Characteristics of Microplastic in Commercial Aquatic Organisms
AI summary Read the abstract
This review examined microplastic occurrence across multiple commercial aquatic species, compiling data on ingestion rates, particle characteristics, and potential risks to seafood safety. The authors identify fish, crustaceans, and bivalves as primary vectors of human dietary exposure to microplastics through seafood consumption.
This study aims to review the occurrence of microplastics in some commercial aquatic organisms. Microplastics are small plastic particles with a diameter of less than 5 mm. Effluent, stormwater, agricultural, and surface runoff introduce microplastic to freshwater basins. Hydrodynamics and hydrology encompass microplastics. River flow speed can cause turbulence and riverbed instability, increasing microplastic concentrations. Fish, shellfish, and crustaceans ingest microplastics in proportion to their quantity in freshwater and marine environments. Human activities cause variations in the form, color, and size of microplastics in the biota. Animals absorb microplastics through trophic transfer. Increased microplastic residence time before ingestion promotes trophic transmission. Lower food concentration and aggregation enhance microplastic retention in zooplankton guts, increasing transmission to higher-trophic-level species. Most studies show that microplastics in biota are discovered in fish and crustacean intestines and bivalve tissues. Microplastic buildup can disrupt live organisms' growth and reproduction, induce oxidative stress, obstruct the digestive system, and damage the intestine. Microplastics may harm people's health if they eat contaminated seafood that contains them, but more research is needed.

Microplastics as contaminants in commercially important seafood species
AI summary Read the abstract
This review summarizes evidence that microplastic ingestion is widespread in commercially important seafood species including mollusks, crustaceans, and fish. Evidence indicates that microplastics can affect physiology, reproductive success, and survival in marine organisms, and may also act as vectors for chemical pollutants. The study highlights the potential for human exposure to microplastics through seafood consumption, though the full health implications remain to be determined.
Occurrence, sources and potential human health risk of microplastics in seafood species
AI summary Read the abstract
Researchers measured microplastic occurrence in seafood products available in local markets, identifying plastics in multiple species including fish, shrimp, and bivalves, and estimated potential human dietary intake based on consumption data. The study found that seafood lovers could ingest thousands of microplastic particles per year through regular consumption, with shellfish representing the highest per-serving exposure.
Occurrence and pathways of microplastics, quantification protocol and adverseeffects of microplastics towards freshwater and seawater biota
AI summary Read the abstract
This review examines the occurrence, pathways, and adverse effects of microplastics on freshwater and marine organisms, highlighting how these particles can enter the food chain through seafood consumption. The study suggests that microplastic ingestion causes health hazards in aquatic animals and points to gaps in understanding how microplastics affect human health along the food supply chain.
Impact of Microplastics on Aquatic Organisms and Human Health: A Review
AI summary Read the abstract
This review examined the impacts of microplastics on aquatic organisms and human health, highlighting that microplastic size ranges mimic prey sizes ingested by aquatic organisms and that contaminated commercially important fish species transfer microplastics to human consumers. The authors synthesised evidence on ingestion pathways, toxicological effects, and human dietary exposure routes.
Microplastics ingestion by marine fauna with a particular focus on commercial species: a systematic review
AI summary Read the abstract
This systematic review and meta-analysis examines microplastic ingestion across marine species, with a focus on commercially important seafood. The researchers found that microplastic contamination is widespread in fish, shellfish, and other marine animals that end up on our dinner plates. This matters for human health because we may be consuming these particles every time we eat seafood.
