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.

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.

A Polyvinyl Alcohol Coated Copper Foam Solid Phase Extractor for Determining Fipronil and Fipronil Sulfone

ECS Transactions, 2022
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 ...

A first approach using micellar electrokinetic capillary chromatography for the determination of fipronil and fipronil‐sulfone in eggs

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.

Determination of Fipronil and Fipronil-Sulfone in Surface Waters of the Guandu River Basin by High-Performance Liquid Chromatography with Mass Spectrometry

Bulletin of Environmental Contamination and Toxicology, 2021
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.

Distribution of fipronil in humans, and adverse health outcomes of in utero fipronil sulfone exposure in newborns

International Journal of Hygiene and Environmental Health, 2019
Fipronil is a highly effective insecticide with extensive usages; however, its distribution and toxic/health effects in the human population after chronic exposure have not yet been clearly identified. Our objectives were to determine the levels of serum fipronil and fipronil sulfone, a primary fipronil metabolite, in a general and sensitive human ...

A novel electrochemical sensor for the detection of fipronil and its toxic metabolite fipronil sulfone using TiO2-polytriazine imide submicrostructured composite as an efficient electrocatalyst

Talanta, 2022
For the first time, a simple and sensitive electrochemical sensor based on a screen printed electrode (SPE) modified with titanium dioxide (TiO2) and polytriazine imide submicrostructured composite (TiO2-PTI) has been developed for the simultaneous detection of fipronil (FIP) and its toxic metabolite fipronil sulfone (FIP-S).
