Fig. 4From: Kinetics and dissolution of intratracheally administered nickel oxide nanomaterials in ratsDose-dependent clearance rate constants (a) and lung-to-lymph nodes translocation rate constants (b). Broken line in (a) shows the 2-month half-life (0.0115/day). The rate constants of seven types of TiO2 from a previous study [9] are also described in this figureBack to article page
