Figure 9From: Particle size dependent deposition and pulmonary inflammation after short-term inhalation of silver nanoparticlesGlutathione production in the lungs of rats. At 24 hours after exposure, the total glutathione production in the 15 nm silver nanoparticles exposed group was significantly elevated compared to the controls (p < 0.01) and the 410 nm silver particles exposed group (p < 0.05).Back to article page
