Reported as not meeting GHS hazard criteria by 3 of 3 companies. For more detailed information, please visit ECHA C&L website. - 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)

标题:Physical,Spectral And Chromatographic Properties Of All 209 Individual Pcb Congeners
摘要: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.
