Overview of toxicological testing

Toxicological tests play an important role in ensuring the safety of food, cosmetics and chemical products. Through animal experiments and human observations, the toxicity and potential hazards of a chemical are clarified in order to evaluate the safety of human use of these chemicals and to provide theoretical basis for the formulation of preventive measures, especially health standards.
