Which measure indicates the amount of a chemical that kills 50% of the animals in a test population?

  1. LD50

  2. LC50

  3. Chronic Toxicity

  4. Acute Toxicity

The correct answer is: LD50

The correct measure in this case is known as LD50, which stands for lethal dose 50. LD50 refers to the amount of a chemical that will kill 50% of the animals in a test population. This measure is used to determine the potential toxicity of a substance. Option B, LC50, refers to the lethal concentration 50, which is a measurement of the concentration of a substance that will kill 50% of a test population. Option C, Chronic Toxicity, refers to the long-term effects of exposure to a substance, while option D, Acute Toxicity, refers to the immediate effects of exposure to a substance. Both of these options are not the correct measure for determining the toxicity of a substance. Therefore, the correct answer is A, LD50.
