Compare the Toxicity of Silver Nanoparticles Produced by Biological and Chemical Methods on Artemia franciscana in Naupliar and Adult Stages

In this study, the toxicity of silver nanoparticles (AgNPs) and the difference in sensitivities in naupliar and adult stages of Artemia fransiscana, were evaluated to absorption of chemical and biosynthesized by the seaweed Ulva flexuosa, forms of AgNPs. The A. nauplii and adult were exposed to additive serial concentration of biosynthetic and chemical AgNPs. Mortality in each group at the times of 12, 24, 36 and 48 h after exposure to AgNPs were recorded and analyzed via Probit software. The toxicity of these two types of AgNPs on A. nauplii and adult increased in a dose-dependent manner, but also their toxicity increased along with duration of exposure time. The toxicity of nanoparticles were significantly different (P
