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 The paper has since been retracted from the literature.
Microplastic (MP) pollution has increased drastically due to improper plastic waste management. The present study aimed to investigate the MPs contamination in the commercially important brachyuran crab Portunus segnis of Gujarat State, India. One hundred fifty crab specimens were collected from three principal fishing harbors in Gujarat. The collected specimens were analyzed for MP extraction using a previously documented protocol. The chemical composition of extracted MPs was assessed with ATR-FTIR. The average abundance of MPs contamination was recorded as 0.82 ± 0.58 MPs/g and 2.02 ± 1.48 MPs/individual. Findings of Contamination Factor (CF) revealed that study site Jakhau was identified as a low-contamination site, while Okha and Veraval were considered moderately contaminated. The H index has identified study sites Jakhau and Veraval as class IV risk categories, while study site Okha fell into the class V risk category. PRI value revealed the very high contamination of MPs in all the study sites. The guts were recorded as being more contaminated with MPs than the gills. The average abundance of MP contamination in males (0.77 ± 0.14 MPs/g in Jakhau, 1.19 ± 0.77 MPs/g in Okha, and 0.82 ± 0.43 MPs/g in Veraval) was recorded higher than in females (0.33 ± 0.11 MPs/g in Jakhau, 0.8 ± 0.49 MPs/g in Okha, and 0.75 ± 0.41 MPs/g in Veraval) in all the study sites. The average abundance of MP contamination varied significantly between males and females. Fibers were found dominantly in all study sites, followed by fragments, films, and foams. Black and blue-colored MPs with 1-2 mm sizes were found more abundantly. The chemical composition of the extracted MPs revealed polyethylene, nylon, polyurethane, and polystyrene as polymer compositions. Overall, the present study highlighted the MP contamination in commercially important crabs that can be used as a basis for further studies on ecotoxicology and seafood safety.

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.
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.

Researchers examined microplastic contamination in two species of commercially important shrimp from the Northern Bay of Bengal in Bangladesh. They found microplastics in the gastrointestinal tracts of both species, averaging about 3.4 to 3.9 particles per gram, predominantly black filaments and fibers made of polyamide and rayon. Note: this paper has been retracted by the journal.
