Detection of Microplastics in Commercially Important Shrimp via Chemical Digestion and Optical Microscopy
AI summary Read the abstract
Researchers detected microplastics in commercially important shrimp species using chemical digestion and optical microscopy, quantifying particle characteristics and raising food-safety concerns about human exposure through seafood consumption.
In aquatic ecosystems, plastics degrade, transforming into smaller particles called microplastics (MPs), which can easily be mistaken for food and ingested by aquatic fauna, contaminating it. Many of these contaminated animals are of great commercial interest and are part of the human food cha...

Detection of Microplastic in Seafood
AI summary Read the abstract
This review synthesizes research on the detection of microplastics in seafood, examining analytical methods and the prevalence of plastic contamination across commercially important marine species. Seafood is among the most direct dietary pathways for human microplastic ingestion, making reliable detection methods essential for quantifying health risks and informing food safety standards.
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.
Microplastics in Acetes shrimps from the southeastern coast of Bangladesh
AI summary Read the abstract
Researchers analyzed microplastic contamination in two Acetes shrimp species from Bangladesh's southeastern coast, finding an average of 0.078–0.102 particles per shrimp, predominantly polyethylene and polypropylene fibers identified via ATR-FTIR. The findings demonstrate that even small zooplankton-level seafood consumed by millions carries microplastics, highlighting the dietary exposure pathway through marine food webs.
A Rapid Method for Screening Microplastic in Seafood Using Nile Red (NR) and Fluorescence Preceding Spectroscopic Polymer Analysis
AI summary Read the abstract
Researchers developed a faster method for detecting microplastics in seafood using a fluorescent dye called Nile Red, allowing particles as small as 0.02mm to be identified more quickly and cost-effectively — an important step for food safety monitoring given how widely seafood is consumed.
A Comprehensive Investigation of Microplastic Contamination and Polymer Toxicity in Farmed Shrimps; L. vannamei and P. monodon
AI summary Read the abstract
Researchers found high microplastic contamination in two commercially farmed shrimp species from Sri Lanka, with concentrations averaging nearly 5 particles per gram in whiteleg shrimp, and showed via zebrafish embryo testing that polyethylene-nylon combinations caused significant harm to hatching, survival, and heart function.
