Answer :

LD50 refers to the lethal dose for 50% of the test population. LD stands for "Lethal Dose," and the 50 refers to the fact that the lethal dose is lethal for 50% of the population.

If a group of animals or humans are given a certain substance, the LD50 is the dose at which 50% of the group will die. This measure is often used in toxicology studies to determine the toxicity of a substance. For example, if a group of rats is given a certain chemical and the LD50 is found to be 500 mg/kg, it means that if 500 mg/kg of the chemical is given to a group of rats, 50% of the rats will die. LD50 is a useful measure for comparing the toxicity of different substances, as a lower LD50 indicates a higher level of toxicity.
