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)

• 毒性总结

PCB的作用机制因具体类型而异。类似于二噁英的PCB会与芳香烃受体结合，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I相和II相酶的表达，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还可能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干扰，这可以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)

  摘要：

  本文介绍了当煤和木材经过受控燃烧实验时针对一系列持久性有机污染物（POPs）得出的排放因子（EFs），旨在模拟空间供暖的家庭燃烧。排放了各种各样的持久性有机污染物，煤炭的排放量高于木材的排放量。对于颗粒物，PM10（大约10 g / kg燃料）和多环芳烃（对于sigmaPAHs大约100 mg / kg燃料）获得了最高的EF。对于氯化物，多氯联苯（PCB）的EF最高，而多氯萘（PCN），二苯并-对-二恶英（PCDD）和二苯并呋喃（PCDF）的丰度较低。对于sigmaPCB，EF大约为1000 ng / kg燃料，对于sigmaPCNs大约为100s ng / kg燃料，对于sigmaPCDD / Fs大约为100 ng / kg燃料。该研究证实，一氯化至三氯化二苯并呋喃Cl1,2,3DFs是低温燃烧过程（如煤炭和木材的国内燃烧）的有力指标。结论是，在固体燃料燃烧期间通常形成许多PCB和PC

  日期：1995.7

  Physical, spectral and chromatographic data for all 209 individual PCB congeners is presented. The individual congeners were synthesized and then isolated and purified. Recent emphasis on the source of the toxicity of commercial PCB formulations has increased the need for a complete set of the PCB congeners. Through the use of two capillary GC columns: 40% octadecyl/ 15% phenyl methyl siloxane and 50% phenyl methyl siloxane, it was possible to separate 201 PCB congeners with only four unresolved pairs. The data compiled in this study for all 209 congeners will aid in the identification of selected individual components of these environmental pollutants. The use of this data also presents the opportunity for the improved quantification of the commercial PCB formulations.
