Abstract

The post-harvest concentration change of four kind of pesticides, captan, chlorpyrifos, methidathion and kresoxim-methyl was investigated with the storage period for the import fruit. Then the post-harvest concentration was set to 1000, 250, 400 and 157 $mgkg^{-1}$ for captan, chlorpyrifos, methidathion and kresoxim-methyl respectively. In case of captan, 0.9-12.5 $mgkg^{-1}$ in total fruit base and ND-0.23 $mgkg^{-1}$ in the sarcocarp were measured after atomization and 0.7-3.2 $mgkg^{-1}$ in total fruit base and ND-0.67 $mgkg^{-1}$ in the sarcocarp were measured after four week. For chlopyrifos, menthidathion, and kresoxim-methyl 0.4-2.2, 0.7-3.1 and 1.3-2.1 $mgkg^{-1}$ in total fruit base and ND-0.32, ND-0.05 and ND-0.16 $mgkg^{-1}$ in the sarcocarp were measured after atomization respectively. After four week 0.3-0.9, 0.4-2.0 and 1.3-1.8 $mgkg^{-1}$ in total fruit base and ND-0.02, ND-0.05 and ND-0.15 $mgkg^{-1}$ in the sarcocarp were investigated for other three pesticides. The concentration decreasing ratio of pesticides was largest for captan, 52% and other components were in order of chlopyrifos, menthidathion, and kresoxim-methy, 47, 41, 11% each other.

수입과일을 대상으로 captan, chlorpyrifos, methidathion 및 kresoxim-methyl 을 각각 1000, 250, 400 및 157 $mgkg^{-1}$ 농도로 수확 후 처리 하여 저장 기간에 따른 경시적 변화를 관찰한 결과 captan은 처리 직후 과일 전체에서 0.9-12.5 $mgkg^{-1}$, 과육에서 ND-0.23 $mgkg^{-1}$ 으로 조사 되었으며, 4주 후에는 과일 전체에서 0.7-3.2 $mgkg^{-1}$, 과육에서 ND-0.67 $mgkg^{-1}$으로 조사되었다. chlorpyrifos은 처리 직후 과일 전체에서 0.4-2.2 $mgkg^{-1}$, 과육에서 ND-0.32 $mgkg^{-1}$으로 조사 되었고, 4주 후에는 과일전체에서 0.3-0.9 $mgkg^{-1}$, 과육에서 ND-0.02 $mgkg^{-1}$으로 조사 되었다. methidathion은 처리 직후 과일 전체에서 0.7-3.1 $mgkg^{-1}$, 과육에서 ND-0.05 $mgkg^{-1}$으로 조사되었고, 4주 후에는 과일 전체에서 0.4-2.0 $mgkg^{-1}$, 과육에서 ND-0.05 $mgkg^{-1}$으로 조사 되었다. kresoxim-methyl은 처리 직후 과일 전체에서 1.3-2.1 $mgkg^{-1}$, 과육에서 ND-0.16 $mgkg^{-1}$으로 조사 되었고, 4주 후에는 과일 전체에서 1.3-1.8 $mgkg^{-1}$, 과육에서 ND-0.15 $mgkg^{-1}$으로 조사 되었다. 농약처리 4주 후 농도의 감소율은 captan이 52%로 가장 높았으며 다음으로 chlorpyrifos, methidathion 및 kresoximmethyl이 각각 47, 41 및 11% 순으로 조사 되었다.
