Prevalence, Fate and Effects of Plastic in Freshwater Environments
This review summarizes the prevalence, environmental fate, and biological effects of plastics in freshwater ecosystems, an area that has received less attention than marine plastic pollution. Freshwater bodies are major pathways for microplastics to reach marine environments and are themselves affected by plastic contamination.
Microplastics in freshwater systems: A review of the emerging threats, identification of knowledge gaps and prioritisation of research needs
This review synthesizes the growing body of research on microplastic contamination in freshwater rivers, lakes, and sediments, which has received far less attention than marine environments. Researchers found that freshwater microplastic concentrations can rival or exceed those reported in ocean studies, particularly near urban and industrial areas. The study identifies critical knowledge gaps including the lack of standardized sampling methods and limited understanding of how microplastics affect freshwater organisms and ecosystems.
Beyond the ocean: contamination of freshwater ecosystems with (micro-)plastic particles
This review examined the available data on microplastic contamination in freshwater ecosystems — rivers, lakes, and urban water systems — and found it to be widespread globally, though often underreported compared to marine environments. The authors highlight the need for reliable concentration data and chemical characterization of freshwater plastics to properly assess ecological risk.
Assessment of microplastics in freshwater systems: A review
This review of microplastic research in freshwater systems found that while most pollution studies have focused on marine environments, freshwaters are major conduits and sinks for microplastics, with WWTPs being a key pathway rather than a complete barrier. The authors call for standardized methods and more research on freshwater microplastic sources, distribution, and effects.
Occurrence, Fate and Fluxes of Plastics and Microplastics in Terrestrial and Freshwater Ecosystems
This review examines the occurrence, transport pathways, and fate of plastics and microplastics in terrestrial and freshwater ecosystems globally, synthesizing evidence that these systems are both sources and sinks and that microplastics cycle between compartments in complex ways.
The organism fate of inland freshwater system under micro-/nano-plastic pollution: A review of past decade.
