Microplastic Retention by Type in Several Species of Fish from the Great Lakes
AI summary Read the abstract
This study examined microplastic retention by particle type in several species of fish from the Great Lakes, analyzing digestive tracts for plastic content across different fish feeding strategies. Fish from the Great Lakes are consumed by humans, making microplastic contamination in these species directly relevant to public health concerns.
Microplastics are plastic particles

Microplastic contamination in Great Lakes fish
AI summary Read the abstract
Researchers examined microplastic contamination in seven species of fish from Lake Ontario and Lake Superior, finding anthropogenic particles in the gastrointestinal tracts of fish from both lakes. The study documented higher concentrations in Lake Ontario, likely reflecting greater surrounding population density and urban input, and confirmed the particles were synthetic polymers through chemical analysis.
Variability in the drivers of microplastic consumption by fish across four lake ecosystems
AI summary Read the abstract
Researchers examined microplastic consumption by three fish species across four lakes in Minnesota and found that ingestion rates varied by species and feeding strategy. Filter-feeding fish consumed microplastics at rates that matched local water contamination levels, while visual feeders did not show the same pattern. The findings indicate that a fish's feeding behavior plays a major role in determining its microplastic exposure.
Occurrence of Microplastics in Digestive Tracts of Fish with Different Modes of Ingestion in Japanese Bays and Lake Biwa
AI summary Read the abstract
Researchers examined microplastics in the digestive tracts of seven fish species from five Japanese bays and Lake Biwa, finding particles in 37% of the 197 fish sampled. Filter-feeding fish had significantly higher microplastic ingestion rates than non-filter-feeders, suggesting that feeding mode is a key factor in microplastic exposure.
Effect of biological and environmental factors on microplastic ingestion of commercial fish species
AI summary Read the abstract
Researchers analyzed microplastic ingestion in commercially important fish species, evaluating how biological and environmental factors influence ingestion rates across 2,222 individual fish. The study assessed gastrointestinal tract contents to determine the extent and patterns of microplastic contamination. The findings suggest that both species-specific biology and environmental conditions play important roles in determining microplastic ingestion levels in commercial fish.
Microplastic in riverine fish is connected to species traits
AI summary Read the abstract
Researchers measured microplastic contamination in fish and surface waters from three Lake Michigan tributaries and found that a fish's feeding behavior — particularly bottom-feeding — was a stronger predictor of microplastic ingestion than the local water concentration. Round goby bottom-feeders had the highest microplastic loads, suggesting that food web position plays a key role in how microplastics accumulate in freshwater fish.
