Toxicity Assay on Platinum Nano Particles to Fresh Water Fish ?Cirrhinus Mrigala?
Dr. Y. Thangam  | C. Veeramani
Abstract: In the present study platinum nanoparticles were exposed to freshwater fish Cirrhinus mrigala and the toxicity (acute and sublethal) assay were investigated. The Lethal concentration value were noted. The median lethal concentration (LC 50) of platinum to an Indian major carp Cirrhinus mrigala for 24 hours and 96 hours were found to be 12 mg/L and 6 mg/L. The main toxic action of platinum on aquatic animals during acute and sublethal toxicity leads to mortality due to metal accumulation in fishes through the gills. During acute treatment of platinum, the fish Cirrhinus mrigala showed behavioral changes such as loss of balance, restlessness, abnormal swimming. During sublethal treatment of platinum, the fish Cirrhinus mrigala showed the changes such as the gulping of air, opercular movement, erratic jumping.
