Abstract

Microplastics (μPs) represent an emerging problem for the marine environment given their wide bioavailability for all aquatic organisms, from zooplankton to top predators. This work aimed to evaluate a method of extracting microplastics from the gastrointestinal tract of 122 Sepia officinalis caught from the Adriatic Sea (along Abruzzo region coasts) to measure its quantity in a poorly investigated species. The extraction method used for gastrointestinal content was performed using 10% potassium hydroxide. In 98/122 (80.32-95% CI=73.27-87.37%) wild animals microplastics were detected with a mean concentration of 6.82±5.52 μPs/subject. Among the fragments, as supported by various authors, those of black color were the most represented ones; however, also blue fibers and transparent spheres were isolated. This study, in agreement with previous ones, poses further attention to the wide microplastic diffusion in the marine environment (surface, columns, sediments, and animals). The obtained results provide the basis for future investigations on this public health concern.

亚得里亚海中部海岸捕获的棕鲷体内的微塑料:初步结果。
微塑料(μPs)是海洋环境的一个新问题,因为它们对所有水生生物(从浮游动物到顶级捕食者)都具有广泛的生物利用度。本研究旨在评估从亚得里亚海(沿着阿布鲁佐地区海岸)捕获的122条棕鲷(Sepia officinalis)胃肠道中提取微塑料的方法,以测量其在研究较少的物种中的数量。胃肠内容物的提取方法采用10%氢氧化钾。98/122例(80.32-95% CI=73.27-87.37%)野生动物中检出微塑料,平均浓度为6.82±5.52 μPs/人。在这些片段中,有许多作者支持,黑色的片段是最具代表性的;然而,蓝色纤维和透明球也被分离出来。本研究与之前的研究一致,进一步关注了微塑料在海洋环境(表面,柱状,沉积物和动物)中的广泛扩散。所得结果为今后对这一公共卫生问题的调查提供了基础。
