2,4-Dinitrotoluene (2, 4-DNT) is a common environmental pollutant. The toxic effect on mammals of 2,4-DNT has been well studied, but its toxicity on aquatic organisms is little known. In this study, 126 healthy female zebrafish (Danio rerio) were exposed to different concentrations of 2,4-DNT (0, 2, 4, 8, 12 and 16mg/L) to determine 96-h semi-lethal concentrations (LC50). And then, 90 female zebrafish were exposed to 0, 2, 4 and 8mg/L 2,4-DNT for 5days to study liver toxicity. Exposed zebrafish developed hypoxia features, such as floating head ...
