据估计，西班牙加泰罗尼亚的普通人口每天通过食用14种可食用海洋物种摄入砷(As)、镉(Cd)、汞(Hg)和铅(Pb)。还评估了这种摄取所产生的健康风险。2005年3-4月，在加泰罗尼亚的6个城市随机采集了沙丁鱼、金枪鱼、凤尾鱼、鲱鱼、旗鱼、鲑鱼、鳕鱼、红鱼、比目鱼、墨鱼、鱿鱼、文蛤、贻贝和虾的样品。用电感耦合等离子体质谱(ICMS)测定砷、镉、汞、铅的含量。根据最新的鱼类和海鲜消费数据，计算了人口中8个年龄/性别组别的每日摄入量。红鱼的As含量最高，为16.6 mU g/g鲜重，而文蛤和贻贝的Cd含量最高，分别为0.14和0.13 mU g/g鲜重。剑鱼(1.93微克/克鲜重)、贻贝和鲑鱼(0.15微克/克鲜重和0.10微克/克鲜重)的汞和铅含量最高。男性老年人通过鱼和海鲜摄入的金属最多，分别为As(217.7µg/d)、Cd(1.3 4µg/d)和Pb(2.48µg/d)，而汞的摄入量则为男性成年人(9.89µg/d)。通过鱼和海鲜摄入这些元素的每日摄入量与暂定的每周可耐受摄入量(PTWI)进行比较。加泰罗尼亚地区人群对As、Cd、Pb和总汞的摄入量均低于各自的PTWI值。然而，男孩甲基汞的估计摄入量为1.96微克/公斤/周，超过了临时标准。
The daily intake of arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb) through the consumption of 14 edible marine species by the general population of Catalonia, Spain, was estimated. Health risks derived from this intake were also assessed. In March-April 2005, samples of sardine, tuna, anchovy, mackerel, swordfish, salmon, hake, red mullet, sole, cuttlefish, squid, clam, mussel, and shrimp were randomly acquired in six cities of Catalonia. Concentrations of As, Cd, Hg, and Pb were determined by ICP-MS. On the basis of recent fish and seafood consumption data, the daily intake of these elements was calculated for eight age/sex groups of the population. The highest As concentrations were found in red mullet, 16.6 mu g/g of fresh weight, whereas clam and mussel (0.14 and 0.13 mu g/g of fresh weight, respectively) were the species with the highest Cd levels. In turn, swordfish (1.93 mu g/g of fresh weight) and mussel and salmon (0.15 and 0.10 mu g/g of fresh weight) showed the highest concentrations of Hg and Pb, respectively. The highest metal intake through fish and seafood consumption corresponded to As (217.7 mu g/day), Cd (1.34 mu g/day), and Pb (2.48 mu g/day) for male seniors, whereas that of Hg was observed in male adults (9.89 mu g/day). The daily intake through fish and seafood consumption of these elements was compared with the provisional tolerable weekly intakes (PTWI). The intakes of As, Cd, Pb, and total Hg by the population of Catalonia were below the respective PTWI values. However, the estimated intake of methylmercury for boys, 1.96 mu g/kg/week, was over the PTWI.
