우엉 중 살충제 Tebufenozide의 경시적 잔류량과 식이 섭취 노출 위해 평가

초록

To evaluate the residue dissipation of tebufenozide in burdock, 8% wettable tebufenozide powder was applied, and the residue dissipation in the leaves and the roots was analyzed. Tebufenozide was not detected in the roots, whereas the initial residue was 8.63 mg kg⁻¹ in the leaves, and the dissipation half-life was 2.57 days. The initial residue in burdock leaves was approximately three times higher than that observed in treated aronia berries, which was attributed to the high surface area-to-weight ratio of burdock leaves. Based on the maximum residue limits (MRLs) registered in Korea, the theoretical maximum daily intake (TMDI) of tebufenozide was estimated to be 6.20 × 10⁻ mg kgb.w. 3 –1 day−1, corresponding to 31.0% of the acceptable daily intake (ADI) for the overall population. The 1-2-year-old age group was estimated to have the highest exposure, reaching 52.2% of the ADI. Furthermore, the TMDI for spinach, lettuce, and cabbage exceeded 20% of the ADI in each high food consumer (95th percentile) group.
