Metabolite Identification
Common Name1,2,7,8-Tetrachlorodibenzo-P-dioxin
Description2,3,6,7-Tetrachlorodibenzo-p-dioxin belongs to the class of organic compounds known as chlorinated dibenzo-p-dioxins. These are organic compounds containing a chlorine atom attached to a dibenzo-p-dioxin moiety. Based on a literature review very few articles have been published on 2,3,6,7-Tetrachlorodibenzo-p-dioxin. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1,2,7,8-tetrachlorodibenzo-p-dioxin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1,2,7,8-Tetrachlorodibenzo-P-dioxin 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.
