consumers in the region.
Abstract Microplastic (MP) in seafood is a growing area of food safety. In the present study, MP contamination in the commercially important crab,Portunus sanguinolentus,of Gujarat state, India, was assessed. A total of 300 crab specimens were collected from three principal fishing harbors in Gujarat. The collected specimens were analyzed using a previously used methodology. The average abundance of MP was recorded as 0.67 ± 0.62 MPs/g. The pollution indices revealed high contamination and fell under class IV (Jakhau) and V risk categories (Okha and Veraval). Threads were found dominantly. Blue and black-colored MPs with 1–2 mm sizes were recorded dominantly. Polyethylene, Polyethylene tetraphene, polyurethane, polystyrene, and polypropylene were identified as polymer compositions of MPs. Concludingly, the present study gives an insight into the MP in crabs, which can help design further investigations on the toxicity of MPs in seafood.

Ingestion and polymeric risk assessment of microplastic contamination in commercially important brachyuran crab Portunus sanguinolentus
AI summary Read the abstract
Researchers examined microplastic contamination in a commercially important crab species from three fishing harbors in India and found plastics in every location sampled. The crabs contained an average of 0.67 microplastic particles per gram, with polyethylene and polystyrene among the most common types, and pollution levels rated as very high risk at all sites. Since these crabs are widely eaten, the findings suggest that seafood consumers may be regularly ingesting microplastics.
Tissue-specific distribution of microplastics in commercial crab Portunus segnis: a baseline data for sea-food security
AI summary Read the abstract
Scientists found tiny plastic bits (microplastics) in nearly two-thirds of crabs tested from the Gujarat coast in India, with the highest amounts in the gut and gills, but plastic was also found in the muscle tissue that people actually eat. The most common plastics found were polyethylene and nylon, common materials in packaging and fishing gear. While this study didn't test health effects directly, it adds to growing evidence that seafood lovers may be unknowingly consuming microplastics, making crabs a useful early-warning signal for plastic pollution in our oceans and food supply.
RETRACTED: Microplastics occurrence in commercial crab (Portunus segnis) from the western coast of India and pollution indices: First investigation and evidence
AI summary Read the abstract
This retracted study investigated microplastic contamination in commercial crabs (Portunus segnis) from fishing harbors in Gujarat, India, finding an average of 0.82 +/- 0.58 MPs/g and 2.02 +/- 1.48 MPs/individual, with ATR-FTIR used to confirm polymer composition. The paper has since been retracted from the literature.
The Contamination of Microplastic Debris in Blue Swimming Crab Portunus pelagicus (Linnaeus, 1758) from Artisanal Fisheries in the Eastern Gulf of Thailand
AI summary Read the abstract
Researchers collected blue swimming crabs from the Gulf of Thailand and found microplastics in 62.5% of external body parts and 72.2% of internal parts, with fibers dominating and gut tissue showing the highest contamination. The findings indicate widespread MP ingestion in commercially harvested crabs and potential food safety implications.
Microplastics in Scylla Serrata: A baseline study from southwest India
AI summary Read the abstract
Researchers examined microplastic contamination in the mud crab Scylla serrata from mangrove habitats on India's southwestern coast and found an average of about 29 microplastic particles per individual. Fibers were the dominant type, and polypropylene and polyethylene were the most common polymers detected. The study establishes a baseline for microplastic presence in a commercially important crab species, raising questions about potential human exposure through seafood consumption.
