Abstract
시설재배 풋고추 및 착색단고추의 재배과정 중 살포되는 chlorpyrifos의 잔류특성을 밝히고자 재배시기 및 약제살포 방법별 잔류량을 조사, 평가하였다. 고추의 재배시기별 열매 중 chlorpyrifos 잔류는 하절기(6~7월)에 비해 동절기(2~3월)에 1.5~2.7배 높게 검출되었다. 동절기 재배중인 풋고추와 착색단고추에 7일 간격 3회 약제 살포 후 1~10일 동안의 잔류량을 비교하였다. 고추 중 잔류량은 1일차 2.070에서 10일차 <TEX>$0.929mg\;kg^{-1}$</TEX>로 감소하였으며, 착색 단고추는 1일차 0.302에서 10일차 <TEX>$0.291mg\;kg^{-1}$</TEX>으로 감소하여 두 농산물간의 농약잔류량은 6.9~3.2배 차이를 보였다. 착색단고추에 약제를 3일과 7일 간격으로 3회 살포 후 1~10일 동안의 농약잔류량은 각각 0.498~0.291, <TEX>$0.302{\sim}0.267mg\;kg^{-1}$</TEX> 범위였다. 착색단고추에 살포농도를 표준량과 배량으로 처리하였을 때 열매 중 농약의 잔류농도는 배량 처리시 2.5배 정도 높았으며, 살포 물량을 달리 했을 때의 영향은 거의 없었다. The characteristics of chlorpyrifos was studied to clarify the effect of the cultivation season, spray intervals, spray volume and concentration on residues in chilli and sweet peppers cultivated under greenhouse condition. Residue levels of chlorpyrifos detected in chilli pepper fruit cultivated were 1.5 to 2.7 times higher in winter(February-March) than those in summer(June-July). During winter season residue levels of chlorpyrifos in chilli peppers were 6.9~3.2 times higher than those in sweet peppers for 10 days after 3 times application with 7 days interval. Residue levels in chilli pepper were from 2.070 mg/kg at 1 day to 0.929 mg/kg at 10 day, while those in sweet pepper were from 0.302 mg/kg to 0.291 mg/kg. Residue levels in sweet pepper to which are 3 times applied with 7 days interval were from 0.302 mg/kg at 1 day to 0.291 mg/kg at 7 day, and the residue levels in sweet pepper which are 3 times applied with 3 days interval were from 0.498 mg/kg at 1 day to 0.470 mg/kg at 7 day. Residue levels of chlorpyrifos in the sweet peppers applied by double concentration were 2.5 times higher than those sprayed by normal standard amounts diluted in double volume.
