Absolute lethal concentration, LC 100; Absolute lethal dose, LD 100 The most referenced value in the chemical industry is the median lethal dose, or LD50. This is the concentration of substance which resulted in the death of 50% of test subjects (typically mice or rats) in the laboratory.
In toxicology, the median lethal dose, LD 50 (abbreviation for "lethal dose, 50%"), LC 50 (lethal concentration, 50%) or LCt 50 is a toxic unit that measures the lethal dose of a given substance. [1] The value of LD 50 for a substance is the dose required to kill half the members of a tested population after a specified test duration.
