Occurrence, Sources, Transport, and Fate of Microplastics in the Great Lakes–St. Lawrence River Basin
AI summary Read the abstract
Researchers documented that microplastics smaller than five millimeters are present throughout the Great Lakes and St. Lawrence River system, from tributary streams to the Atlantic Ocean. This finding suggests that the Great Lakes region is both a major accumulation zone and a transport pathway for microplastic pollution into the broader marine environment.
Microplastics, plastic particles less than five millimeters in size, are found in each of the five Laurentian Great Lakes, their tributary streams and rivers, and the St. Lawrence River carrying Great Lakes water to the Atlantic Ocean. Although standardized...

Occurrence, Distribution, and Removal of Microplastics from Aquatic Ecosystems
AI summary Read the abstract
Researchers investigated the occurrence, distribution, and removal strategies for microplastics in aquatic ecosystems, reviewing how their pervasive presence and resistance to conventional treatment create persistent risks for both environmental and human health.
A Review on Microplastics Presence, Distribution, and Composition in Multiple Environmental Samples Across Canada
AI summary Read the abstract
This review synthesizes Canadian microplastic studies across water, wastewater, biosolids, and sediment, finding fibers and fragments most prevalent and polyethylene, PET, and polypropylene as dominant polymers across matrices. The Canadian-specific analysis highlights significant data gaps and the need for standardized national monitoring as plastic contamination increasingly reaches remote environments and enters the human food chain.
Occurrence and Fate of Microplastics in Freshwater Resources
AI summary Read the abstract
Microplastics enter freshwater resources through both primary sources such as cosmetic microbeads and secondary fragmentation of larger plastic debris, accumulating throughout river systems, lakes, and groundwater. Their persistence and widespread distribution in freshwater raise direct concerns for human exposure via drinking water consumption.
Microplastics in Water: Occurrence, Environmental Effects, and Removal Methods
AI summary Read the abstract
Researchers reviewed the sources, environmental effects, and removal methods for microplastics in water, finding these contaminants are widespread across drinking water, rivers, and oceans, and that current water treatment technologies are only partially effective at removing them before they reach people.
Fate and Behavior of Microplastics in Freshwater Systems
AI summary Read the abstract
Researchers reviewed how microplastics move, accumulate, and interact with ecosystems in freshwater environments like rivers and lakes, which serve as both major pathways and sinks for plastic pollution. Understanding this behavior is critical because freshwater sources supply drinking water for billions of people worldwide.
