초록

농약 남용에 의한 잔류 농약은 환경 및 소비자의 건강에 영향을 미칠 수 있으며 , 이에 따라 제외국은 농약 잔류허용기준 (MRL)을 설정하고 있다 . 귀리에 kresoxim-methyl과 pyraclostrobin 처리 후 잔류 특성과 위해성 평가를 실시하였다 . 두 농약의 잔류량은 알곡의 경우 각각 < 0.01 mg/kg, 0.02~0.08 mg/kg, 짚의 경우 각각 0.30~0.92 mg/ kg, 2.96~13.36 mg/kg로 확인되었다 . 귀리 알곡과 짚에서 잔류한 pyraclostrobin에 대해 위해성이 가장 높은 시나리 오(99퍼센타일 )로 평가한 결과 , Hazard index (HI) 값은 0.00435 및 0.00004로 위해성이 낮았다 (HI < 1). 실제 농업 환경 내 섭취시나리오를 고려하여 최종 약제 살포 후 14, 21, 30일 이후 처리구를 대상으로 위해성 평가한 결과 , 수 확 당일에 비해 농약 노출 위해성이 점차적으로 감소하는 것을 확인하였다 (알곡 : kresoxim-methyl, pyraclostrobin HI = 00004, 0.00109~0.00435; 짚: kresoxim-methyl, pyraclostrobin HI = 0.00028~0.00076, 0.03883~0.09581).

The overuse of pesticides can lead to residual problems, posing significant risks to both the environment and consumer health. Consequently, many countries have implemented Maximum Residue Limits (MRLs) for pesticide residues in agricultural products. This study evaluates the residue characteristics and conducts a risk assessment of strobilurin-based pesticides, kresoxim-methyl and pyraclostrobin, in Avena sativa L. (oats) grain and straw. Residue analysis revealed that the level of kresoxim-methyl in oat grains were < 0.01 mg/kg, while for pyraclostrobin the residue levels ranged from 0.02~0.08 mg/kg. In straw, the kresoxim-methyl residue levels were between 0.30~0.92 mg/kg. and for pyraclostrobin it ranged from 2.96~13.36 mg/kg. A risk assessment for pyraclostrobin residues in oats using the 99th percentile exposure as the highest risk scenario yielded Hazard Index (HI) values of 0.00435 and 0.00004, indicating a low risk (HI < 1). [Editor’s note: specifying the previous two value are for straw or grain would lead to better understanding] Furthermore, considering realistic agricultural exposure scenarios, risk assessment conducted on pesticide-treated plots at 14, 21, and 30 days after the final application showed a progressive reduction in pesticide exposure risk compared to the day of harvest. (For grain, the HI value was 0.00004 for kresoxim- methyl and 0.00109~0.00435 for pyraclostrobin, whereas for straw, the HI value obtained was 0.00028~ 0.00076 for kresoxim-methyl and 0.03883~0.09581 for pyraclostrobin).
