Dissipation Behavior and Dietary Risk of Etofenprox in Kale (Brassica oleracea) and Red Mustard Greens (Brassica juncea)

Year: 2025

Type: article

Abstract: ), leafy vegetables frequently reported to exceed residue limits in Korea. Field trials were conducted at three sites, and residues were analyzed using QuEChERS extraction followed by LC-MS/MS in accordance with MFDS and SANTE guidelines. The method validation parameters-specificity, linearity, limit of quantitation, accuracy, and precision-were within the acceptable criteria specified by the guidelines. The half-lives of etofenprox under greenhouse conditions were 2.2 days in kale and 3.1 days in red mustard greens, with dissipation rate constants of 0.3118 and 0.2232, respectively. Dietary risk assessment based on residue levels and consumption data confirmed that the %ADI values at the pre-harvest interval (PHI, 7 days) for were <1% the average consumer group and <4% for the high-intake group. Accordingly, the residue levels were considered safe, indicating that compliance with recommended application practices poses negligible health risk to consumers.
