Figure 2From: Distribution of silver in rats following 28 days of repeated oral exposure to silver nanoparticles or silver acetate Silver concentration in rat organs. Silver concentrations (mean ± 1s.d., N = 5-7) in rat organs after 28 days oral administration of silver nanoparticles and silver acetate. Statistically significant differences (p < 0.05) between the groups are marked with asterisks (*). Silver concentrations in the control animals were below the limit of detection.Back to article page
