Photodegradation of organophosphorus pesticides in honey medium

Ecotoxicology and Environmental Safety, 2014
Honey can be polluted due to environmental pollution and misuse of beekeeping practices. In the present study, photodegradation experiments of organophosphorus pesticides (coumaphos, methyl parathion and fenitrothion) in honey medium were conducted using Atlas Suntest simulator CPS+ as a sunlight producer.

Plasma Pharmacokinetic Profile of Fipronil 1% Pour‐On in Cattle: Photodegradation and the Sustained Systemic Persistence of Fipronil Sulfone

Journal of Veterinary Pharmacology and Therapeutics, Volume 49, Issue 5, Page 515-524, September 2026.
ABSTRACT This study characterized the long‐term pharmacokinetic profile of a 1% fipronil pour‐on formulation in Nellore bulls under field conditions. Seventeen animals received a single topical dose (1 mg/kg), and plasma concentrations of fipronil and its metabolites (sulfone and desulfinyl) were monitored for 175 days using LC–MS/MS.
