QuEChERS-Based Method for the Determination of Fipronil in Protein Baits and Vespa velutina Larvae by HPLC-DAD and GC-MS

Separations
Protein baits containing fipronil as a biocide have shown their effectivity as a control method for Vespa velutina nigrithorax (Lepeletier, 1836) in apiaries. This biocide is not selective for Vespa velutina, so it is important to use the minimum dose to

In vitro inhibition of human CYP2D6 by the chiral pesticide fipronil and its metabolite fipronil sulfone: Prediction of pesticide-drug interactions

Toxicology Letters, 2019
Fipronil is a chiral insecticide employed worldwide in crops, control of public hygiene and control of veterinary pests. Humans can be exposed to fipronil through occupational, food, and environmental contamination. Therefore, the risk assessment of fipronil in humans is important to protect human health. Fipronil sulfone is the major metabolite formed

Multi‐Walled Carbon Nanotube‐Modified Carbon Paste Electrode for Fipronil Detection in Environmental Samples

Electroanalysis, Volume 37, Issue 7, July 2025.
A nanostructured carbon paste sensor modified with 20% multi‐walled carbon nanotubes (MWCNTs) was developed for the detection of Fipronil. The sensor showed enhanced electrochemical performance, with a limit of detection of 0.377 µmol L‐1. It demonstrated good stability, selectivity, and high recovery in water samples, highlighting the potential of ...

Thyroid-disrupting effects of exposure to fipronil and its metabolites from drinking water based on human thyroid follicular epithelial Nthy-ori 3‑1 cell lines [PDF]

, 2023
Fipronil is a broad-spectrum insecticide used for plants and poultry. Owing to its widespread use, fipronil and its metabolites (fipronil sulfone, fipronil desulfinyl, and fipronil sulfide), termed FPM, can be frequently detected in drinking water and ...

Association between pancreatic adenocarcinoma risk and concentration of organochlorine pesticides in adipose tissue and urine: A targeted‐screening analysis case‐control study (PESTIPAC)

United European Gastroenterology Journal, Volume 12, Issue 7, Page 951-959, September 2024.
Abstract Background Knowledge about environmental pancreatic adenocarcinoma (PA) risk factors, including pesticide exposure, remains limited. Organochlorine (OC) accumulates in adipose tissue and can help reflect long‐term exposure. Patients and Methods Age and body mass index (BMI) of patients with PA were matched with those undergoing a surgery for a

Potential role of veterinary flea products in widespread pesticide contamination of English rivers [PDF]

, 2021
Little is known about the environmental fate or impact of pesticides used to control companion animal parasites. Using data from the Environment Agency, we examined the occurrence of fipronil, fipronil metabolites and imidacloprid in 20 English rivers ...

Rapid Screening of 300 Pesticide Residues in Commercially Available Vegetable‐, Fruit‐, and Cereal‐Based Baby Foods by Using Amino‐Functionalized Multiwalled Carbon Nanotubes with QuEChERS and Gas Chromatography‐Electrostatic Field Orbitrap High‐Resolution Mass Spectrometry

Journal of Food Quality, Volume 2024, Issue 1, 2024.
A new method for screening 300 pesticide residues in fruit‐, vegetable‐, and cereal‐based baby foods by an improved QuEChERS purification method based on amino‐functionalized multiwalled carbon nanotubes (NH2‐MWCNTs) combined with gas chromatography‐electrostatic field orbitrap high‐resolution mass spectrometry (Orbitrap GC‐MS) was developed.
