살균제 hexaculazole(1-(6-chloro-3-pyridytmethyl)-N-nitroimidazolidin-2-ylideneamine)의 잉어(Cyprinus carpio L.) 체내 장기중 분포를 구명하기 위하여 hexaconazole를 환경추정농도인 $0.32;mg;kg^{-1}$로 처리한 시험수에 잉어를 지수조건에서 4일간 노출시켰다. 수중의 hexaconazole은 잉어체내에 흡수되어 노출 2일차에 최대 흡수량을 나타내었으며, 다른 장기에 비해 쓸개에서 농도가 가장 높았다. 처리 후 2일차의 쓸개중hexaconazole의 농도는 간 중 잔류량의 약 25배, 신장 중 잔류량의 67배이었다. 이 결과를 근거로 할 때 잉어체내에 흡수된 hexaconazole의 주요 배설경로는 담도로 추정되었다.
In order to elucidate the behavior of the fungicide hexaconazole (1-(6-chloro-3-pyrldyhnethyl)N-nitroimidazolidin-2-ylideneamine) in carp (Cyprinus carpio L.), carps were exposed to [$^{14}C$]hexaconazole at a predicted environmental concentration (PEC) of 0.32 mg $L^{-1}$ for 4 days under static conditions. Hexaconazole in water was absorbed into carps to reach the maximum concentration 2 days after exposure. The amounts of the [$^{14}C$]hexaconazole and its metabolites absorbed in gall were much higher than those in the other organs and especially those in gall 2 days after exposure were 25 and 67 times higher than those in liver and kidney, respectively, strongly suggesting that biliary excretion involving enterohepatic recirculation could be an import route for the elimination of hexaconazole absorbed in carps.
