Uranium LIII-edge XANES spectra of rat kidney by bulk kidney measurements. (a) Renal section from a prepubartal rat at the middle phase after uranium exposure at the high dose (day 3 post-injection, 2 mg kg−1 body weight). (b–d) Renal section from an adult rat at the initial phase at the low dose [(b) day 1 post-injection, 0.5 mg kg−1 body weight], the middle phase [(c) day 3 post-injection] and the late phase [(d) day 15 post-injection] at the high dose (2 mg kg−1 body weight). The mean renal uranium concentrations of (a), (b), (c) and (d) were 10.2 µg g−1, 12.9 µg g−1, 34.4 µg g−1 and 17.5 µg g−1, respectively. |
