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.
微塑料是持久性的合成聚合物，甚至已经扩散到地球上最偏远的地方。最近，全世界关于微塑料丰度的研究报告有所增加，这引起了科学界的环境担忧。然而，即使土耳其是一个关键地点，其人口也高于该地区的大多数国家，但来自土耳其的微塑料污染证据仍然有限。因此，我们旨在检测来自土耳其伊斯坦布尔马尔马拉海的沉积物样本中的微塑料。在这项研究中，采集了 14 个沉积物样本并进行了亚采样，然后通过形态和聚合物结构提取、量化和表征塑料碎片。结果表明，所有样本都含有微塑料，其浓度范围在 0.3 到 85.6 克/千克沉积物之间，最丰富的塑料类型是丙烯腈-丁二烯-苯乙烯、乙烯-醋酸乙烯酯和聚苯乙烯。
