Abstract

We characterized the presence of plastics in different organs of the gilthead seabream (Sparus aurata) and European seabass (Dicentrarchus labrax) from some off-shore aquaculture facilities of the Mediterranean Sea. Plastics were detected in 38% of analyzed fish. Higher contamination was observed in fish from Turkey and Greece with respect to Italy, without significant differences between the geographical areas. Plastics accumulated mostly in the gastrointestinal tract and, to a lower extent, in the muscle, which represents the edible part of fish. Based on the particle detected, a maximum amount of 0.01 plastic/g wet weight (w.w.) can occur in muscles, suggesting a low input for humans through consumption. A large portion of the particles identified was represented by man-made cellulose-based fibers. The characterization of the polymeric composition suggests that plastics taken up by fish can have land-based and pelagic origins, but plastics can be introduced also from different aquaculture practices.

地中海近海水产养殖设施中海鲈和海鲷的塑料污染

我们对来自地中海一些近海水产养殖设施的金头海鲷(Sparus aurata)和欧洲海鲈(Dicentrarchus labrax)的不同器官中存在的塑料进行了表征。在被分析的鱼类中，有38%被检测出塑料。土耳其和希腊的鱼类受污染程度高于意大利，但地理区域之间没有显著差异。塑料主要在胃肠道中积聚，在较低程度上，在肌肉中积聚，肌肉代表鱼的可食用部分。根据检测到的颗粒，肌肉中最多可出现0.01的塑料/g湿重(w.w.)，这表明人类通过摄入摄入的量很低。鉴定出的大部分颗粒是人造纤维素基纤维。聚合物组成的特征表明，鱼类吸收的塑料可能来自陆地和远洋，但塑料也可能来自不同的水产养殖做法。

期刊介绍： The Journal of Xenobiotics publishes original studies concerning the beneficial (pharmacology) and detrimental effects (toxicology) of xenobiotics in all organisms. A xenobiotic (“stranger to life”) is defined as a chemical that is not usually found at significant concentrations or expected to reside for long periods in organisms. In addition to man-made chemicals, natural products could also be of interest if they have potent biological properties, special medicinal properties or that a given organism is at risk of exposure in the environment. Topics dealing with abiotic- and biotic-based transformations in various media (xenobiochemistry) and environmental toxicology are also of interest. Areas of interests include the identification of key physical and chemical properties of molecules that predict biological effects and persistence in the environment; the molecular mode of action of xenobiotics; biochemical and physiological interactions leading to change in organism health; pathophysiological interactions of natural and synthetic chemicals; development of biochemical indicators including new “-omics” approaches to identify biomarkers of exposure or effects for xenobiotics.
