Abstract

Monitoring or follow-up surveying pesticide residues in agricultural commodities is the key to meet the international regulations and to enhance international competitiveness of Korean agricultural commodities. Six neonicotinoid insecticides, acctamiprid, clothianidin, dinotefuran, imidacloprid, thiacloprid, and thiamethoxam were monitored in 95 paprika samples collected from Gyeongnam area. Thc pesticide residues were extracted by EN 15662 buffer based on the QuEChERS method, clean-upped with dispersive solid-phase extraction method to remove interfering pigments, and analyzed using UPLC-MS/MS. The neonicotinoid pesticides were detected in 90.5% of the paprika samples. Two or more pesticides were detected in 82.3% of samples. Although detection frequencies were high, all samples complied with the maximum residue limits (MRLs) set by both the Korea Food and Drug Administration (KFDA) and Japanese Ministry of Health, Labour and Welfare.

본 연구는 QuEChERS 방법에 기초한 EN15662 buffer 및 dSPE, UPLC-MS/MS플 활용하여 경남지역에서 생산되는 대일 수출용 파프리카 내 neonicotinoid계 농약성분의 잔류성 실태 조사를 위하여 수행하였다. 6종의 neonicotinoid계 농약의 회수율 및 변이계수는 0.05 및 0.5 mg/kg 수준에서 각각 84.0~92.7(${\pm}0.0{\sim}3.8%$)과 95.1~98.9%(${\pm}0.9{\sim}5.2%$)로 나타났다. 분석에 사용된 95시료 중 90.3%에서 농약성분이 검출되었으며, 82.3%에서 2종이상의 농약성분이 검출되었다. 검출된 농약의 농도는 0.01~1.63 mg/kg으로 나타났고, 농약성분 중 dinotefuran 및 imidacloprid가 78.1 및 65.6%의 빈도를 보였다. 6종의 농약 중 thiacloprid가 8.3%로 분석된 농약 중 가장 낮은 빈도를 나타내었다. 그러나 검출된 농약의 경우 모두 한국 및 일본의 잔류허용기준을 초과하지 않는 것으로 나타나, 경남지역 생산 대일 수출용 파프리카의 경우 neonicotinoid 계 농약에 대한 사용이 안전한 수준으로 잘 관리되고 있음을 확인하였다.
