English: Steps and examples of calculating lethal doses of a specific individual (specified weight) with a specific substance type. Additionally, calculations and examples are displayed of measuring tablets to weighted individuals in calculating lethal doses.
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.
LT50 is the median Lethal Time (time until death) [1] [2] after exposure of an organism to a toxic substance or stressful condition. LT50 is commonly used in toxicology studies to quantify amount of a stressor necessary to kill an organism. LT50 can be used in conjunction with EC50 (median Exposure Concentration) for even more precise ...
The median lethal dose, LD 50 (abbreviation for "lethal dose, 50%"), LC 50 (lethal concentration, 50%) or LCt 50 (lethal concentration and time) of a toxin, radiation, or pathogen is the dose required to kill half the members of a tested population after a specified test duration.
Effective dose: It is the minimum dose or concentration of a drug that produces a biological response in 50% of a population being studied. Median lethal dose: For either drugs or toxins, it is a toxic unit that measures the minimum dose that causes death (lethal dose) in 50% of cases

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.
