Abstract

This study was carried out to investigate the degradation of six residual pesticides (${\alpha}$- and ${\beta}$-Endosulfan, Cypermethrin, Fenitrothion, Hexaconazole, EPN) in red pepper powder after ultraviolet (UV) irradiation. The residual ratio of pesticides after 365 nm irradiation which distance is 20 cm and irradiation time is 5 minutes were 73.4, 69.6, 60.8, 92.7, 73.8 and 90.5% in ${\alpha}$-Endosulfan, ${\beta}$-Endosulfan, Cypermethrin, Fenitrothion, Hexaconazole and EPN, respectively. The residual ratio of pesticides after 254 nm irradiation which distance is 5 cm and irradiation time is 36 hours were 74.6, 64.5, 71.1, 79.1, 79.4 and 64.7% in ${\alpha}$-Endosulfan, ${\beta}$-Endosulfan, Cypermethrin, Fenitrothion, Hexaconazole and EPN, respectively.

고춧가루에 잔류되어 검출 빈도가 높은 농약인 Endosulfan(${\alpha}$-, ${\beta}$-체) Cypermethrin, Fenitrothion, Hexaconazole, EPN을 고춧가루에 인위적으로 오염시킨 뒤 365, 254 nm 파장에서 조사거리와 조사시간을 달리하여 잔존률을 조사하여 자외선 조사로 인한 농약의 제거효과를 알아보았다. 365 nm의 경우 조사거리 20 cm, 조사시간이 5분일 때 ${\alpha}$-Endosulfan 73.4%, ${\beta}$-Endosulfan 69.6%, Cypermethrin 60.8%, Fenitrothion 92.7%, Hexaconazole 73.8%, EPN 90.5%의 잔존률을 나타내었으며, 254 nm의 경우 조사거리 5 cm, 조사시간 36시간 일 때 ${\alpha}$-Endosulfan 74.6%, ${\beta}$-Endosulfan 64.5%, Cypermethrin 71.1%, Fenitrothion 79.1%, Hexaconazole 79.4%, EPN 64.7%의 잔존률을 나타냈다.
