在代表性商业 PCB 制剂中测定了共面 PCB 的三种同系物(非邻氯取代的多氯联苯)。 3,3',4,4'-四氯联苯含量最高的是 Kanechron 400(8500 微克/克)和 Aroclor 1248(6060 微克/克),其次是 Kanelors 300、500 和 600,以及 Aroclor 1242、1254 和 1260。这些混合物中还检测到有毒的3,3',4,4',5-五氯联苯和3,3',4,4',5,5'-六氯联苯。最高浓度的 3,3',4,4',5-五氯联苯出现在 Kanelor 400(89.3 微克/克)和 Aroclor 1248(62.3 微克/克)中,其次是 Kanelors 500、300 和 600,以及 Aroclors 1254、1242 和 1260。所有 Kanelor 混合物中均检测到了 3,3',4,4',5,5'-六氯联苯,其中 Kanelor 500 中浓度最高(1.16 微克/克)。然而,在 Aroclor 混合物中,仅在 Aroclor 1254 中检测到,浓度为 0.66 微克/克。鉴于多氯联苯对环境的广泛污染,多氯联苯混合物中这些有毒成分的重要性值得考虑。
Three congeners of coplanar PCBs (non-o-o'-chlorine-substituted polychlorinated biphenyls) were determined in representative commercial PCB preparations. The 3,3',4,4'-tetrachlorobiphenyl was highest in Kanechlor 400 (8500 micrograms/g) and Aroclor 1248 (6060 micrograms/g) followed by Kanechlors 300, 500, and 600 and Aroclors 1242, 1254, and 1260 in that order. The toxic 3,3',4,4',5-pentachlorobiphenyl and 3,3',4,4',5,5'-hexachlorobiphenyl were also detected in those mixtures. The highest concentrations of 3,3',4,4',5-pentachlorobiphenyl were found in Kanechlor 400 (89.3 micrograms/g) and Aroclor 1248 (62.3 micrograms/g) followed by Kanechlors 500, 300, and 600 and Aroclors 1254, 1242, and 1260 in that order. The 3,3',4,4',5,5'-hexachlorobiphenyl was detected in all Kanechlor mixtures, with the highest concentration (1.16 micrograms/g) in Kanechlor 500. However, among Aroclor mixtures, it was detected only in Aroclor 1254 at a concentration of 0.66 micrograms/g. The importance of these toxic constituents in PCB mixtures is worth considering in view of widespread pollution of the environment by PCBs.
