A total of 84 samples of wild and farmed fish, cephalopods and fish oils for animal feeding, traded in Spain, were analysed for polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and dioxin-like polychlorinated biphenyls (dl-PCBs) in 2009-2012, by gas chromatography-ion trap tandem mass spectrometry (GC-MS-MS). The method was optimised for screening at moderate costs, allowing PCDD/Fs determination at 1 pg World Health Organization-toxic equivalent quantities (WHO-TEQ) g⁻¹ wet weight (w w) and dl-PCBs at 0.02 pg WHO-TEQ g⁻¹ w w. Concentrations in fish and cephalopods ranged from values below the limit of detection to 1.7 pg g⁻¹ WHO-TEQ sum PCDD/Fs and dl-PCBs, considered as safe with regard to EU legislation. Higher levels were found in cod livers (5.4-54.2) and fish oils (3.3-30.7), with one noncompliant sample in each group.
2009-2012 年，通过气相色谱-离子阱串联质谱法（GC-MS-MS）对西班牙交易的 84 个野生和养殖鱼类、头足类动物和动物饲料用鱼油样本进行了多氯二苯并对二恶英和呋喃（PCDD/Fs）以及类似二恶英的多氯联苯（dl-PCBs）的检测。该方法是针对中等成本的筛选进行了优化，可将 PCDD/Fs 的检测下限确定为 1pg 世界卫生组织毒性当量（WHO-TEQ）g⁻¹ 湿重（w w），dl-PCBs 的检测下限为 0.02pg WHO-TEQ g⁻¹ w w。鱼类和头足类动物中的浓度从低于检测限到 1.7pg g⁻¹ WHO-TEQ 总量 PCDD/Fs 和 dl-PCBs 不等，被认为符合欧盟法规的安全性标准。在鳕鱼肝脏（5.4-54.2）和鱼油（3.3-30.7）中发现了更高的浓度，每组中都有一个不符合标准的样本。
