What is an LD50 and How Does it Relate to Species?
The LD50 (Lethal Dose 50) is a common measure in toxicology that indicates the dose of a substance that is lethal to 50% of a test population. The LD50 value can vary widely between species. For example, a substance with a high LD50 in rodents may have a much lower LD50 in humans, highlighting the importance of species-specific data in toxicity testing.
