본 연구를 통해 신규농약인 isotianil의 쌀에 대한 잔류허용기준과, 기준이 확대되는 21종 농약에 대해 26개의 농약잔류허용기준을 제시하였다. Iisotianil의 쌀에 대한 MRL은 0.1 mg/kg으로 설정하였고, ADI대비 TMDI의 비율 1.54%로 안전한 수준으로 판단된다. 기준이 확대되는 21종의 농약의 경우 dinotefuran, idoxacarb, trifumizole을 제외한 나머지 농약은 ADI대비 TMDI의 비율이 50% 미만으로 안전성에 문제가 없는 수준으로 판단된다. Trifumizole은 재평가를 통해 미등록된 작물의 기준을 폐지하면, 현재의 ADI대비 TMDI 비율 절반 수준인 30% 미만으로 감소될 것으로 예측된다.
BACKGROUND: Food Sanitary Act establishes Maximum Residue Limits (MRLs) of pesticides in food that are newly registered and used per each quarter, as stipulated by Agro-chemical Control Act. Current Food Code contains the MRLs for a total of 418 pesticides in 184 food types. METHODS AND RESULTS: National MRLs for pesticides have been established by based on scientific data of good agricultural practice, acceptable daily intake (ADI), food intake, average body weight and others. MRLs for pesticides are generally set under the principle that theoretical maximum daily intake (TMDI) are always below ADI. As results, 27 MRLs in agricultural products were newly proposed for 22 pesticides (fungicide: azoxystrobin, fludioxonil, fluquinconazole, flusilazole, iprovalicarb, kresoxim-methyl, mandipropamid, metconazole, pyraclostrobin, tebuconazole, triflumizole, etc., Insecticide: dinotefuran, flubendiamide, indoxacarb, cyhalothrin, spinetoram, thiacloprid, thiamethoxam, metaflumizone, etc., Acaricide(miticide): cyenopyrafen, lufenuron) in 2010. CONCLUSION(s): There is no intake concerns for establishment of pesticide MRLs on foods in this time. Because the ratio of theoretical maximum daily intake (TMDI) are set below that of ADI.
