Abstract

Author(s): M. David* and RM. Kartheek

Sodium cyanide which has a wide range of applications in mining industries also has harmful effects on various organisms. The cyanide utilized by mining industries is let off into streams seriously compromises with the survival of the fish population. In the present study an attempt was made to analyze the toxicity of sodium cyanide to the kidney of freshwater fish Cyprinus carpioby histopathological aids. The results obtained suggested that sodium cyanide at a concentration of 0.2mg/L (1/5thof LC50) can impact the fish kidney in a catastrophic manner and cause the variation in histoarchitechture of kidney. Based on the outcome of the present study, it is therefore suggested that appropriate measures be taken for detoxification of sodium cyanide before it is discharged into streams, as it can compromise the survival of aquatic habitat consequently resulting in the disturbances of aquatic ecosystem.
