Abstract

Jinpi(Aurantii nobilis Pericarpium) is one of the most important material of oriental herbal medicine which is made from the peel of mandarin by washing with hot water and drying. Pesticides have necessarily used for mandarin cultivation according to their preharvest intervals (PHIs) but their maximum residue limits (MRLs) and PHIs for Jinpi are not established yet. This study is to know residue amount of organophosphorus insecticides in Jinpi and to establish the MRLs and PHIs for fenitrothion and phenthoate in Jinpi. Fenitrothion was sprayed once, twice and three times with 7 days interval before harvest. Its residue amount ranged from 0.14 to 1.17 mg/kg in mandarin, 0.59 to 4.02 mg/kg in its peel and 1.66 to 22.38 mg/kg in Jinpi. In case of phenthoate, it was sprayed with 10 days interval for 10 days before harvest. Its residue amounts in mandarin, its peel, and Jinpi ranged from 0.16 to 0.65, 0.69 to 2.41 and 1.69 to 11.3 mg/kg, repectively. Proposed MRLs of fenitrothion and phenthoate for Jinpi are suggested to 22.39 and 11.30 mg/kg, respectively. So we recommend PHIs of the pesticides that fenitrothion can be sprayed 3 times 7 days before harvest and in case of phenthoate, sprayed 3 times 10 days before harvest.

한약재로 많이 사용되고 있는 진피에 대한 농약안전사용기준 설정과 잔류허용기준 설정을 위한 연구의 일환으로서 감귤에 fenitorthion와 phentoate를 살포하여 감귤전체, 감귤껍질, 감귤과육 그리고 껍질로부터 만든 진피를 대상으로 잔류량을 분석하였다. 현재 감귤에 설정되어 있는 안전사용기준에 따라 살포된 Fenitrothion의 최대잔류량은 진피에서 22.38 mg/kg, 감귤껍질에서 4.02 mg/kg, 감귤전체에서 1.17 mg/kg이었고 감귤과육에서 0.02 mg/kg으로 나타났다. 또한 phenthoate의 잔류량은 진피에서 11.30 mg/kg, 감귤껍질에서 2.41 mg/kg, 감귤전체에서 0.65 mg/kg이었고, 감귤과육에서 0.03 mg/kg으로 나타났다. 감귤 껍질부터 진피를 만들때의 가공계수로써 fenitrothion은 2.53~5.57이고 phenthoate는 1.60~4.69이었다. 진피에 대하여 제안 할 수 있는 잔류허용기준은 fenitrothion의 경우 22.39mg/kg, phenthoate의 경우 잠정 MRL이 11.30 mg/kg으로 나타났다. 이 잠정 MRL을 바탕으로 진피 생산을 위한 안전사용기준을 제시하면 fenitrothion의 경우 수확 7일전 3회 그리고 phenthoate는 수확 10일전 3회로 나타나 현재의 감귤 재배시의 안전사용기준가 동일하게 나타났다.
