Non-ortho (coplanar) PCBs 77, 126 and 169 were determined in a number of fish species from the Swedish coastal environment, using either supercritical fluid extraction (SFE) or the traditional liquid/liquid extraction followed by HPLC separation on porous graphitic carbon (PGC) column prior to GC/MS analysis. While PCB 77 showed the highest concentration level, the TEQ value for PCB 126 was dominant in virtually all the samples analysed. The toxic equivalents, however, indicated some differences in analytical data between 1990 and 1992/93 but these are not significant probably owing to the short period in between.
采用超临界流体萃取（SFE）或传统的液/液萃取方法，随后在多孔石墨化碳（PGC）柱上进行HPLC分离，然后进行GC/MS分析，测定了瑞典沿海环境中多种鱼类体内的非邻位（共面）多氯联苯77、126和169。虽然多氯联苯77的浓度水平最高，但在几乎所有分析的样品中，多氯联苯126的毒性当量值占主导地位。然而，毒性当量表明1990年和1992/93年之间的分析数据存在一些差异，但由于间隔时间较短，这些差异可能并不显著。
