Acute Toxicity of Silver Nanoparticles in Roach (Rutilus rutilus) and Goldfish (Carassius auratus)

Aquatic Ecosystem pollution, due to the diversity in users of aquatic environment has become to one of the serious challenges biotic community. Study of fish in aquatic ecosystems can be to lead better understand and more comprehensive ecological analysis about aquatic ecosystem. Heavy metals such as silver are one of these pollutants. They can accumulate in living tissue and lead to poisoning. Also, these compounds have the ability to pass along the food chain. For this purpose 147 were in a range of different concentrations of silver nanoparticles (0, 0.2, 1, 2, 6, 10 and 15 ml/L). The mortality of treatments was calculated at intervals of 24, 48, 72, 96 hours. The result of present study showed, between toxicity of silver nanoparticles for Roach (6.590 ml/l) compared with Goldfish (11.2 ml/l), there was significant difference (p<0.05). Also the results showed that silver nanoparticles are highly toxic for fish species.
