Analytical Method for Fipronil and Fipronil Sulfone in Livestock Products Using LC-MS/MS

Food Hygiene and Safety Science (Shokuhin Eiseigaku Zasshi), 2020
A rapid and sensitive method for the simultaneous determination of fipronil and fipronil sulfone (metabolite B) in livestock products was developed. The analytes were extracted from samples with acidic acetonitrile. The crude extracts were subjected to clean-up step using neutral alumina cartridge column.

Polypyrrole‐coated rubber foam sorbent for extraction of fipronil and fipronil sulfone in tea

SEPARATION SCIENCE PLUS, 2023
Abstract A polypyrrole‐coated rubber foam sorbent with a steel wire insert was developed for the magnetic solid phase extraction of fipronil and fipronil sulfone from tea samples for analysis by a gas chromatography‐electron capture detector.

Synthesis of fipronil sulfide, an active metabolite, from the parent insecticide fipronil

Tetrahedron Letters, 2001
Abstract A convenient procedure for the synthesis of fipronil sulfide, one of several active metabolites identified from the insecticide fipronil, has been developed. Reduction of fipronil with trifluoroacetic anhydride–sodium iodide in acetone, followed by flash chromatography afforded fipronil sulfide in 60% yield and >99.9 percent purity.

Compatibility of entomopathogenic nematodes with fipronil

Journal of Helminthology, 2005
AbstractThe survival and infectivity of infective juveniles (IJs) of three species of entomopathogenic nematodes, Steinernema carpocapsae Weiser, S. arenarium (Artyukhovsky) (Rhabditida: Steinernematidae) and Heterorhabditis bacteriophora Poinar (Rhabditida: Heterorhabditidae), were determined after exposure to different concentrations (250, 500, 1000 ...

Sorption Kinetics of Fipronil on Soils

Bulletin of Environmental Contamination and Toxicology, 2014
Sorption kinetics of fipronil was studied on five soils of varying physico-chemical properties by batch equilibration method. Fipronil sorption on soils conformed to pseudo-second order kinetics and both the initial uptake rate and rate constant had a significant and positive correlation with clay content.

Rapid and Sensitive Quantitation of Fipronil and Its Metabolites Fipronil Sulfone, Fipronil Sulfide, and Fipronil Desulfinyl in Zebrafish Tissues by UHPLC‐MS/MS

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.

Fipronil insecticide toxicology: oxidative stress and metabolism

Critical Reviews in Toxicology, 2016
Fipronil (FIP) is widely used across the world as a broad-spectrum phenylpyrazole insecticide and veterinary drug. FIP was the insecticide to act by targeting the γ-aminobutyric acid (GABA) receptor and has favorable selective toxicity towards insects rather than mammals.

Fipronil and imidacloprid reduce honeybee mitochondrial activity

Environmental Toxicology and Chemistry, 2014
Abstract   Bees have a crucial role in pollination; therefore, it is important to determine the causes of their recent decline. Fipronil and imidacloprid are insecticides used worldwide to eliminate or control insect pests.

How Can the Fipronil Insecticide Access Phloem?

Journal of Agricultural and Food Chemistry, 2008
Seeds of sunflower plants coated with the fipronil (14)C-insecticide were allowed to grow in the greenhouse. The distribution of the (14)C-compounds was studied in each part of the plant after three months. After 83 days of culture small amounts of (14)C-compounds were found in the inflorescence (0.6 per thousand of the seed deposit) which were ...

Cytotoxicity of fipronil on mice liver cells

Microscopy Research and Technique, 2012
AbstractIn the present study, mice livers were examined following exposure to different doses of fipronil (15, 25, and 50 mg/kg). Histological and histochemical techniques were used to determine the cytotoxic potential of this compound and to assess the damage it caused to livers.
