Polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and organochlorine pesticides (OCPs) were quantified in muscle tissue of European hake, an ecologically and commercially important species. Samples were collected from the Western Mediterranean, in seven different stations at different depths and a batch was bought in a local market. PCBs are the dominant pollutants, but the overall concentrations do not show significant differences between the different specimens analyzed from various locations, with the exception of the concentration of PCBs at a shallow station close to the River Besòs mouth. This probably suggests that generally the pollutants in hake from the Western Mediterranean derive from historical and non-point sources. The occurrence of pollutants is widespread in the samples but their concentration is below recommended legal limits for fish or other foodstuffs.
在欧洲无须鳕（一种具有生态和商业重要性的物种）的肌肉组织中，对多环芳烃（PAHs）、多氯联苯（PCBs）和有机氯农药（OCPs）进行了定量分析。样本采集自西地中海的七个不同深度的站点，还有一批是在当地市场购买的。多氯联苯是主要污染物，但除了靠近贝索斯河口的一个浅站点的多氯联苯浓度外，从不同地点分析的不同样本之间的总体浓度没有显著差异。这可能表明，一般来说，西地中海无须鳕体内的污染物来自历史和非点源。污染物在样本中广泛存在，但其浓度低于鱼类或其他食品的法定推荐限值。
