Unexpected Lack of Deleterious Effects of Uranium on Physiological Systems following a Chronic Oral Intake in Adult Rat
Figure 1
Effect of chronic ingestion of uranium on body weight, food, and drinking water intakes. Three parameters were recorded weekly in control group (open square) and in animals contaminated with uranium at 0.2, 2, 5, 10, 20, 40, or 120 mg/L (close circles). For standardization, drinking water consumption was expressed as mL per day per rat, food consumption was expressed as g per day per rat, and body weight was expressed by g. The indicated values are mean of animals for body weight and for daily intake of food and drinking water (two rats were housed per cage). For a clearer visualization, the SD of these values were not indicated in this figure: they were below 30% of mean values. There are no significant differences between control and contaminated groups.
