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.
Microplastic Contamination in the Wild Caught Crab Podophthalmus Vigil (Fabricius, 1798) from Ganjam Coast, Odisha, India: First Report
AI summary Read the abstract
This first-ever study of microplastic contamination in the sentinel crab Podophthalmus vigil from India's Ganjam Coast found fibers, fragments, and granules — primarily polypropylene, polystyrene, and polyethylene — in the gills, gut, and muscle tissue, with gills showing the highest concentrations. The contamination of commercially harvested crabs across multiple tissue types, including edible muscle, demonstrates a direct microplastic exposure pathway to human consumers of coastal seafood.
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 The paper has since been retracted from the literature.
Smaller fibrous microplastics exert stronger multi-level effects on the intertidal mud crab (Macrophthalmus japonicus)
AI summary Read the abstract
Tiny plastic fibers, smaller than a grain of rice, turned out to be more harmful to mud crabs than larger plastic fibers, causing more deaths, damage to their gills, and buildup in their bodies. Since these crabs are part of the food chain that ends up on our plates, this research suggests that smaller microplastic fibers in our oceans could pose a bigger risk to seafood safety than previously thought.
Assessment of microplastic hazards in Penaeus vannamei shrimp in a typical estuary of China: polymer composition, risk assessment, and health implications
AI summary Read the abstract
Researchers assessed microplastic contamination in whiteleg shrimp from the Jiulong River estuary in China, finding five polymer types at 0.46 particles/g, with PVC comprising only 5.52% by count but contributing 98.11% of the total hazard risk index due to its toxic chemical additives. The disproportionate hazard posed by PVC despite its low abundance in farmed shrimp has direct food-safety implications, as commercially important shellfish in estuarine aquaculture systems are accumulating high-risk plastics consumed by people globally.
