Figure 3From: Toxicity of various silver nanoparticles compared to silver ions in Daphnia magnaSize distribution of particles based on cumulative frequency determined from transmission electron microscope data in: (A) nAg1 colloid, (B) nAg2 colloid, (C) and dry powder of nAg3. Statistically significant differences were found among particle size distributions (P < 0.001, nAg1 vs nAg2; P < 0.001, nAg1 vs nAg3; P < 0.001, nAg2 vs nAg3).Back to article page
