LD50, or lethal dose 50, refers to the amount of a substance that causes death in 50% of a test population. This measurement is crucial for assessing the toxicity of various substances, helping researchers understand the potential risks associated with exposure to chemicals or drugs. The LD50 value provides insight into the relative toxicity of a substance compared to others and is often used in toxicology studies to evaluate the safety and hazard levels of different compounds.
