Microplastic Occurrences in Sediments Collected from Marmara Sea-Istanbul, Turkey
AI summary Read the abstract
Researchers surveyed sediments in the Marmara Sea near Istanbul and found widespread microplastic contamination, with fibers being the most common type. The study adds to growing evidence of microplastic pollution in Turkish waters and highlights the Marmara Sea as a regional hotspot given its geography and population density.
Microplastics are persistent, synthetic polymers that have managed to spread even to the most remote places on earth. Studies reporting on the abundance of microplastics have recently increased worldwide, which has raised environmental concerns among scientific communities. Nevertheless, evidence of microplastic contamination from Turkey is limited even though the location is a critical point and the population is higher than most countries in the region. Thus, we aimed to detect microplastics in sediment samples collected from the Marmara Sea in Istanbul-Turkey. In this study, fourteen sediment samples were collected and sub-sampled, then plastic debris was extracted, quantified and characterized by the morphology and polymer structure. The result revealed that all of the samples contained microplastics, and their concentrations ranged between 0.3 and 85.6 g/kg sediment, and the most abundant plastic types were acrylonitrile butadiene styrene, ethylene vinyl acetate, and polystyrene.

Microplastics pollution in Gulf of Bandırma, Sea of Marmara: Biota and sediment
AI summary Read the abstract
Researchers assessed microplastic contamination in fish, mollusks, and sediment from the Sea of Marmara in Turkey. They found microplastics in all species examined, averaging about 2 to 3 particles per individual, with fibers and polyethylene terephthalate being the most common types. The results indicate widespread microplastic pollution throughout this marine environment that may accumulate through the food web.

Researchers conducted the first comprehensive survey of microplastic pollution in shoreline sediments across the entire Sea of Marmara and Canakkale Strait in Turkey. The study found microplastic abundances ranging from 199 to 1,286 items per kilogram, dominated by fibers and fragments, with polyethylene as the most common polymer type and blue as the most prevalent color.

Concentration and Characterisation with Spectroscopic Technique of Microplastics in the Surface Sediment and Commercial Fish Species of Gemlik Bay (Marmara Sea)
AI summary Read the abstract
Researchers surveyed microplastic contamination in sediment and commercial fish in Gemlik Bay in the Marmara Sea, Turkey, finding widespread contamination with fibres as the dominant type and higher concentrations near the harbour. Because several of the fish species sampled are commonly eaten, the results point to a direct route of microplastic exposure for people consuming seafood from this region.
