Toxicology is a field of science that helps us understand the harmful effects that chemicals substances or situations can have on people animals and the environment. The LD 50 is one way to measure the short-term poisoning potential acute toxicity of a material. To describe toxic effects toxicologists use the symbol LD50 which is the dosage mgkg body weight causing death in 50 percent of exposed animals Used to compare the toxicities of different chemicals.

The LD50 is best described as which of the following. Toxicologists use the term LD 50 to describe the number of grams of a substance per kilogram of body weight that constitutes a lethal dose for 50 percent of test animals. Calculate the number of arsenic III oxide formula units corresponding to an LD 50 value of 0018 for a 212-lb man assuming that the test animals and humans have the same LD 50.

C the dose at which 50 of an exposed population develops a chronic effect from the toxicant. Median lethal dose LD 50. The LD50 confidence interval estimation is expressed in a lower and upper bound for an interval that has a known probability or confidence of containing the true value of the LD50.
