化学物的安全评价化学物毒性虽然是化学物内在的、损害活生物体的性能,但若其剂量减少,就不足以引起损害,即所谓“安全”。一般承认的安全(safety)是指在日常使用和接触化学物的数量和情况下,不会引起损害作用的可能性。由于不易明确地作出“安全”或“不安全”,又常用危险度这一
Chemical Safety Assessment Chemical Toxicity, although chemical in nature, compromises the performance of living organisms, but if the dose is reduced, it is not enough to cause damage, the so-called “safety.” It is generally acknowledged that safety refers to the possibility of no damaging effects in the quantity and circumstances of daily use and exposure to chemicals. Since it is not easy to make “safe” or “unsafe” explicitly, it is also commonly used
