LD50 refers to ...........
Answer: A
LD50 is the dose at which 50% of all test animals die.
LD stands for lethal dose. LD50 is the dose, usually in mg of substance per kg of body weight, that kills half of a test population within a set period. It is the standard measure of acute toxicity: the lower the LD50, the more toxic the substance.
The dose at which 50% of the animals show a specified response, short of death, is the ED50 (effective dose). The dose that kills all the animals is the LD100. The lowest dose that kills any animal is the LDLo (lowest lethal dose). Each is a different point on the dose-response curve.
