ClearComparative Distribution of Microplastics in Different Inland Aquatic Ecosystems
Researchers sampled seven Greek inland aquatic ecosystems of varying types and found microplastics in all locations, with fibers dominating (0.47–149.4 items/m³) and higher concentrations in vertical than surface samples, indicating that morphology, trophic status, and anthropogenic pressure influence distribution.
Microplastics Across Interconnected Aquatic Matrices: A Comparative Study of Marine, Riverine, and Wastewater Matrices in Northern Greece
Researchers studied tiny plastic particles (microplastics) in seawater, rivers, and wastewater treatment plants in Northern Greece to see how much plastic pollution exists in the region's water systems. They developed a reliable method to measure these microscopic plastic pieces, which can enter our food chain through seafood and drinking water. This baseline data will help authorities track plastic pollution levels and develop strategies to reduce microplastics in water that could eventually affect human health.
Microplastics Across Interconnected Aquatic Matrices: A Comparative Study of Marine, Riverine, and Wastewater Matrices in Northern Greece
Scientists studied tiny plastic particles (microplastics) in seawater, rivers, and wastewater treatment plants in Northern Greece to understand how much plastic pollution exists in the region's water systems. They developed a reliable method to measure these microscopic plastic pieces and established baseline pollution levels that can help authorities create better strategies to reduce plastic contamination. This matters because microplastics can enter our drinking water and food chain, and understanding where they're most concentrated helps protect both environmental and human health.

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.
Prevalence of Microplastic Pollution in Freshwater Ecosystem: A Case Study of Thal Canal
Researchers surveyed microplastic contamination in a freshwater ecosystem in a case study region, measuring particle concentrations and types in water and sediment samples across multiple sites. Microplastics were detected at all sampling locations with higher concentrations near urban areas, and fibres and fragments were the dominant particle morphologies found.
Characterization of microplastics in sediments and surface waters of Turkish lakes
Researchers surveyed seven lakes in Turkey and found microplastics in all of them, with polyethylene and polypropylene being the most common types. Human activities like tourism, fishing, and urban waste disposal were identified as major sources, showing that even protected lake areas are contaminated with plastic particles that can enter drinking water supplies.
Effects of environmental and anthropogenic factors on the distribution and abundance of microplastics in freshwater ecosystems
Researchers reviewed nearly 6,500 articles to identify the environmental and human factors driving microplastic distribution in freshwater ecosystems worldwide. They found that both natural factors like water flow and temperature, and human activities like urbanization and agriculture, significantly influence where microplastics accumulate in rivers and lakes. The study provides a framework for predicting microplastic pollution hotspots and prioritizing monitoring efforts in freshwater systems.
