Figure 3: Toxicity of 81 nm silver nanoparticles (a) and silver ions (b) after 48 hours exposure to adult male zebrafish (Danio rerio) in a static renewal experiment. Black circles (●) represent the mean survival in percent after exposure to a given concentration ( 𝑛 = 1 0 ). Solid lines indicate the calculated lethality using probit analysis after exposure to silver nanoparticles and silver ions, respectively. Dashed lines indicate the 95% confidence intervals.
