A comprehensive review of environmental fate and degradation of fipronil and its toxic metabolites

Environmental Research, 2021
The use of pesticides to increase crop production has become one of the inevitable components of modern agriculture. Fipronil, a phenylpyrazoles insecticide, is one of the most widely used, systemic, broad-spectrum insecticides.

CYP450-Dependent Biotransformation of the Insecticide Fipronil into Fipronil Sulfone Can Mediate Fipronil-Induced Thyroid Disruption in Rats [PDF]

Toxicological Sciences, 2012
In rats, the widely used insecticide fipronil increases the clearance of thyroxine (T(4)). This effect is associated with a high plasma concentration of fipronil sulfone, the fipronil main metabolite in several species including rats and humans. In sheep, following fipronil treatment, fipronil sulfone plasma concentration and thyroid disruption are ...

A highly selective and sensitive europium-organic framework sensor for the fluorescence detection of fipronil in tea.

Food Chemistry, 2023
A europium-based metal organic framework (Eu-TFPA-MOF) was used for the fluorescence detection of fipronil in green tea and oolong tea for the first time.

Fate and toxicity of 2,4-D and fipronil in mesocosm systems.

Chemosphere, 2023
2,4-D and fipronil are among Brazil's most used pesticides. The presence of these substances in surface waters is a concern for aquatic ecosystem health.

Switchable aptamer-fueled colorimetric sensing toward agricultural fipronil exposure sensitized with affiliative metal-organic framework.

Food Chemistry, 2022
Persistent usage of pesticides in agriculture has posed serious damage to overall ecosystem and human health, and thereby it is imperative to develop sensitive and efficient tools to evaluate residual pesticides in food and environmental setting. Herein,

Toxicity assessment of carvacrol and its acetylated derivative in early staged zebrafish (Danio rerio): Safer alternatives to fipronil-based pesticides?

Comparative biochemistry and physiology. Toxicology & pharmacology : CBP, 2023
Fipronil is a broad-spectrum pesticide presenting high acute toxicity to non-target organisms, particularly to aquatic species. Natural compounds stand out as promising alternatives to the use of synthetic pesticides such as fipronil.

Realistic exposure to fipronil, 2,4-D, vinasse and their mixtures impair larval amphibian physiology.

Environmental Pollution, 2022
Expansion of sugarcane crops may have contributed to the increased contamination of native habitats in Brazil. Several species of amphibians inhabit ponds formed in flooded farmlands, where pesticide concentrations are usually high.

Electrochemical oxidation of fipronil pesticide is effective under environmental relevant concentrations.

Chemosphere, 2022
Pesticide overuse has posed a threat to agricultural community as well as for the environment. In order to treat this pollution at its source, decentralized and selective technologies such as electrochemical processes appear especially relevant to avoid ...

Combined metabolic and target-site resistance mechanisms confer fipronil and deltamethrin resistance in field-collected German cockroaches (Blattodea: Ectobiidae).

Pesticide Biochemistry and Physiology, 2022
Despite insecticide resistance issues, pyrethroids and fipronil have continued to be used extensively to control the German cockroach, Blattella germanica (L.) (Blattodea: Ectobiidae) for more than two decades.
