Metabolite Identification
Common NameHeptachlor
DescriptionHeptachlor, also known as 3-chlorochlordene or heptamul, belongs to the class of organic compounds known as vinyl chlorides. These are vinyl halides in which a chlorine atom is bonded to an sp2-hybridised carbon atom. Heptachlor is possibly neutral. Heptachlor is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. It is readily metabolized by liver microsomes into heptachlor epoxide, its most persistent and toxic metabolite, which is mainly stored in adipose tissue. It is one ingredient of cigarette. It non-competitively blocks neurotransmitter action at gamma-amino butyric acid receptors, resulting in overstimulation of the nervous system. Treatment is symptomatic and is aimed at controlling convulsions, coma, and respiratory depression. Heptachlor is a manufactured cyclodiene organochlorine insecticide. Heptachlor epoxide is excreted in the urine and faeces. Heptachlor is readily absorbed by the skin, lungs and gastrointestinal tract. Heptachlor poisoning may cause convulsions, vomiting, seizures, confusion, incoordination, excitability, coma, hypotension, and respiratory failure. This compound has been identified in human blood as reported by (PMID: 31557052 ). Heptachlor is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Heptachlor 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.
