The concentrations of polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs) and biphenyls (PCBs) in samples from 14 fish and seafood species widely consumed by the population of Catalonia, Spain, were measured. These samples were randomly purchased independently of their geographical origin. The intake of PCDD/Fs and PCBs through consumption of these species was also estimated for various age and sex groups of this population. The highest and lowest levels of PCDD/Fs and dioxin-like PCBs (DL-PCBs) were found in red mullet and shrimp, respectively. For a standard adult man (70 kg body weight), the intake of PCDD/Fs plus DL-PCBs through consumption of fish and other seafood was estimated to be 38.0 pg WHO-TEQ/day. Tuna, hake, and sardine were the species with the highest contribution to this intake. The results of this study indicate that, in general terms, the dietary habits of the population of Catalonia (Spain) regarding fish and seafood consumption do not contribute remarkably to increase PCDD/F and DL-PCB intake.
对西班牙加泰罗尼亚地区民众广泛食用的14种鱼类和海鲜样本中的多氯二苯并 - 对二恶英（PCDDs）、二苯并呋喃（PCDFs）和多氯联苯（PCBs）浓度进行了测量。这些样本是随机购买的，与它们的地理来源无关。还针对该地区不同年龄和性别的人群估算了通过食用这些物种摄入的PCDD/Fs和PCBs量。PCDD/Fs和类二恶英多氯联苯（DL - PCBs）的最高和最低含量分别出现在红鲻鱼和虾中。对于一名标准成年男性（体重70千克），通过食用鱼类和其他海鲜摄入的PCDD/Fs加DL - PCBs量估计为38.0皮克WHO - TEQ/天。金枪鱼、无须鳕和沙丁鱼是对这一摄入量贡献最大的物种。这项研究的结果表明，总体而言，西班牙加泰罗尼亚地区民众在鱼类和海鲜消费方面的饮食习惯对增加PCDD/F和DL - PCB摄入量的贡献并不显著。
