Toxicity of Nickel to Fresh Water Fish, Channa
نویسنده
چکیده
Heavy metals are considered as the most important pollutants of the aquatic environment. In the present study, acute toxicity test was used for the determination of lethal toxicity of Nickel in adult fish, Channa gachua as the test organism. Toxicity test is most reliable for accessing the adverse effect of pollutants on aquatic life. The LC50 values were determined and observed that the values decreased with increase in the exposure period of the fish. The present investigation revealed that the mortality of test fish were dose and time dependent and might be due to bio concentration of these metals in tissues due to continuous exposure leading to the death of the fish.
