Development of a Vortex-Assisted Dispersive Liquid-Liquid Microextraction (VA-DLLME) and LC-MS/MS Procedure for Simultaneous Determination of Fipronil and its Metabolite Fipronil Sulfone in Tomato Fruits

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.

Toxicity and Neurophysiological Effects of Fipronil and Its Oxidative Sulfone Metabolite on European Corn Borer Larvae (Lepidoptera: Crambidae)

Pesticide Biochemistry and Physiology, 2001
Abstract The phenylpyrazole insecticide fipronil is the first compound of its class to be registered for commercial use. The mode of action of this class of insecticides involves antagonism of the inhibitory neurotransmitter, γ-aminobutyric acid (GABA).

Maternal exposure to fipronil results in sulfone metabolite enrichment and transgenerational toxicity in zebrafish offspring: Indication for an overlooked risk in maternal transfer?

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 ...
