Translocated and retained fractions of intratracheally inhaled [48V]TiO2-NP in the organism. Retained fractions of intratracheally inhaled [48V]TiO2-NP investigated up to 28 days p.e. a: total translocation and blood; b: liver, spleen, and kidneys; c: heart, brain, and uterus (at 1 h p.e. heart and uterus fractions were < 0.00001); d: carcass, soft tissue, and skeleton. The mean IPLD in mass (number) of [48V]TiO2-NP of all five retention time points is 1.01 ± 0.55 μg (2.67 ± 1.16•1010 #). [48V]TiO2-NP retention is given as fractions of the initial peripheral lung dose (IPLD). Data in all panels correspond to the third line (all corr.) of each organ in Table 3. Mean ± SEM, n = 4 rats per time point. Statistical one-way ANOVA analysis with the post-hoc Bonferoni test in between all time points are given in the table below:
