ClearMicroplastics in lakes: Distribution patterns and influencing factors
This review analyzed 84 studies across 64 lakes worldwide to understand where microplastics tend to concentrate in freshwater systems. Microplastic levels were highest near areas of heavy human activity and water inflows, and concentrations in lake sediments have been increasing over time, which matters because lakes are important sources of drinking water.
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.
Microplastic pollution of worldwide lakes
This review compiles research on microplastic pollution across 98 lakes worldwide, finding contamination in every lake studied. Lakes act as temporary or long-term accumulators of microplastics because water can remain in them for extended periods, and they receive plastic waste from surrounding areas. The review highlights that freshwater microplastic contamination deserves as much attention as ocean pollution, especially since many communities depend on lakes for drinking water and food.

This book chapter reviews microplastic pollution in urban lake surface waters and sediments, describing sources, distribution patterns, and the ecological consequences of MP accumulation in these widely used but understudied freshwater habitats.
Monitoring of microplastic concentrations in 132 Iowa lakes in relation to abiotic, biotic, and anthropogenic factors
Researchers surveyed microplastic concentrations in 132 lakes across Iowa, examining how biological, physical, and human factors influence plastic levels. Lakes near populated areas and with greater human activity showed higher microplastic concentrations, demonstrating that freshwater lakes are broadly contaminated by plastic pollution.
Global occurrence characteristics, drivers, and environmental risk assessment of microplastics in lakes: A meta-analysis
This meta-analysis of 42 studies found significant heterogeneity in microplastic pollution levels across global lakes, driven by geographical location and sampling methods. Small microplastics (under 1 mm) were disproportionately concentrated in sediment compared to water, and while most lakes showed low overall environmental risk, pollution levels in lake sediments were generally higher than in surrounding water.
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.
Lake sediments as microplastic sink: The case of three lakes from Northern and Central Poland
Researchers measured microplastic concentrations in bottom sediments from three lakes in northern and central Poland with low surrounding human activity, finding between 4 and 21 microplastic particles per kilogram of wet sediment. These values were low compared to lakes in urbanized areas, suggesting anthropogenic pressure significantly drives sediment microplastic accumulation.
A comparative review of microplastics in lake systems from different countries and regions
Researchers reviewed microplastic contamination data from lake systems across multiple countries, finding that abundance, size, and polymer type varied widely by region and identifying land use, population density, and hydrological connectivity as key drivers of lake microplastic levels.
Microplastics: Not a Micro Issue
This article presents an overview of microplastic pollution in oceans and lakes, reviewing sources, distribution, ecological impacts, and current research priorities. It emphasizes that microplastic contamination is no longer a minor issue but a serious threat to aquatic ecosystems and potentially to human health.
Hotspots lurking underwater: Insights into the contamination characteristics, environmental fates and impacts on biogeochemical cycling of microplastics in freshwater sediments
This review examines how microplastics accumulate in freshwater lake and river sediments, which act as major collection points for these particles. Researchers found that microplastic distribution in sediments varies significantly depending on local conditions, and that the particles can alter nutrient cycling and affect sediment-dwelling organisms. The study highlights freshwater sediments as critical but understudied hotspots for microplastic contamination.
Distribution Characteristics and Impact of Microplastics: A Literature Review
This literature review summarizes the types, sources, distribution, and pollution status of microplastics in marine and lake environments, their interactions with other contaminants, and removal technologies. It finds MPs are prevalent across aquatic environments and harmful to biological and human health, with some effective removal technologies available but implementation remaining limited.

Microplastics Are Contaminants of Emerging Concern in Freshwater Environments: An Overview
This overview examines the emerging problem of microplastic contamination in freshwater environments, covering sources, occurrence, and potential effects on aquatic ecosystems. The authors discuss how microplastics enter lakes and rivers through wastewater treatment plants, runoff, and degradation of larger plastic debris. The review highlights that freshwater microplastic pollution deserves the same research attention as marine contamination, given that rivers serve as major transport pathways for plastics reaching the ocean.
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.
