Biochemical responses in gills of rainbow trout exposed to propiconazole

Popis výsledku v původním jazyce

The aim of this study is to investigate the toxic effect of PCZ, a triazole fungicide commonly present in surface and groundwater, on the ROS defense system and Na+-K+-ATPase in gills of rainbow trout exposed to sublethal concentrations (0.2, 50 and 500mýg L-1) for 7, 20 and 30 days. After prolonged exposure of PCZ at higher test concentrations (50 and 500 mýg L-1), oxidative stress was apparent as reflected by the significant higher ROS levels in fish gill, as well as the significant inhibition of SODand CAT activities. In addition, Na+-K+-ATPase activities were significantly lower than those of the control with increasing PCZ concentration and prolonged exposure period. The results of this study indicate that chronic exposure to PCZ has altered multiple physiological indices in fish gill; however, before these parameters are used as unique biomarkers formonitoring residual pharmaceuticals in aquatic environments, more detailed laboratory experiments need to be performed.
