In the realm of Toxicology, Annex IV is significant because it identifies substances that are recognized as having a low potential for adverse effects on human health and the environment. This means toxicologists can focus their research and testing efforts on substances not listed in Annex IV, which are potentially more hazardous. By streamlining the regulatory process for these low-risk substances, toxicologists can allocate resources towards the evaluation of chemicals with less known safety profiles.
