Abstract

Microplastic (MP) pollution is an increasing concern in marine ecosystems due to the risk it poses to marine organisms and human health. This study aims to investigate the type, abundance, and properties of MPs in five commercially important fish species (Engraulis encrasicolus, Trachurus trachurus, Sardina pilchardus, Sarda sarda, and Dicentrarchus labrax) and Mediterranean mussels (Mytilus galloprovincialis). In the study, samples were collected from five different regions in the Southern Marmara Sea of Turkey. In addition, the polymer composition of MPs identified in the study was determined and evaluated according to the associated hazard index to determine the potential risks to marine life and human consumers. A total of 1734 MPs were identified in the gastrointestinal tracts (GITs) of fish samples (n = 660), while 650 MPs were identified in mussel samples (n = 50). The analyses revealed that there was significant interspecific and spatial variability in MP abundance, size, shape, and color. The most common MPs are those smaller than 0.3 mm in diameter. These are predominantly in the form of lines and beads in all species. Fourier transform infrared (FTIR) spectroscopy was used to identify the types of polymers present. The types of polymers identified in the study were polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), and ethylene vinyl acetate (EVA). The most common polymers were PE and PP, which showed hazard indices classified as “hazard” and “high risk,” respectively. The study identifies potential health risks associated with MPs, particularly in marine organisms, including apex predators such as D. labrax and filter feeders such as mussels. These findings highlight the need for effective waste management strategies, stricter regulations, and increased public awareness to reduce pollution of marine environments with plastic.

土耳其南马尔马拉海商业海洋鱼类和贻贝中微塑料污染的危害指数
由于微塑料污染给海洋生物和人类健康带来的风险,它在海洋生态系统中日益受到关注。本研究旨在调查五种重要商业鱼类(Engraulis encrasicolus、Trachurus Trachurus、Sardina pilchardus、Sarda Sarda和Dicentrarchus labrax)和地中海贻贝(Mytilus galloprovincialis)中MPs的类型、丰度和特性。在这项研究中,样本是从土耳其南马尔马拉海的五个不同地区收集的。此外,根据相关危害指数对研究中发现的MPs的聚合物组成进行了测定和评估,以确定其对海洋生物和人类消费者的潜在风险。在鱼类样本胃肠道(GITs)中共鉴定出1734种MPs (n = 660),在贻贝样本中共鉴定出650种MPs (n = 50)。分析表明,在MP丰度、大小、形状和颜色方面存在显著的种间和空间变异性。最常见的MPs是直径小于0.3毫米的MPs。在所有物种中,这些主要以线和珠的形式存在。傅里叶变换红外光谱(FTIR)用于识别存在的聚合物类型。研究中确定的聚合物类型有聚乙烯(PE)、聚丙烯(PP)、聚氯乙烯(PVC)、聚对苯二甲酸乙二醇酯(PET)和醋酸乙烯酯(EVA)。最常见的聚合物是PE和PP,其危害指数分别为“危险”和“高风险”。该研究确定了与MPs相关的潜在健康风险,特别是在海洋生物中,包括顶端捕食者,如D. labrax和滤食性动物,如贻贝。这些发现强调了有效的废物管理战略、更严格的法规和提高公众意识的必要性,以减少塑料对海洋环境的污染。

期刊介绍: International in perspective, Aquaculture Research is published 12 times a year and specifically addresses research and reference needs of all working and studying within the many varied areas of aquaculture. The Journal regularly publishes papers on applied or scientific research relevant to freshwater, brackish, and marine aquaculture. It covers all aquatic organisms, floristic and faunistic, related directly or indirectly to human consumption. The journal also includes review articles, short communications and technical papers. Young scientists are particularly encouraged to submit short communications based on their own research.
