ClearThe effect of tourism on microplastic pollution amount in Baltic Sea Region lakes
Researchers measured microplastic pollution in surface water and sediments from 10 lakes in Latvia, Lithuania, and Poland across spring, summer, and autumn 2023, finding that tourism pressure in lake catchment areas correlates with elevated microplastic contamination levels.
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.
Sources Affecting Microplastic Contamination in Mountain Lakes in Tatra National Park
Analysis of 11 Tatra National Park mountain lakes found that global atmospheric transport was the dominant microplastic source rather than local tourism activity, with lake morphometry and elevation influencing contamination levels in these UNESCO-protected alpine ecosystems.
Litter per liter – Lakes' morphology and shoreline urbanization index as factors of microplastic pollution: Study of 30 lakes in NE Poland
Researchers surveyed microplastic contamination across 30 lakes in northeastern Poland during summer stagnation, examining how lake morphology and shoreline urbanization influence pollution levels. The study found microplastics in every lake sampled, with concentrations ranging from 0.27 to 1.57 particles per liter, and observed gradual accumulation patterns linked to human activity and lake characteristics.
Review of microplastics in lakes: sources, distribution characteristics, and environmental effects
This review analyzes microplastic pollution in lakes worldwide and finds that contamination levels are higher in shallower lakes near populated areas with more human activity. Microplastics accumulate heavily in lake sediments and can also be trapped in seasonal ice, only to be released during warming periods. Since many communities rely on lakes for drinking water and fishing, understanding how microplastics concentrate in these freshwater systems is critical for protecting public health.
Assessing the Occurrence and Distribution of Microplastics in Surface Freshwater and Wastewaters of Latvia and Lithuania
Researchers measured microplastic concentrations in surface water and wastewater across four Baltic cities in Latvia and Lithuania, finding an average of 16.63 particles/L with fibers as the dominant shape and polyethylene terephthalate as the most common polymer, with municipal and hospital wastewater identified as the primary contamination sources.
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.
Microplastic pollution of the Vistula Lagoon and Baltic Sea: A comparison study
Researchers compared microplastic levels in the Vistula Lagoon and the nearby Baltic Sea, finding higher concentrations in the more enclosed lagoon where particles accumulate rather than dispersing. Fibers were the dominant type in both locations, with notably longer fibers trapped in the lagoon, establishing a first baseline for plastic pollution in this understudied region.
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.
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.
Linking the Tourism Activity to the Occurrence and Distribution of Microplastics
Researchers assessed microplastic abundance, type, and spatial distribution in coastal water, sediments, and fish across three zones of Gili Trawangan, Indonesia, finding that tourism-related activities concentrated microplastics at recreational beaches with concentrations reaching 19.25 particles/L.
Microplastics in coastal sediments of Ełckie Lake (Poland)
Scientists sampled sediments around a Polish lake and found microplastics across all areas, with the highest concentrations near urban and tourist zones. Lake sediments are increasingly recognized as microplastic sinks, accumulating plastic that enters from surrounding land use activities.
Microplastics 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.
Why sampling season and location matter for monitoring micro and mesoplastics on the beach
Researchers analyzed microplastic pollution across 11 marine beaches in Latvia over four seasons from autumn 2022 to summer 2023, demonstrating how sampling season and location significantly influence measured pollution levels in the Baltic Sea region due to seasonal weather patterns and local hydrodynamics.
Tracing microplastic pathways: assessing pollution in a freshwater lake with high tourist activity
Lake Gölcük in western Turkey, a freshwater lake under growing pressure from tourism and development, was found to contain microplastics across all sampled compartments—water, sediments, fish muscle, fish digestive tracts, and invertebrate tissues. Tourist-heavy areas of the lake showed the highest contamination, suggesting recreational human activity is a major local source. The presence of microplastics in fish muscle tissue is particularly significant because it indicates that plastic particles can enter the human food chain through locally caught fish.
Microplastic contamination of sandy beaches of national parks, protected and recreational areas in southern parts of the Baltic Sea
Researchers found microplastic contamination in all 51 surface beach sand samples across seven sites along the southern Baltic Sea, including national park and protected areas, at a mean of 68 items/kg dry weight. Expanded polystyrene fragments were the most common type (~38%), and protected areas did not differ substantially from recreational beaches.
Plastic contamination of sandy beaches along the southern Baltic – a one season field survey results
Researchers surveyed microplastic and macroplastic contamination along the Polish Baltic Sea coast, finding microplastic concentrations of 118–1,382 pieces/kg in beach sand and 0.61–2.76 pieces/dm3 in coastal waters, with sub-1 mm blue fibers dominating across all sites and suggesting a common fibrous source throughout the Polish coastal zone.

Micro- and Mesoplastic Monitoring on Beaches: Understanding Seasonal and Spatial Distribution Patterns
Researchers monitored microplastic abundance and composition across 11 Latvian Baltic Sea beaches over four seasons from autumn 2022 to summer 2023, finding that seasonal climate patterns and proximity to the Gulf of Riga influence both microplastic load and spatial distribution along the northeastern European coastline.
Variability of microplastic loading and retention in four inland lakes in Minnesota, USA
Researchers measured microplastic levels in four small lakes in Minnesota and found that watershed size and urban development were the biggest factors driving contamination. Surface water concentrations varied widely, and sediment levels did not directly correlate with what was found in the water above. The study highlights how local land use patterns influence where microplastics end up in freshwater ecosystems.
