GC/ECD and GC/MS. Brominated, bromochlorinated, and chlorinated methyl derivatives of phenols and OH-PCBs were synthesized to be used as authentic reference standards. More than 100 PHCs were indicated in the plasma, and among those a total of 9 monocyclic brominated or chlorinated phenol-, guaiacol-, and/or catechol-type compounds were identified as their methylated derivatives. The two major compounds
越来越多的研究报告了保留在人类和野生生物血液中的酚类卤代化合物(PHC)。这些初级化学品可能是工业化学品。代谢产物,如聚氯联苯酚(OH-PCBs);或自然起源。本研究旨在鉴定迄今未知的人血浆中具有与已知具有内分泌干扰活性的PHC一致的化学结构的PHC。为此,将来自瑞典的10位随机选择的男性献血者的血浆样本汇总起来并通过GC / ECD和GC / MS进行分析。合成了苯酚和OH-PCBs的溴代,溴代氯代和氯代甲基衍生物,以用作可靠的参考标准品。血浆中指示有100多种PHC,在这些化合物中,总共鉴定出9种单环溴化或氯化酚,愈创木酚和/或儿茶酚型化合物为它们的甲基化衍生物。两种主要化合物是2,4,6-三溴苯酚和五氯苯酚。在两个极性不同的气相色谱柱上,在结构上鉴定出38个OH-PCB同类物。建议在其母体PCB同系物的背景下OH-PCB代谢物的起源。在男性血浆中鉴定出的其他PHC是三氯生(5-氯-2-
