Microplastics and Anthropogenic Particles in Recreationally Caught Freshwater Fish from an Urbanized Region of the North American Great Lakes
AI summary Read the abstract
Researchers found microplastics in recreationally caught freshwater fish from the Great Lakes region near Toronto, with higher particle counts in fish from urbanized Humber Bay. The study confirms that eating freshwater fish is a pathway for human microplastic exposure. While the health effects of ingesting these particles are still unclear, the findings support the need for broader geographic monitoring and inclusion in human health risk assessments.
Our findings suggest that consumption of recreationally caught freshwater fish can be a pathway for human exposure to microplastics. The elevated number of particles observed in fish from Humber Bay highlights the need for large-scale geographic monitoring, especially near sources of microplastics. Currently, it is unclear what the effects of ingesting microplastics are for humans, but given that recreationally caught freshwater fish are one pathway for human exposure, these data can be incorporated into future human health risk assessment frameworks for microplastics. https://doi.org/10.1289/EHP13540.

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.
Microplastic particles observed in multiple tissues of lake ontario sportfish
AI summary Read the abstract
Researchers quantified microplastics in both gastrointestinal tracts and fillets of six sportfish species from Humber Bay, Lake Ontario, finding anthropogenic particles in all fish sampled with a mean of 147.9 particles per individual and up to 1,508 in a single fish, and observing that gut particle counts did not predict fillet particle counts, suggesting independent translocation pathways.
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.
Factors influencing the variation of microplastic uptake in demersal fishes from the upper Thames River Ontario
AI summary Read the abstract
Researchers examined microplastic uptake in white sucker and common carp at 11 sites along the Thames River in Ontario and found that proximity to urban areas and wastewater treatment plant outflows was the strongest predictor of microplastic abundance in fish tissues.
