Incorporation of uranium. II. Distribution of uranium absorbed through the lungs and the skin.
In experiments on mice, rabbits, and piglets the distribution of uranium was studied at different times after exposure. Uranium was administered by inhalation (mice) and through the skin (rabbits and piglets). These investigations show that the uptakes of uranium in different organs of the three species are highly dependent on the amounts administered. There seems to be a saturation effect in t...
متن کاملDistribution of uranium in human bones.
Uranium and calcium contents in human bones (skull, rib and femur) were determined by the fission track method and the inductively coupled plasma-atomic emission spectroscopic method (ICP-AES), respectively. The U/Ca concentration ratio in the bones was found to decrease in the order of rib greater than femur greater than skull, which is in accordance with the decreasing order of the mean annua...
متن کاملUranium behaviour in the baboon after the deposition of a ceramic form of uranium dioxide and uranium octoxide in the lungs : implications for human exposure
U 0 2 and U 3 0 8 were inhaled by baboons in amounts such that the mass concentrat ions in the lungs were between about 3 and 20, and 1 and 7.4 t imes respectively those calculated in human lungs after exposure to 1 ALI of the compounds . The results show that 1 year later : 1) the initial lung deposits of uranium retained in the chest are greater for U 0 2 than for U 3 0 8 ; 2) the ratios of t...
متن کاملDistribution of uranium in rats implanted with depleted uranium pellets.
During the Persian Gulf War, soldiers were injured with depleted uranium (DU) fragments. To assess the potential health risks associated with chronic exposure to DU, Sprague Dawley rats were surgically implanted with DU pellets at 3 dose levels (low, medium and high). Biologically inert tantalum (Ta) pellets were used as controls. At 1 day and 6, 12, and 18 months after implantation, the rats w...
متن کاملPost monsoon spatial distribution of uranium in water of Alaknanda and Ganges river
Background: Uranium poses both chemical and radiological hazard to the living system. Drinking water from river is one of the major sources of uranium intake. Dissolution of minerals, washout from rain water, rock-water interaction, agricultural run off, and industrial disposals are some of the sources of uranium in river water system. Present study was aimed to determine the uranium in the wat...
