Fatty acids (FAs) composition, 24 persistent organic pollutants (POPs), and 16 trace elements were examined in small pelagic fish (sardine, anchovy, round sardinella, chub and horse mackerels) caught by a fishing fleet for more than three years in the eastern Mediterranean Sea. Five Unmix source profiles associated with both sources, such as overlapping diet, including low-niche marine organisms and inputs from the surrounding environmental compartments were resolved. Inorganic compounds were notably more abundant in fish tissue than organochlorine xenobiotics. Comparison with the values of toxicological parameters revealed that the examined fish species are safe for human consumption, while the content of FAs emphasized the studied species as a valuable source of nutrients. A significant linear correlation was not observed between the 18 FAs and lipophilic organochlorines. Based on the obtained database, future assessments of the quality of edible fish species and the aquatic environment of the eastern Mediterranean Sea, which is known as an important fishing ground, could be significantly improved.
在东地中海，一个捕鱼船队在三年多的时间里捕获了小型洄游鱼类（沙丁鱼、凤尾鱼、圆鲹、鲱鱼和马鲛鱼），对其进行了脂肪酸 (FA) 组成、24 种持久性有机污染物 (POPs) 和 16 种微量元素的检测。解析出与两种来源相关的五个 Unmix 源谱，如重叠的饮食，包括低生态位的海洋生物和来自周围环境隔室的输入。与毒理学参数的值进行比较后发现，所研究的鱼类物种对人类食用是安全的，而 FA 的含量强调了这些研究物种是营养物质的宝贵来源。18 种脂肪酸与脂溶性有机氯农药之间未观察到显著的线性相关性。基于获得的数据库，可以显著改进对东地中海（一个已知的重要捕鱼区）食用鱼类物种质量和水生环境的未来评估。
