Common Name | 1,2,3,4-Tetrachlorodibenzofuran |

Description | 1,2,3,4-Tetrachlorodibenzofuran belongs to the class of organic compounds known as polychlorinated dibenzofurans. These are organic compounds containing two or more chlorine atoms attached to a dibenzofuran moiety. Most CDFs are produced in very small amounts as unwanted impurities of certain products and processes utilizing chlorinated compounds. 1,2,3,4-Tetrachlorodibenzofuran is an extremely weak basic (essentially neutral) compound (based on its pKa). 1,2,3,4-Tetrachlorodibenzofuran is a potentially toxic compound. The bacteria Sphingomonas, Brevibacterium, Terrabacter, and Staphylococcus auricularis degrade dibenzofuran to 2,2',3-trihydroxybiphenyl via dibenzofuran 4,4a-dioxygenase. Chlorinated dibenzofurans (CDFs) are a family of chemical that contain one to eight chlorine atoms attached to the carbon atoms of the parent chemical, dibenzofuran. Specifically AhR binds to the PCDF, translocates it to the nucleus and together with hydrocarbon nuclear translocator (ARNT) and xenobiotic responsive element (XRE) increases the expression of CYP1A1 and aryl hydrocarbon hydroxylase (CYP1B1). The resulting AhR mediated activation and alteration leads to body weight loss, cancer and thymic atrophy (characteristic of immune and endocrine disruption) which are common toxic responses to PCDFs and related toxic halogenated aryl hydrocarbons. Of these 135 compounds, those that contain chlorine atoms at the 2,3,7,8-positions of the parent dibenzofuran molecule are especially harmful. AhR signalling also alters proteasomal degradation of steroid hormone receptors, alters cellular UVB stress response and changes the differentiation of certain T-cell subsets. Halogenated dibenzofurans (PCDFs and PBDFs) bind the aryl hydrocarbon receptor (AhR), which increases its ability to activate transcription in the XRE (xenobiotic resoponse element) promoter region. Only a few of the 135 CDF compounds have been produced in large enough quantities so that their properties, such as color, smell, taste, and toxicity could be studied. Skin and eye irritations, especially severe acne, darkened skin color, and swollen eyelids with discharge are the most obvious health effects of the CDF poisoning. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1,2,3,4-tetrachlorodibenzofuran is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1,2,3,4-Tetrachlorodibenzofuran is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources. |
