Fig. 3From: Quantitative biokinetics over a 28 day period of freshly generated, pristine, 20 nm silver nanoparticle aerosols in healthy adult rats after a single 1½-hour inhalation exposureDaily fecal excretion after intratracheal inhalation of [105Ag]AgNP. Panel a: Fecal excretion rates of [105Ag]Ag activity after intratracheal inhalation of [105Ag]AgNP per lung dose (ILD); y-axis log scale. Data of the groups of rats dissected after 24 h, 7 days and 28 days are presented. For the 28 days group, integral fecal samples over 3–4 days are divided by the number of sampling days and associated with the mean day of the sample interval. Panel b: cumulative fecal excretion of [105Ag]Ag activity per ILD (y-axis lin scale). Mean ± SEM, n = 4 rats per time pointBack to article page
