ClearOccurrence and Quantification of Natural and Microplastic Items in Urban Streams: The Case of Mugnone Creek (Florence, Italy)
Researchers monitored microplastic and natural fiber fluxes in Mugnone Creek, a small urban stream in Florence, Italy, over two years across dry and wet seasons, finding the creek transports significant microplastic loads to the Arno River and ultimately the Tyrrhenian Sea.
Microplastics and their possible sources: The example of Ofanto river in southeast Italy
Microplastics were surveyed in the Ofanto River in southeast Italy—the first such study in this region—characterizing abundance and composition in banks, surface waters, and sediments and identifying multiple potential input sources including agricultural runoff and urban waste. The study demonstrates that this major Italian river is contaminated with microplastics and transports them toward the Adriatic Sea.
Multidisciplinary analysis of microplastic dynamics: from sources to environmental fate in urban rivers during floods
Researchers conducted a multidisciplinary investigation of microplastic dynamics in urban rivers, combining flume experiments on riparian vegetation, polymer-specific quantification using PLE-Py-GC/MS, and a catchment-scale connectivity model to map land-to-river microplastic transport within the Arno basin.
The role of urban streams in the microplastics contamination scenario: the case study of the Mugnone Creek (Florence, Italy)
Researchers examined microplastic contamination in sediments and waters of the Mugnone Creek, a minor urban stream flowing through Florence, Italy, as a case study for understanding how urban streams contribute to microplastic transport from cities to the sea. The study measured microplastic concentrations across the stream's urban catchment and assessed the role of impervious surface runoff in delivering microplastics to the creek and ultimately to the Arno River.
Mechanisms of microplastics trapping in river sediments: Insights from the Arno river (Tuscany, Italy)
Researchers analyzed microplastic trapping mechanisms in Arno River sediments in Italy, distinguishing between particles associated with floating plant debris and those trapped in clastic sediment, revealing how rivers temporarily store microplastics during transport to the sea.
Microplastics distribution in marine sediments offshore the Tiber River mouth (Central Tyrrhenian Sea): the role of sedimentary processes
Researchers investigated the distribution of microplastics in fluvial and marine sediments along the lower Tiber River and the Central Tyrrhenian Sea, examining how sedimentary processes control land-to-sea transfer and spatial dispersal of microplastics originating from the city of Rome.
Knowledge about Microplastic in Mediterranean Tributary River Ecosystems: Lack of Data and Research Needs on Such a Crucial Marine Pollution Source
This review surveys the limited literature on microplastic pollution in freshwater rivers feeding the Mediterranean Sea, finding major gaps in data and inconsistent methods. The authors call for standardized monitoring protocols to better understand how rivers transport microplastics from land to the ocean.
Spatio-temporal distribution of microplastics in a Mediterranean river catchment: The importance of wastewater as an environmental pathway
Microplastic concentrations were mapped across a Mediterranean river catchment in central Spain over multiple seasons, finding that wastewater treatment plant effluents were the dominant point source and that storm events transiently increased concentrations in downstream reaches by mobilizing accumulated particles from river beds and floodplains.
Pollution by anthropogenic microfibers in North-West Mediterranean Sea and efficiency of microfiber removal by a wastewater treatment plant
Researchers systematically measured synthetic microfiber pollution across multiple environmental compartments in an urban area of northwest France, including air, washing machine effluent, wastewater treatment plant (WWTP) inlet/outlet, and Mediterranean coastal and offshore waters. They found that clothing laundering was a major microfiber source, and while the WWTP removed a substantial proportion of fibers, significant quantities still entered coastal waters.
The contamination of inland waters by microplastic fibres under different anthropogenic pressure: Preliminary study in Central Europe (Poland)
This Polish study measured microfiber contamination in a river and three lakes across central and northeastern Poland, finding significantly higher fiber counts in the river flowing through large cities than in lakes within a protected landscape park. Urban rivers carry substantially higher microplastic fiber loads than relatively undisturbed freshwater bodies, confirming that human activity drives contamination levels.
Microplastics distribution in marine sediments offshore the Tiber River mouth (Central Tyrrhenian Sea): the role of sedimentary processes
Researchers investigated microplastic distribution in Tiber River sediments and offshore marine sediments from 10 to 100 meters depth near Rome, finding that river discharge and sedimentary processes strongly influence the land-to-sea transfer and spatial dispersal of microplastic particles in the central Tyrrhenian Sea.
Microplastic pollution in rivers of the Adriatic Sea basin in Montenegro: Impact on pollution of the Montenegrin coastline
Researchers measured microplastic concentrations in sediments along three Montenegrin river shores draining into the Adriatic Sea, finding an average of 164 MPs/kg dominated by polyethylene and polypropylene fibers and fragments, identifying these rivers as both sinks and potential sources of coastal microplastic pollution.
Synthetic and non-synthetic anthropogenic fibers in a river under the impact of Paris Megacity: Sampling methodological aspects and flux estimations.
This study sampled a French river downstream of Paris and measured both synthetic and natural processed fibers in the water, finding high concentrations of fibers with significant short-term variability. The research highlights that fiber pollution extends beyond conventional plastic particles to include a wide range of textile-derived materials that are often missed in standard monitoring.
Riverine microplastic contamination in southwest Germany: A large-scale survey
A large-scale survey of microplastic contamination across multiple rivers in southwest Germany found that contamination increased from headwaters to lowland sections and was elevated downstream of urban areas and wastewater treatment plant discharges. Fibers dominated in all rivers, and the study highlighted rivers as both pathways and temporary sinks for microplastics.
Riverine Microplastic Loading to Mersin Bay, Turkey on the North-eastern Mediterranean
Researchers characterized microplastics in eight rivers discharging into Mersin Bay in the northeastern Mediterranean, finding fibres dominated at 83.5% of particles and calculating a total load of approximately 1,200 billion particles delivered to the bay. Microplastic characteristics in the rivers closely matched those previously documented in the marine environment of Mersin Bay.
First evaluation of floating microplastics in the Northwestern Adriatic Sea
Floating microplastics were surveyed for the first time in the northwestern Adriatic Sea, finding that the Venice Lagoon and Po River are likely important sources. The findings help map microplastic inputs into this semi-enclosed sea and can inform targeted mitigation efforts.
