摘　　要：我们曾对从意大利收集的金枪鱼、箭鱼、普通鸬鹚以及家燕体内的p,(?)-DDE、多氯联苯同类物(PCBs)、多氯二苯-p-二恶英(PCDDs)、多氟二苯并呋喃(PCDFs)以及多氟萘(PCNs)浓度进行过测量。PCBs在金枪鱼、箭鱼、鸬鹅以及家燕肝脏内的平均浓度分别为930、745、1420和1230ng PCBs/g湿重,金枪鱼、箭鱼、鸬鹅以及家燕肝脏内的p,(?)-DDE平均浓度分别为82、135、166和95ng DDE/g湿重,在分析的所有样品中都发现有PCNs,不过浓度小于所报道的波罗的海生物体内的PCNs浓度。PCBs,特别是非正交、共面的PCBs占金枪鱼和箭鱼体内总毒性当量的80%～90%。鸬鹚和家燕体内PCDDs/DFs对毒性当量(TEQs)的相对贡献与鱼类相比更大一些。鸬鹚和家燕体内PCDD/DF同类物分别占总毒性当量的80%和45%。Concentrations of p,p'-DDE, polychlorinated biphenyl congeners (PCBs), polychlorinated-dibenzo-p-dioxins (PCDDs), -dibenzofurans (PCDFs) and -naphthalenes (PCNs) were measured in bluefin tuna, swordfish, common cormorants, and barn swallows collected from Italy. Average concentrations of PCBs in livers of tuna, swordfish, cormorant, and swallows were 930, 745, 1420 and 1230 ng PCBs g^-1, w.w. respectively. p,p'-DDE was found in tuna, swordfish, cormorant, and swallow livers at mean concentrations of 82, 135, 166 and 95 ng DDE g^-1, w.w. respectively. PCNs were found in all the samples analyzed, although at concentrations less than those reported for biota from the Baltic Sea. PCBs, particularly, non-orthocoplanar PCBs accounted for 80–90% of the total TEQs in tuna and swordfish. Relative contribution of PCDDs/DFs to TEQs was greater in cormorants and swallows compared to that in fishes. PCDD/DF congeners accounted for up to 80 and 45% of the total TEQs in cormorants and swallows, respectively.
