Comparison of Toxicity of Silver Nanoparticles in Three fish species: Cyprinus carpio, Ctenopharyngodon idella and Hypophthamichthys molitrix
Message:
Abstract:
Silver compounds have long been as disinfectant and can be used in aquaticulture. In this study the toxicity effects (LC50)) of two Silver nanoparticles (L2000 and Ls2000) in three species were calculated. Each species were challenged with 6- 8 serial dilutions of Nanoparticles and daily mortality recorded for 96 hours. Results showed that LC50 96h of Nanosilver in Cyprinus carpio, Ctenopharyngodon idella and Hypophthamichthys molitrix ofSilver nanoparticles (L2000 ) were 0.099, 0.076 and 0.238 mg/l and LC50 96h of Nanosilver in three species of Cyprinid fishes Silver nanoparticles (Ls2000 ) were 0.058, 0.057 and 0.094 mg/l and LC99, 96h of Nanosilver in three species of Cyprinid fishes Silver nanoparticles (L2000 ) were 0.246, 0.135 and 0.658 mg/l and for Silver nanoparticles (Ls2000 ) were 0.092, 0.096 and 0.161 mg/l ,There was Significant difference among toxicity rate of two silver nanoparticles in three species of Cyprinid fishes (P<0.05). Respectively, versus The MAC of two Silver nanoparticles (L2000 and Ls2000) toxicity in Cyprinus carpio were 0.010 and 0.006 and The MAC of two Silver nanoparticles toxicity in Ctenopharyngodon idella were 0.008 and 0/006 and in Hypophthamichthys molitrix were 0/024 and 0/009. According to the results of this study it can be conducted three species of fishes is highly susceptible to L-2000 and Ls-2000, but Ls-200 is more toxic.
