Figure 3From: Sub-chronic toxicity study in rats orally exposed to nanostructured silicaSilica content in organs of animals orally exposed to SAS or NM-202 for 28 days. Silica content was measured by ICP-MS and presented in mg silica/kg tissue (mean ± standard error of the mean; n = 5). * Significant difference versus the control (p < 0.05).Back to article page
