본 연구는 경기도에 유통되는 기능성 쌀을 대상으로 농약 및 이산화황의 잔류실태를 조사하고 위해성평가를 실시하였다. 2016년 2월부터 10월까지 대형마트 및 재래시 장에서 유통되는 기능성 쌀 91건을 수거하여 수행하였다. GC/ECD, GC/NPD, GC/TOF/MS, LC/PDA, LC/FLD를 이 용한 다종농약다성분 분석법으로 220종의 잔류농약검사를 실시한 결과 3건(3.3%)에서 2종의 농약성분이 검출되었다. 검출된 농약은 살균제 농약인 propiconazole과 살균제 및 식물생장조절제 농약인 isoprothiolane이며, 검출수준은 0.0340~0.0566 mg/kg으로 MRL (Maximum Residues Limits) 대비 각각 34%, 2.8% 이하로 검출되었다. Monier-Williams 변법을 이용하여 이산화황(sulfur dioxide)을 분석한 결과 91건의 시료 모두 불검출이었다. 농약 검출량을 바탕으로 일일섭취추정량(EDI)과 일일섭취허용량(ADI)을 이용하여 위해성평가를 한 결과 %ADI (Hazard Index)는 0.24~ 1.25%로 안전한 수준이었다.

This study was conducted to monitor the current status of pesticide residues and sulfur dioxide in a total of 91 functional rice products from February to October 2016. Multi class pesticide multiresidue methods of 220 pesticides was performed by the GC/ECD, GC/NPD, GC/TOF/MS, LC/PDA, and LC/FLD. As a result of analysis, the pesticides were detected in 3 samples, representing a detection rate of 3.3%. The kind of pesticides was propiconazole and isoprothiolane used for germicide in agriculture or plant growth regulator purposes. The detected levels were 0.0340~0.0566 mg/kg, which were under the MRL (Maximum Residues Limits). The contents of sulfur dioxide in 91 samples by the Monier-Williams method were not detected. Risk assessment of pesticides evaluated using human health exposure with the ratio of EDI (Estimated daily intake) to ADI (Acceptable daily intake). %ADI (the ratios of EDI to ADI) were 0.24~1.25% with safety level.
