The dietary intake of arsenic (As), cadmium (Cd), mercury (Hg), lead (Pb), hexachlorobenzene (HCB), polychlorinated naphthalenes (PCNs), polycyclic aromatic hydrocarbons (PAHs), polychlorinated diphenyl ethers (PCDEs), polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) by elite sportsmen and sportswomen of Catalonia, Spain, was assessed. In 2000, food samples were randomly acquired in various cities of Catalonia. Analysis of the above pollutants were determined according to the appropriate analytical techniques (ICP-MS, HRGC/HRMS, HPLC). In general terms, elite sportsmen and sportswomen showed a higher intake of Cd, Hg, Pb, HCB, PCNs, PCDD/Fs and PAHs than the general population, while it was lower for PCDEs (both sexes), and PCBs and PBDEs (women). According to the FAO/WHO provisional tolerable weekly intake (PTWI) for metals, the WHO tolerable daily intake (TDI) for HCB, and the US EPA's reference dose (RfD) for PAHs, the dietary intakes of environmental pollutants should not mean a potential toxic hazard. However, the WHO-TDI for PCDD/Fs and "dioxin-like" PCBs is exceeded in sportsmen. The current results indicate that the consumption of those food groups showing the highest contribution to the intake of these pollutants should be diminished. In relation to this, the reduction of the consumption of dairy products and cereals would be important.
对西班牙加泰罗尼亚地区男女优秀运动员的砷（As）、镉（Cd）、汞（Hg）、铅（Pb）、六氯苯（HCB）、多氯萘（PCNs）、多环芳烃（PAHs）、多氯二苯醚（PCDEs）、多溴二苯醚（PBDEs）、多氯联苯（PCBs）以及多氯二苯并对二恶英和多氯二苯并呋喃（PCDD/Fs）的膳食摄入量进行了评估。2000年，在加泰罗尼亚的各个城市随机采集了食物样本。根据适当的分析技术（电感耦合等离子体质谱法、高分辨气相色谱/高分辨质谱法、高效液相色谱法）对上述污染物进行分析。总体而言，优秀男女运动员摄入的镉、汞、铅、六氯苯、多氯萘、多氯二苯并对二恶英和多氯二苯并呋喃以及多环芳烃高于普通人群，而多氯二苯醚（男女皆是）以及多氯联苯和多溴二苯醚（女性）的摄入量则低于普通人群。根据粮农组织/世界卫生组织金属的暂定每周耐受摄入量（PTWI）、世界卫生组织六氯苯的每日耐受摄入量（TDI）以及美国环境保护局多环芳烃的参考剂量（RfD），环境污染物的膳食摄入量不应意味着潜在的毒性危害。然而，运动员的多氯二苯并对二恶英和多氯二苯并呋喃以及“类二恶英”多氯联苯的世界卫生组织每日耐受摄入量被超过。目前的结果表明，应减少那些对这些污染物摄入量贡献最大食物组的消费。与此相关，减少乳制品和谷物的消费将很重要。
