慢性毒性研究提供了有关可能在相当一部分的测试物种寿命中反复暴露可能产生的健康危害的信息。
Studies provide data about toxic effects of a substance, indicate target organs and the possibility of accumulation. They can also provide estimates of no-observed-adverse effect levels to help establish safety criteria for human exposure.
Test duration ranges from 26 to 52 weeks, depending on test species. The majority of chronic toxicity studies are carried out in rodent species, but NHP are also used.
用于慢性毒性研究中使用的三种主要施用途径是口服,皮肤和吸入的。该路线的选择取决于测试化学品的物理和化学特征和人类暴露的主要途径。
