노니 중 살충제 Acetamiprid, Afidopyropen, Emamectin benzoate의 잔류특성 및 위해성 평가

Abstract

This study aimed to investigate the residual characteristics and safety assessment of acetamiprid, afidopyropen, and emamectin benzoate in Noni under greenhouse conditions. The Noni samples were treated with the pesticides twice at 7-day intervals and harvested on days 0, 7, 14, and 21 after the last treatment. The average recoveries of all pesticides ranged from 73.2% to 99.1%, which was sufficient for residue analysis. The residual amounts of acetamiprid, afidopyropen, and emamectin benzoate in noni were 0.09-0.15 mg/kg, 0.05-0.07 mg/kg, 0.01-0.03 mg/kg, respectively, indicating a tendency for dissipation over time. The biological half-lives of acetamiprid, afidopyropen, and emamectin benzoate were 28.6, 34.6, and 8.8 days, respectively. The %ADI values for these pesticides were below 1%, indicating a safe level of residue. These results provide important fundamental data for the future establishment of PHI (Pre-Harvest Interval) and MRL (Maximum Residue Limit) for Noni.
