Microplastics (MP), the debris that collectively refers to plastic fragments and particles of <5 mm in size within marine environments, has been the subject of interest within the past decade. Evidence of its occurrence and abundance, has been recorded in this communication after examining gastrointestinal specimens of eight commercially available fish species common to the Arabian (Persian) Gulf acquired locally from the State of Kuwait. The species studied belonged to different trophic levels, and the specimens were subjected to Micro Raman and Micro Fourier Infrared Spectroscopy (FTIR) in Attenuated Reflective Mode (ATR) to determine the presence and type of polymer of the MP. The detected MP set a president for the first time in the examined fish species within the State of Kuwait, which are of immense commercial importance. Various particles were detected, and three MP particles (fragments) were detected within the guts of Acanthopagrus latus, Eleutheronemaa tetradactylum and Lutjanus quinquelineatus. Based on the nature and behaviour of these particular fish types which prefer to stay in muddy waters and sheltered lagoons, it is suspected that common primary sources of MP (i.e. waste fragmentation) have led to passive/active intake (e.g. detritus ingestion) of these particles (fragments) by these species of fish in Kuwait.
微塑料（MP）是指在海洋环境中尺寸小于 5 毫米的塑料碎片和颗粒的总称，在过去十年中一直是研究的热点。在对从科威特国当地获得的 8 种商业上常见的、在阿拉伯（波斯）湾捕获的鱼类的胃肠道样本进行检查后，本研究记录了其存在和丰度的证据。所研究的物种属于不同的营养级，并用微拉曼和微傅里叶变换红外光谱（FTIR）在衰减全反射模式（ATR）下对样本进行了检测，以确定 MP 的聚合物的存在和类型。在所检查的科威特鱼类物种中，首次检测到的微塑料为这些具有巨大商业重要性的鱼类树立了一个先例。检测到了各种颗粒，并且在 Acanthopagrus latus、Eleutheronema tetradactylum 和 Lutjanus quinquelineatus 的肠道中检测到了 3 个微塑料颗粒（碎片）。根据这些类型的鱼更喜欢在泥泞水域和受保护的泻湖中停留的性质和行为，可以怀疑微塑料的常见的主要来源（即废物碎片）导致了这些科威特鱼类物种被动/主动摄入（例如，碎屑摄入）这些颗粒（碎片）。
