For selected priority pollutants, like organochlorine pesticides, PAHs and PCBs, and mercury and cadmium, the transfer along marine food chains was assessed based on monitoring data. Comparison of the acquired body burden for marine fish and the toxicity thresholds for predating marine birds and mammals provides evidence for the relevance of contaminant uptake with the food and the liability for secondary poisoning. As a consequence, contaminant residues in prey organisms (critical body burden) should be used for marine hazard and risk assessments. Evaluations solely from aquatic exposure concentrations are not adequate to account for potential secondary effects in marine ecosystems.
对于选定的优先污染物，如有机氯农药、多环芳烃和多氯联苯，以及汞和镉，基于监测数据评估了其在海洋食物链中的转移情况。将海洋鱼类体内积累的污染物负荷与以其为食的海洋鸟类和哺乳动物的毒性阈值进行比较，为通过食物摄取污染物的相关性以及二次中毒的可能性提供了证据。因此，猎物生物体内的污染物残留（临界污染物负荷）应用于海洋危害和风险评估。仅根据水生生物接触浓度进行评估不足以说明海洋生态系统中的潜在次生影响。
