Farmed European sea bass (Dicentrarchus labrax, Linnaeus, 1758) were collected during 2016 from one Sicilian fish farm that uses two different rearing systems - sea cage and concrete tank - for determination of polychlorinated biphenyls (PCB), organochlorine pesticides (OCP) and polycyclic aromatic hydrocarbons (PAH) residues by HRGC-MS/MS. Moreover, commercial feed was analysed. This study aimed to determine whether the different rearing systems affect the concentration of these compounds, and to assess the safety of cultured fish. PCBs represent the pollutants with the highest concentration; in particular, PCB138 and 153 have the highest concentration in almost all samples. Among OCPs, only 4,4'-DDE, 4,4'-DDD and 4,4'-DDT residues have been detected. Concerning PAHs, only fluorene and phenanthrene were detected, in both rearing systems. Although some residues of organic pollutants were found in the analysed samples, they were always below the MRLs, so the results suggest that farmed sea bass are safe for human consumption.
2016年，从西西里岛的一个养鱼场采集了养殖欧洲海鲈（Dicentrarchus labrax，林奈，1758年），该养鱼场使用两种不同的养殖系统——海水网箱和混凝土养殖池——通过高分辨气相色谱-串联质谱法测定多氯联苯（PCB）、有机氯农药（OCP）和多环芳烃（PAH）残留量。此外，还对商业饲料进行了分析。本研究旨在确定不同的养殖系统是否会影响这些化合物的浓度，并评估养殖鱼类的安全性。多氯联苯是浓度最高的污染物；特别是，PCB138和153在几乎所有样品中的浓度最高。在有机氯农药中，仅检测到4,4'-滴滴伊、4,4'-滴滴滴和4,4'-滴滴涕残留。关于多环芳烃，在两种养殖系统中均仅检测到芴和菲。尽管在分析的样品中发现了一些有机污染物残留，但它们始终低于最大残留限量，因此结果表明养殖海鲈供人类食用是安全的。
