ActiveTesting of chemicals - Delayed neurotoxicity of organophosphorus substances 28-day repeated dose study
化学品（有机磷化合物) 28天重复剂量的迟发性神经毒性试验
Application Summary AI generated
This standard specifies the procedures for a 28-day repeated dose study to evaluate the delayed neurotoxicity of organophosphorus substances in laboratory animals. It is applied in chemical safety assessment, particularly for pesticides and industrial chemicals, to identify potential long-term nerve damage after repeated exposure. The test is used by toxicology laboratories and regulatory agencies to support risk classification and product approval in healthcare and chemical industries.
