The Turkish Straits System (TSS) is a dangerous and narrow waterway extending between the Black Sea and the Aegean Sea, including the Bosphorus, the Dardanelles, and the Marmara Sea and the Gulf of Izmit. The western banks of the TSS constitute the geographic starting point of the European continent, while the banks to the east are the beginnings of the Asia. TSS is considered one of the most strategically significant waterways of the world. This waterway is the main trading routes linking the Black Sea riparian countries to the world markets. As a result, the density in marine traffic through the TSS has recently reached alarmingly high levels. The aim of this study was to estimate the amount of plastic waste generated aboard merchant ships during their passage through the TSS during the period 2006–2017. This potential resource of waste would potentially impact on the Marmara Sea and its natural environment. The results of this study revealed that merchant ships crossing the TSS generated an average of 187.6 m³ of plastic waste per year. This result suggests that the threat given by the ships crossing this strait is approximately 1% of the total amount of waste recorded in the TSS coastals.

土耳其海峡系统（TSS）是一条危险的狭窄水道，在黑海和爱琴海之间延伸，包括博斯普鲁斯海峡，达达尼尔海峡，马尔马拉海和伊兹密特海湾。TSS的西部银行构成了欧洲大陆的地理起点，而东部的银行则是亚洲的起点。TSS被认为是世界上最具战略意义的水道之一。这条水路是连接黑海沿岸国家与世界市场的主要贸易路线。结果，通过TSS的海上交通密度最近达到了惊人的高水平。这项研究的目的是估计2006-2017年期间商船通过TSS时产生的塑料废物量。这种潜在的浪费资源可能对马尔马拉海及其自然环境产生影响。这项研究的结果表明，穿越TSS的商船平均产生了187.6 m每年³个塑料废料。该结果表明，越过该海峡的船只所造成的威胁大约是TSS沿海地区记录的废物总量的1％。
