The levels of 13 polycyclic aromatic hydrocarbons (PAH) were determined by an HPLC method with fluorescence and UV detection and by a GC/MS technique in smoked fishery products from modern smoking kilns with external smoke generation and from traditional smoking kilns. The average benzo(a)pyrene (BaP) concentration of all 35 samples from commercial smoking kilns with external smoke generation was 0.1 microgram/kg (wet weight) and the sum of the carcinogenic compounds determined in the study, i.e. benz(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(a)pyrene, dibenz(a,h)anthracene and indeno(1,2,3-c,d)pyrene did not exceed 4.5 micrograms/kg (wet weight). The BaP levels of the 27 smoked fish samples from traditional kilns ranged from 0.2 microgram/kg to 4.1 micrograms/kg, with a mean value of 1.2 micrograms BaP/kg. The average concentration of the sum of the carcinogenic compounds was 9.0 micrograms/kg. Large variations were found in the content of the non-carcinogenic PAHs phenanthrene, anthracene, fluoranthene and pyrene in all samples from both types of smoking kilns.
采用高效液相色谱法（配有荧光和紫外检测）以及气相色谱/质谱联用技术，测定了来自具有外部烟雾产生装置的现代熏制窑炉和传统熏制窑炉的烟熏渔业产品中13种多环芳烃（PAH）的含量。来自具有外部烟雾产生装置的商业熏制窑炉的所有35个样品中，苯并(a)芘（BaP）的平均浓度为0.1微克/千克（湿重），该研究中测定的致癌化合物（即苯并(a)蒽、 Chrysene、苯并(b)荧蒽、苯并(k)荧蒽、苯并(a)芘、二苯并(a,h)蒽和茚并(1,2,3-c,d)芘）的总量不超过4.5微克/千克（湿重）。来自传统窑炉的27个烟熏鱼样品的BaP含量在0.2微克/千克至4.1微克/千克之间，平均值为1.2微克BaP/千克。致癌化合物总量的平均浓度为9.0微克/千克。在这两种类型熏制窑炉的所有样品中，非致癌性PAH（菲、蒽、荧蒽和芘）的含量存在很大差异。
