Abstract
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.
