This study analyzed for the detection of the following trace elements: As, Cd, Cu, Hg, Pb, Se, Zn, in muscle of four widely traded and consumed marine fish species (Mullus surmuletus L., Merluccius merluccius L., Micromesistius poutassou (Risso, 1827), Scomber scombrus L.) selected for their wide trade and consumption. Mean concentrations found in fish muscle, irrespective of species, ranged from 3.61 to 105.49 (As); 0.01-0.08 (Cd); 0.74-4.71 (Cu); 0.09-1.10 (Hg); 0.02-0.58 (Pb); 0.30-2.88 (Se); 11.56-73.37 (Zn) mg/kg wet weight. As, Hg, Cu and Se concentrations showed a significant difference (p < 0.01) among the analyzed species in winter and in summer. Cd exhibited a significant difference (p < 0.01) only in summer. The maximum levels set for Hg, Cd and Pb by European Regulation No 1881/2006 were exceeded by 5 (8.9%), 1 (1.8%) and 4 (7.1%) samples, respectively. In particular the species exceeding the legal limits were red mullet for Cd and Pb, Atlantic mackerel and blue whiting for Hg and Pb.
砷、镉、铜、汞、铅、硒、锌，这些元素来自于四种广泛交易和食用的海洋鱼类（拟庸鲽、无须鳕、蓝圆鲹和鲐鱼），选择这些鱼类是因为它们的交易和消费范围广泛。不论物种如何，鱼类肌肉中的平均浓度范围从 3.61 到 105.49（砷）；0.01-0.08（镉）；0.74-4.71（铜）；0.09-1.10（汞）；0.02-0.58（铅）；0.30-2.88（硒）；11.56-73.37（锌）mg/kg 湿重。在冬季和夏季，分析的物种之间的砷、汞、铜和硒浓度存在显著差异（p<0.01）。镉仅在夏季表现出显著差异（p<0.01）。欧洲法规 1881/2006 为汞、镉和铅设定的最大限量分别有 5 个（8.9%）、1 个（1.8%）和 4 个（7.1%）样本超标。特别是红鲻鱼和鲐鱼的镉和铅、大西洋马鲛和蓝鳕鱼的汞和铅含量超过了法定限量。
