Restricted to heavy water (99.8%), rats drank it freely for the first day, then they drank progressively less and died within 14 days. When given a choice between distilled water and heavy water (99.8%) rats avoided heavy water partly by virtue of some deleterious effects of heavy water and partly by virtue of a faint smell of heavy water with which the untoward effects could be associated. Rats did not taste heavy water. Whether a higher viscosity of heavy water plays any part could not be determined. Apparently the low intensity of any untoward effects of heavy water and the faintness of its smell could explain the erratic variability of the reactions of rats to heavy water that put it in a different category from other substances tested so far.
仅限于重水(99.8%),大鼠在第一天可以自由饮用,之后它们的饮用量逐渐减少,并在14天内死亡。当在蒸馏水和重水(99.8%)之间进行选择时,大鼠部分地由于重水的一些有害影响,部分地由于重水微弱的气味(这种气味可能与不良影响有关)而避开重水。大鼠没有尝过重水。重水较高的粘度是否起作用尚无法确定。显然,重水任何不良影响的低强度及其气味的微弱可以解释大鼠对重水反应的不稳定变化,这使其与迄今为止测试的其他物质属于不同类别。
