摘要: Summary Heavy metal pollutions of aquatic ecosystems have already raised many concerns on organisms’health and survival especially their sperm. The effects a single sperm may be totally different from cocktail several metals because interactions, so the zinc, cadmium calcium trout carp sperms competition been examined by incubation concentrations cold heavy with radioactive competing metal. results showed that 65 Zn 109 Cd were not displaced even at 3000 ppm concentration but was equally well or decrease in pellet activity to 38 37% control values (0 concentration) concentration, respectively trout. Calcium replaced non-radioactive zinc as calcium. findings confirmed least part toxicity (especially cadmium) fish could due displacement essential Both similar pattern.
