This study was conducted to investigate the residue amount of pesticide on the 41 medicinal herbs in Daejeon area. This study was carried out to monitor the current status of pesticide residues in commercial medicinal herbs for sale of food use in 2012. It was performed using GC/ECD, GC/NPD, HPLC to analyze pesticides residues. Residues of 283 pesticides were analyzed by a simultaneous multiresidue method in 41 medicinal herbs being on sale in Daejeon. The medicinal herbs detected pesticides in 10 of 41 cases, showed a detection rate of 24.39%. The medicinal herbs which exceed the maximum residue limit were five cases as Cnidii Rhizoma, Osterici Radix, Artemisiae Capillaris Herba, Zizyphi Fructus and Alismatis Rhizoma. And pesticide residue of Cnidii Rhizoma and Alismatis Rhizoma exceeds the limit standard presented in only medicine use of KFDA. The residual pesticides which had the high detection rate were Chlopyrifos, Tebuconazole and Endosulfan in the detection of medicinal herbs. For further research, standards of Pesticide Residues in medicinal herbs should be added and more research of pesticide residues in medicinal herbs required. And standards of pesticide residues in medicinal herbs should be applied equally as medicines and food.

This paper describes a shower type ultrasonic cleaning system using particle acceleration, developed for better effectiveness in washing out agricultural chemicals from fruits or vegetables, compared to the existing bath type ultrasonic cleaning system. The shower type system consists of a signal generator, a transducer, and a spouting nozzle, mainly. The system has been tested based on the method recommended by Korea Food and Drug Administration. It is found that shower type system shows better performance and cost-effectiveness than the bath type system that is commercially available .

The analysis method for qualitative analysis of the screening method that can be performed prior to the quantitative analysis of individual pesticide was reviewed in order to meet the safety standards that are being strengthened in the field of pesticide residue testing of herbal medicines. Among the residual pesticides presented in the Korean Pharmacopoeia, 56 pesticides, excluding 15 pesticides that need to be individually analyzed, were selected for analysis using QuEChERS preprocessing and GC-MS/MS, which are used in the existing agricultural products field. For each pesticide, the detection limit level of 0.001-0.005 mg/kg and the quantitative limit level of 0.002-0.017 mg/kg were confirmed. In the recovery test in which the standard was treated at a concentration of 0.02 mg/kg, it was confirmed that the proportion of pesticides satisfying the recovery of 70-120% was 85.7-96.4% for each herbal medicine, so it was confirmed that it was a level that could be reviewed by the screening method.

본 연구는 국내의 지리적표시제 등록특산물을 대상으로 농약 잔류실태를 조사하여 식품안전 정책수립의 기초자료와 잔류농약에 대한 식품의 안전성을 평가하고자, 지리적 표시 등록 특산물 17품목(마늘 1, 마늘 2, 마늘 3, 마늘 4,고추, 양파 1, 양파 2, 쌀 1, 쌀 2, 쌀 3, 참외, 사과, 밤, 대추, 황기, 표고버섯, 구기자)을 선정하여 잔류 실태를 조사하였다. 조사대상 농약으로는 다성분 분석농약 204종과 단성분 분석농약 5종(acephate, methamidophos, monocrotophos, omethoate, vamidothion)을 포함한 209종의 농약에 대해 잔류량을 조사하였으며, 분석장비로는 GC/MSMS, HPLC/UVD(PDA)와 GC/FPD를 사용하였다. 분석법방법으로는 식품공전의 83번 다성분분석법과 단성분분석법을 사용하였다. 분석결과 특산물 17품목 중 8품목(고추, 양파 1, 쌀 2, 쌀 3, 참외, 사과, 대추, 구기자)에서 잔류농약이 검출되었고, 검출시료수는 302건중 40건으로 13.2%의 잔류농약 검출율을 보였다. 그러나 모두 식품의 농약잔류허용기준 미만이었다.
