Ecotoxocological effects of short-term exposure to a human pharmaceutical Verapamil in juvenile rainbow trout (Oncorhynchus mykiss)
Popis výsledku v původním jazyce
Verapamil (VRP) is a calcium channel blocker that is a highly prescribed compound and commonly present in aquatic environment, but the ecotoxicological effects of this pharmaceutical in fish have not been fully documented. In this study, the toxic effects of VRP were studied in juvenile rainbow trout, Oncorhynchus mykiss, by acute static bioassay. In the acute test, the median lethal concentration (LC50, 2.72 mg/L) was evaluated and the behavioral changes were obviously intensified with increasing VRP concentrations. Compared to the control, oxidative stress was observed in fish tissues with different levels after short-term exposure to sublethal concentrations (0.27 and 1.35 mg/L) of VRP. Activities of SOD and GPx in fish brain were induced at 0.27 mg/L VRP, but all the antioxidant enzymes (SOD, GPx and GR) in fish brain were decreased at 1.35 mg/L VRP. When compared to the control, all the antioxidant enzymes in gill were decreased in both treated groups, but there was no significant
