- 安全声明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
