ClearMicroplastics in karst ecosystems and its impact on drinking water quality
This doctoral dissertation investigated microplastic contamination in karst ecosystems — including springs, lakes, air, rainwater, and sediment — in Slovenia, with a focus on drinking water sources that serve over 20,000 residents. The research found microplastics present across all sampled environments and aimed to identify pollution sources and transport pathways to help protect vulnerable karst groundwater supplies.
Mikroplastika U Slatkim Vodama: Pregled Načina Uzorkovanja I Pratećih Analiza
This review summarizes methods for sampling and analyzing microplastics in freshwater environments, covering filtration, visual sorting, and spectroscopic identification techniques. Standardizing sampling methods is critical because microplastics are persistent pollutants that can take thousands of years to decompose and negatively affect aquatic organisms.
A Review of Microplastics in Freshwater Environments: Locations, Methods, and Pollution Loads
This review chapter summarizes global research on microplastics in freshwater environments, covering detection locations, sampling methods, and pollution levels. Because many freshwater bodies serve as drinking water sources, understanding where microplastics occur and in what quantities is critical for assessing risks to human health.
Microplastic in Freshwater Environment: A Review on Techniques and Abundance for Microplastic Detection in Lake Water
This review examines microplastic pollution in freshwater environments, summarizing detection techniques and reporting on abundance data from rivers, lakes, and streams worldwide. The authors highlight methodological inconsistencies that complicate cross-study comparisons and call for standardized sampling and analysis protocols.
Sources, Occurrence, and Analysis of Microplastics in Freshwater Environments
This review summarizes current knowledge on microplastic sources and occurrence in freshwater environments, noting that freshwater systems are major conduits delivering microplastics to the ocean. The review highlights that freshwater microplastic research lags far behind marine studies despite rivers and lakes being primary pollution pathways.
Microplastics in freshwater ecosystems : effects and drivers
This thesis assessed how microplastic exposure affects freshwater microorganisms, macroinvertebrates, and other organisms in freshwater ecosystems, finding that microplastics are a pervasive contaminant of freshwater environments with unclear but potentially significant ecological impacts.
Assessment of Different Sampling, Sample Preparation and Analysis Methods Addressing Microplastic Concentration and Transport in Medium and Large Rivers Based on Research in the Danube River Basin
Monitoring microplastics in rivers is hampered by the lack of standardized methods, making it difficult to compare results across studies. This research tested three common sampling approaches on the Danube River and its tributaries, finding that each method produced meaningfully different estimates of microplastic concentrations and transport. The results underscore the urgent need for agreed-upon protocols so that data from different countries and research groups can be reliably combined to track river-to-ocean plastic pollution.
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.
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.
Microplastic pollution in small rivers along rural–urban gradients: Variations across catchments and between water column and sediments
This study compared microplastic pollution in water column and sediments of two small Slovenian rivers with different levels of urbanization and wastewater treatment plant influence. Microplastic concentrations differed significantly between water samples from the two rivers but not in sediments, with fibers dominating in both matrices.
Plastic pollution in Swiss surface waters: nature and concentrations, interaction with pollutants
Researchers surveyed microplastic pollution in Swiss surface waters including multiple lakes and rivers. The study confirmed the presence of microplastics in Swiss freshwater environments and investigated interactions between microplastics and chemical pollutants, expanding the data on freshwater microplastic contamination beyond the initial findings from Lake Geneva.
Microplastics in Natural Water: Sources and Determination
This paper reviews the sources of microplastic pollution in aquatic environments and the analytical methods used to characterize and quantify microplastic particles, covering sampling, extraction, and identification techniques relevant to freshwater and marine monitoring.
The emerging issue of microplastics: ongoing investigation in water and sediments of subalpine lakes
This Italian study identified microplastics in subalpine lakes and characterized their polymer types and abundance, adding to evidence that microplastics have reached even remote freshwater ecosystems far from industrial centers. The findings underscore the ubiquity of plastic contamination across diverse freshwater environments.
The occurrence of microplastics in freshwater systems – preliminary results from Krakow (Poland)
This preliminary study measured microplastic concentrations in freshwater systems in Poland, finding particles widely distributed in both surface water and sediment. The research fills a gap in knowledge about microplastic contamination in Central European inland waterways.
Analysis, prevalence and impact of microplastics in freshwater and estuarine environments: an evidence review
This systematic review summarized the existing research on microplastics in freshwater rivers, lakes, and estuaries. It found that current microplastic levels in most freshwater environments are below the concentrations that cause lethal harm to aquatic life, but the highest-pollution sites may already pose risks for subtler health effects on fish and other organisms. The review also highlighted that different sampling methods produce very different results, making it hard to compare studies.
Microplastics pollution in groundwater: Case study - Slovenia
Researchers investigated microplastic pollution in Slovenian groundwater, which supplies drinking water to 98% of the population, characterizing MP occurrence, transport, and risk across multiple aquifer systems affected by urban, industrial, and agricultural activities.
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.
Detekce mikroplastů v životním prostředí
This Czech bachelor's thesis provides an overview of microplastics as environmental pollutants, covering their sources, detection methods, and potential health risks for humans and other organisms.

Microplastics in Polish Inland Waters: CurrentKnowledge, Methodological Limitations,and Research Needs
Researchers reviewed 33 studies on microplastic contamination in Polish rivers, lakes, and groundwater, finding concentrations ranging from 0 to 280 particles per liter in water and up to 120,000 particles per kilogram in sediments. The review highlights that inconsistent sampling and identification methods make it nearly impossible to compare results across studies, calling for standardized national monitoring.
