The toxicity of several waterborne heavy metals to aquatic organisms is associated with oxidative damages due to the formation of reactive oxygen species (ROS). In the present work, the reproductive toxicity of the heavy metal cadmium was tested with the sperm of freshwater crab. The crabs were exposed to sublethal concentrations of 0, 7.25, 14.5, 29, 58 and 116 mg/L of Cd²⁺ for 3, 5 and 7 d. Cd²⁺ accumulation, ROS formation, and the total antioxidant capacity (TAC) in Sinopotamon henanense… CONTINUE READING
