Metabolite Identification
Common NameFipronil
DescriptionFipronil belongs to the class of organic compounds known as phenylpyrazoles. Phenylpyrazoles are compounds containing a phenylpyrazole skeleton, which consists of a pyrazole bound to a phenyl group. Based on a literature review very few articles have been published on Fipronil. This compound has been identified in human blood as reported by (PMID: 31557052 ). Fipronil is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Fipronil 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.
