Each bar represents the mean ± standard deviation of three replicates (n = 8). Bars with different letters are significantly different Figure 3 Glutathione peroxidase activity in the soft tissue of T. fuscatus exposed to various sublethal concentrations of hexavalent chromium. Each bar represents the mean ± standard deviation of three replicates (n = 8). Bars with different letters are significantly different The concentration of reduced glutathione (GSH) decreased significantly in the exposed groups compared to the control (F3,28 = 34.16; p ˂ 0.0001). However, the levels of GSH were not significantly different between the control and the animals exposed to 0.42 mg/L Cr6+ (Figure 4).
