ED50 is a critical parameter in toxicology for several reasons:
Risk Assessment: It helps in evaluating the potential risk associated with exposure to a chemical or drug. Safety Margin: By comparing ED50 with toxicological benchmarks like LD50 (Lethal Dose 50), scientists can calculate the safety margin and therapeutic window of a substance. Regulatory Compliance: Regulatory agencies use ED50 data to establish safe exposure limits and guidelines for chemicals and pharmaceuticals.
