An evaluation of risks versus benefits from new products should be encouraged, even when dealing with agents which may cause cancer or malformations in laboratory animals, because there is evidence that safety thresholds exist even for such exposures. However, it is not easy to describe risk and benefit in comparable terms when they may involve generations to come and events in the future.
即使在处理那些可能在实验动物身上引发癌症或畸形的制剂时,也应鼓励对新产品的风险与益处进行评估,因为有证据表明,即便针对此类暴露,安全阈值也是存在的。然而,当风险和益处可能涉及子孙后代以及未来事件时,要以可比的方式描述它们并非易事。
