ClearMicroplastic pollution profile and potential ecological risk of in Aksu Stream (Giresun, Türkiye)
Researchers surveyed microplastic contamination in water and sediment samples from Aksu Stream in Turkey, which serves as a drinking water source. They found 910 microplastic items per kilogram in sediment and 0.65 items per liter in water, with transparent fragments and fibers being the most common. The study indicates that even streams used for drinking water supply are not free from microplastic pollution.

This study characterized microplastic pollution in sediment and seawater samples from six stations along the Black Sea coast of Giresun province, Turkey. Using microscopy and µ-FTIR spectroscopy, researchers identified widespread MP contamination with fibers and fragments as the dominant particle types.
Microplastics in the Euphrates: Assessing contamination in water, sediment, and commercial fish species
Researchers conducted the first integrated assessment of microplastic contamination in water, sediment, and six fish species across 23 sites in the Euphrates River, Turkey. MPs were detected in 52.2% of water samples and 43.5% of sediment samples, with fibers and PET dominant; fish species with benthic feeding behavior had higher microplastic loads.
Microplastics in freshwater environment: the first evaluation in sediments from seven water streams surrounding the lagoon of Bizerte (Northern Tunisia)
Researchers conducted the first assessment of microplastic contamination in surface sediments from seven streams surrounding the lagoon of Bizerte in northern Tunisia, finding microplastics at all sites with abundances up to 6,920 items per kilogram dry weight and fibers as the dominant particle type.

Researchers assessed microplastic abundance in both water and sediment of the Joumine stream in northern Tunisia, finding average concentrations of 8.87 particles/L in water and 18.2 particles per 50g dry weight in sediment, dominated by fibers and polypropylene and polyethylene polymers.
Investigation of microplastic pollution in Torghabeh River sediments, northeast of Iran
Researchers investigated microplastic pollution in sediments of the Torghabeh River in northeast Iran. The study found an average concentration of 8 particles per 100 grams of dry sediment, with polystyrene being the most abundant polymer, and areas with greater human activity showing higher levels of microplastic contamination.
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 in stream sediments discharging from Türkiye's eastern Black sea basin
Researchers characterized microplastic pollution in stream sediments from rivers discharging into the southeastern Black Sea from Turkey. The study found microplastics across 59 sampling sites, with varying composition and abundance, confirming that rivers serve as a principal transport route for terrestrial microplastics into this semi-enclosed sea.
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.
