Sources and sinks of microplastics in Canadian Lake Ontario nearshore, tributary and beach sediments
Researchers surveyed microplastic contamination in Lake Ontario sediments from nearshore areas, tributaries, and beaches to map pollution patterns. They found the highest concentrations near urban and industrial zones, particularly in Toronto Harbour, where levels exceeded 500 particles per kilogram of sediment. The study identifies wastewater outflows and urban runoff as key sources of microplastic pollution in the Great Lakes region.
Global microplastic contamination in freshwater lakes: Spatial patterns, environmental drivers, and methodological challenges
This review systematically analyzed 84 studies covering more than 300 lakes worldwide to assess global microplastic contamination in freshwater lake systems. Surface water MP concentrations ranged from below 0.001 to over 200 MP/L, with fibers and fragments dominating, polyethylene and polypropylene most common, and highest levels found in shallow, lowland, and eutrophic systems near urbanized shorelines.
Research status and prospects of microplastic pollution in lakes
This review systematically covers microplastic pollution research in lakes, including sampling and identification methods, distribution patterns, ecological effects, and knowledge gaps, identifying lakes as important but understudied sinks for microplastic contamination.
Microplastics in lakes and rivers: an issue of emerging significance to limnology
Researchers found that microplastic concentrations in freshwater lakes and rivers can exceed those of living organisms like zooplankton, with sediment levels matching the most contaminated marine sites, establishing microplastics as a significant issue for limnology.
Source-specific categorization of microplastics in nearshore surface waters of the Great Lakes
A source-specific characterization study of microplastics in nearshore surface waters of the Great Lakes found the highest abundances near urban centers, with distinct polymer and color signatures linking particles to packaging, fibers, and industrial sources.
Microplastic distribution in large shallow lake sediments: Variations with offshore distance and implications for microbial communities
Researchers analyzed microplastic distribution in sediments of Taihu Lake at varying distances from shore and examined the effects on microbial communities. They found that microplastic abundance decreased with increasing distance from the shoreline, ranging from 240 to 1,120 items per kilogram. The study suggests that microplastic contamination in lake sediments can significantly alter the composition and diversity of local microbial communities.

Review of microplastics in lakes: sources, distribution characteristics, and environmental effects
This review analyzes microplastic pollution in lakes worldwide and finds that contamination levels are higher in shallower lakes near populated areas with more human activity. Microplastics accumulate heavily in lake sediments and can also be trapped in seasonal ice, only to be released during warming periods. Since many communities rely on lakes for drinking water and fishing, understanding how microplastics concentrate in these freshwater systems is critical for protecting public health.

Researchers found microplastic abundances in Lake Huron sediments ranging from 59 to 335,714 particles per kg dry weight, with the North Channel showing the highest concentrations averaging 47,398 particles per kg. Results indicated that hydrodynamic processes such as waves and currents drive offshore distribution more than proximity to pollution sources.
Microplastics in 132 Iowa lakes and variability in relation to abiotic, biotic, and anthropogenic factors
Researchers surveyed microplastic concentrations across 132 lakes in Iowa, finding that microplastics were nearly ubiquitous even in rural, minimally developed lakes — though concentrations were higher in lakes near urban areas, agricultural land, and higher human population density. Fiber-type microplastics were most common, consistent with patterns seen globally. The broad survey across diverse lake types provides compelling evidence that microplastic contamination of freshwater lakes is widespread across the American Midwest, not limited to industrial or highly urbanized regions.
