Fipronil is a member of phenylpyrazole insecticide, which was widely used in agriculture to kill pests [1-2]. It can also form metabolite, such as fipronil sulfone by oxidation process, which is more toxic than parent compound [3-4]. Fipronil sulfone can persist for longer duration, which can easily bind to lipid-rich matrices and get into food chain ...

Fipronil (FIP) is a broad-spectrum insecticide used in the industrial, residential and agricultural sectors, which presents environmental and human health risks. Studies report its presence in aquatic environments in several countries, but in Brazil reports are scarce.

ELECTROPHORESIS, 2019
AbstractFipronil is an insecticide that is not approved in the European Union in food. In 2017, fipronil was involved in a European health alert due to its presence in fresh hen eggs because of an illicit use in poultry farms, so reliable methods are needed to determine fipronil and its main metabolites in these matrixes.

Fipronil is a most widely used insecticide. It has been found to be highly toxic to insects with alarming decline in honey bees' population. It has shown to cause severe contamination of soil and water. The present study was undertaken to understand the degradation of fipronil and its metabolite fipronil sulfone using actinomycetes.

Journal of Separation Science
ABSTRACT An ultra‐high performance liquid chromatography‐tandem mass spectrometry (UHPLC‐MS/MS) method was developed and validated for the simultaneous determination of fipronil and its three metabolites (fipronil sulfone, fipronil sulfide, and fipronil desulfinyl) in zebrafish tissues.

Chemical Research in Toxicology, 1998
Fipronil, an N-phenylpyrazole with a trifluoromethylsulfinyl substituent, initiated the second generation of insecticides acting at the gamma-aminobutyric acid (GABA) receptor to block the chloride channel. The first generation includes the polychlorocycloalkanes alpha-endosulfan and lindane.

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology
Fipronil sulfone is a persistent oxidative metabolite of the insecticide fipronil, frequently detected in aquatic systems and known to exert neurotoxic effects on non-target organisms. Despite its environmental relevance, the developmental impacts of fipronil sulfone remain underexplored.

The Journal of Pharmacology and Experimental Therapeutics, 2005
Fipronil sulfone, a major metabolite of fipronil in both insects and mammals, binds strongly to GABA receptors and is thought to play a significant role in poisoning by fipronil. To better understand the mechanism of selective insecticidal action of fipronil, we examined the effects of its sulfone metabolite on GABA- and glutamate-activated chloride ...

Food Analytical Methods, 2019
A rapid, simple, inexpensive, and reliable vortex-assisted dispersive liquid-liquid microextraction (VA-DLLME) method was developed for the determination of fipronil and its major metabolite, fipronil sulfone, in tomato fruits using liquid chromatography tandem mass spectrometry (LC-MS/MS). No salting-out or cleanup steps were required after extraction.

Environmental Pollution, 2019
Ecotoxicological studies show the association between pesticide pollution and transgenerational toxicity in aquatic organisms. However, a less considered risk is that many pesticides can be metabolized and transferred to offspring as new toxicants. In this study, we used zebrafish to evaluate the maternal transfer risk of fipronil (FIP), which is a ...
