  1. LD50 is lethal dosage.
  2. QUESTION: Assuming that these compounds are similarly toxic to humans, how much of each compound would be required to reach the LD50 for a 150 pound human?  Show your calculations.
  3. Which of the two compounds is more toxic? How can you tell? (2pts)

Thank you for the opportunity to help you with your question!

LD stands for "Lethal Dose". LD50 is the amount of a material, given all at once, which causes the death of 50% (one half) of a group of test animals. The LD50 is one way to measure the short-term poisoning potential (acute toxicity) of a material.

Toxicologists can use many kinds of animals but most often testing is done with rats and mice. It is usually expressed as the amount of chemical administered (e.g., milligrams) per 100 grams (for smaller animals) or per kilogram (for bigger test subjects) of the body weight of the test animal. The LD50 can be found for any route of entry or administration but dermal (applied to the skin) and oral (given by mouth) administration methods are the most common.

LD01 Lethal dose for 1% of the animal test population

LD100 Lethal dose for 100% of the animal test population

LDLO The lowest dose causing lethality

TDLO The lowest dose causing a toxic effect
