代谢

多氯联苯(PCBs)通过吸入、口服和皮肤接触途径被吸收。它们通过血液运输，通常与白蛋白结合。由于它们的亲脂性特性，它们倾向于在富含脂质的组织中积累，如肝脏、脂肪组织和皮肤。多氯联苯的代谢非常缓慢，并且根据氯化的程度和位置而有所不同。多氯联苯通过微粒体单加氧酶系统代谢，该系统由细胞色素P-450酶催化，转化为极性代谢物，这些代谢物可以与谷胱甘肽和葡萄糖醛酸结合。主要的代谢物是羟基化产物，通过胆汁和粪便排出。多氯联苯的缓慢代谢意味着它们倾向于在身体组织中积累。(L4, T6)

PCBs are absorbed via inhalation, oral, and dermal routes of exposure. They are trasported in the blood, often bound to albumin. Due to their lipophilic nature they tend to accumulate in lipid-rich tissues, such as the liver, adipose, and skin. Metabolism of PCBs is very slow and varies based on the degree and position of chlorination. PCBs are metabolized by the microsomal monooxygenase system catalyzed by cytochrome P-450 enzymes to polar metabolites that can undergo conjugation with glutathione and glucuronic acid. The major metabolites are hydroxylated products which are excreted in the bile and faeces. The slow metabolism of PCBs means they tend to accumulate in body tissues. (L4, T6)

毒理性

• 毒性总结

PCB的作用机制因具体类型而异。类似于二噁烷的PCB会与芳基烃受体结合，通过改变基因的转录来扰乱细胞功能，主要是通过诱导肝脏第一阶段和第二阶段酶的表达，特别是细胞色素P450家族。人们认为PCB的大多数毒性效应是Ah受体结合的结果。其他PCB被认为会干扰钙通道和/或改变大脑中的多巴胺水平。PCB还通过改变甲状腺激素的生成和与雌激素受体结合来引起内分泌紊乱，这可能会刺激某些癌细胞的生长并产生其他类雌激素效应，如生殖功能障碍。它们还会通过结合如uteroglobin等受体蛋白而生物累积。(A3, A4, A30, A66)

The mechanism of action varies with the specific PCB. Dioxin-like PCBs bind to the aryl hydrocarbon receptor, which disrupts cell function by altering the transcription of genes, mainly be inducing the expression of hepatic Phase I and Phase II enzymes, especially of the cytochrome P450 family. Most of the toxic effects of PCBs are believed to be results of Ah receptor binding. Other PBCs are believed to interfere with calcium channels and/or change brain dopamine levels. PCBs can also cause endocrine disurption by altering the production of thyroid hormones and binding to estrogen receptors, which can stimulate the growth of certain cancer cells and produce other estrogenic effects, such as reproductive dysfunction. They will bioaccumulate by binding to receptor proteins such as uteroglobin. (A3, A4, A30, A66)

  Polychlorobenzenes, polybromobenzenes, and polychloropolybromobenzenes (C6H6−nXn) were photolyzed in benzene solutions; the products were analyzed by the GC/MS method. Both dehalogenation and phenylation were shown to take place competitively, producing (poly)halobenzenes bearing one less halogen atom (C6H7−nXn−1) and (poly)halobiphenyls (C6H6−nXn−1–C6H5) as the major products. Besides these products

  多氯苯、多溴苯和多氯多溴苯（C6H6−nXn）在苯溶液中光解；产物采用 GC/MS 方法分析。脱卤和苯基化都显示出竞争性，产生少一个卤素原子的（多）卤代苯（C6H7-nXn-1）和（多）卤代联苯（C6H6-nXn-1-C6H5）作为主要产品。除了这些产品之外，三联苯是通过形成的卤代联苯的连续苯基化产生的。只有当通过 2-氯联苯的途径成为可能时，多氯苯才会形成相应的三联苯；然而，多溴苯可以通过中间形成的任何异构溴联苯产生三联苯。还显示通过氯原子的间迁移发生异构化的程度要小得多。
