ClearMicroplastics in freshwater systems: Dynamic behaviour and transport processes
This review examines how microplastics move through freshwater systems like rivers and lakes on their way to the ocean. The behavior of these particles, including whether they sink, float, or clump together, depends on their size, shape, and density, which constantly change as the plastics weather and interact with organisms. Understanding these transport processes is critical because freshwater systems are a major pathway for microplastic pollution that eventually affects drinking water and aquatic food sources.
Microplastic contamination, an emerging threat to the freshwater environment: a systematic review
Researchers systematically reviewed the spread of microplastics in freshwater ecosystems — rivers, lakes, and streams — documenting their sources, how they move through water, the damage they cause to aquatic organisms, and the methods used to detect them. Their review serves as a baseline reference for future research and calls for improved waste management to protect freshwater environments from ongoing microplastic contamination.
The Complex Dynamics of Microplastic Migration through Different Aquatic Environments: Subsidies for a Better Understanding of Its Environmental Dispersion
This review explores how microplastics move through different aquatic environments, from rivers and lakes to estuaries and oceans, focusing on the physical properties that drive their transport. Researchers found that factors like particle density, size, shape, and biofouling all influence where microplastics accumulate and how far they travel. Understanding these migration dynamics is essential for predicting contamination patterns and designing effective cleanup strategies.
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.
A Review of the Migration and Transformation of Microplastics in Inland Water Systems
This review examined how microplastics migrate and transform in rivers, lakes, and reservoirs, tracing their journey from manufacturing through disposal to aquatic environments. The study suggests that microplastics undergo multiple fate stages in inland waters, including suspension, deposition, resuspension, burial, and ingestion by organisms, eventually reaching the marine environment.
Microplastics in Aquatic Ecosystems: A Critical Review of Sources, Transport Mechanisms and Ecotoxicological Risks
This review provides a broad overview of microplastic pollution in rivers, oceans, and other aquatic environments, covering where these particles come from, how they move through water systems, and the harm they can cause. Evidence indicates that microplastics accumulate toxins and disrupt growth, feeding, and reproduction in aquatic species, with potential consequences for human health through seafood and drinking water. The authors stress the need for better global monitoring, stronger waste management systems, and development of eco-friendly plastic alternatives.
Comprehensive review of the co-transport of microplastics and suspended sediments in aquatic environments: macroscopic transport and microscopic mechanisms
Researchers reviewed how microplastics and suspended sediments interact and travel together through rivers, lakes, and coastal waters, identifying water flow conditions, particle density, and plastic shape as key factors governing their joint migration and deposition. Understanding these co-transport dynamics is essential for predicting where microplastics accumulate and assessing their ecological risks.
Plastic and Microplastic in the Environment
This review summarizes the sources, pathways, analytical methods, and distribution of microplastics in freshwater environments, emphasizing that rivers and lakes are major conduits transferring plastic pollution from terrestrial sources to the oceans.
Riverine microplastics and their interaction with freshwater fish
This paper reviews how microplastics enter river systems, how they move through waterways, and the risks they pose to freshwater fish. Researchers found that fish ingest microplastics that can accumulate in organs and carry toxic chemicals absorbed from the water. The review highlights that river fish, an important food source for many communities, face growing exposure to microplastics from urban runoff, wastewater, and agricultural sources.
Micro-plastics in Aquatic Environment: Source, Fate, Emerging Threats, and Regulatory Effort
This review covers sources, distribution, and threats of microplastics in aquatic environments, tracing their movement through rivers, estuaries, lakes, and oceans and their accumulation in sediments and the food chain.

This review summarizes how microplastics enter freshwater ecosystems from sources like industrial runoff, urban waste, and agriculture, and how they accumulate in sediments where aquatic organisms ingest them. Researchers found that microplastics reduce feeding efficiency, inhibit growth, and harm reproduction in freshwater species, while also acting as carriers for toxic chemicals that build up through the food chain.
