This one almost has the same meaning, but the units are different.
The dose that will kill 50% of the test population is referred to as LD50.
The term "exposure concentration of a hazardous chemical fatal to half of the test animals" is abbreviated as (LC50)
LD50 is measured in milligrams per kilogram of the test animal's body weight (which must be mentioned).
The test animal's body weight must be indicated. The test animal was exposed to the drug via inhalation for a predetermined amount of time. The LD50 and LC50 numerical values are quite variable.
The LD50 and LC50 values may be used as a basis for classification. Animals, primarily rats, mice, and rabbits, are used in laboratory testing to evaluate the effects.
The test material or preparation may be administered to the animal orally, physically, inhaled, intravenously, or intravenous injection. The metrics LD50 and LC50 are used to quantify the outcomes of various experiments so that they may be compared
