This study investigated the dissipation kinetics of fluxapyroxad in apples, the effect of yeast-based biological treatment, and dietary exposure assessment for adults and children. Gas chromatography with electron capture detection (GC-ECD) analyzed fluxapyroxad residues using the QuEChERS method. Dissipation half-lives were 8.9 and 9.0 days for Gala and Idared apple varieties, respectively. Yeast treatment (Myco-Sin) reduced fluxapyroxad levels by 59.9% (Gala) and 43.8% (Idared). Dietary risk assessment showed acceptable safety levels (below 9.8% for children and 1.9% for adults).
